2.1.6 Labels on the product


The safety labels communicate the following:
• The severity level of the risk (i.e., signal word, "DANGER" or
"WARNING")
• The nature of the hazard (i.e., the type of hazard - cutting parts, high
pressure, falling objects, dust, live parts, etc.)
• The consequence of interaction with the hazard (i.e., cut, injection,
crushing, explosion, electrocution etc.)
• How to avoid the hazard
IMPORTANT! Keep the safety labels clean and visible at all times.
Check the condition of safety labels daily. Safety labels and
instructions, which have faded, been damaged, been painted over,
come loose or that do not meet the legibility requirements for safe
viewing distance must be replaced before operating the product.

Installing the safety label


1. Make sure that the temperature of the surface on the area where the
safety label is to be installed is more than +5°C.
Note! Sandvik recommends using Easywork Sprayclean degreasing agent
or equivalent for cleaning the dirty surface. It is important that the
agent does not leave any agent layer on the surface.
2. Clean the surface carefully of grease, oil, silicon and such dirt when
installing the labels and shields.
Note! Do not install the safety label on the hole. The stability and life cycle
of the safety label decrease significantly when dirt goes through the
holes on the back side of the label.
3. Put a masking tape as a corner on the upper edge and left side on the
surface for marking the position of the safety label.
4. Remove the cover paper carefully from the safety label to not get dirt on
the sticking surface.
5. Remove only the upper part of the cover paper if the cover paper is a
two-piece.
6. Fold the cover paper for one centimeter from the upper edge if the cover
paper is a one-piece.
7. Set the safety label carefully to its position on the marked corner and
press its upper edge tightly to the surface so that the safety label cannot
move.
8. Lift the lower edge of the safety label carefully so that the safety label
does not come loose from the sticking surface and remove the rest of the
cover paper (or the other part of the two-piece).
9. Pull the cover paper downwards to remove it.
Note! The safety label must be installed at once to its correct position to
make sure its stability.
10. Make sure that the safety label is in the planned position.

Note! Make sure the spatula is clean that the safety label does not get
scratched.
11. Press the safety label to the surface from up to down with a spatula or
piece of carton.
12. Remove the masking tapes.
Note! The glue on the safety label gets full adhesion (sticking time) in 48
hours from installing.

Note! Do not wash the machine with a pressure washer during the sticking
time (48 hours).
13. Make sure that the machine is in the temperature of at least +5°C for
two to three hours after installing the safety labels.

Removing the old safety labels


1. Warm the surface of the safety label with a warm-air heater so that the
glue of the safety label warms.
2. Remove the safety label carefully with a metallic spatula.
3. Clean the machine surface, refer to step 2 in "Installing the safety label".
Note! Keep the safety labels clean and visible at all times. Check the
condition of safety labels daily. Safety labels and instructions, which
have faded, been damaged, been painted over, come loose, worn-out
to be as unreadable or that do not meet the legibility requirements
for safe viewing distance must be replaced before operating the
product.
4. Install a new safety label, refer to steps in "Installing the safety label".

instructions.

The machine should be isolated before performing any maintenance work.


The purpose of isolating machinery is to allow work to be undertaken safely
with no danger to life, or injury to people, or possibility of property damage.
Any instructions given in laws and regulations, any orders given by local
authorities, and all protective measures must be strictly adhered to. Check
the isolation requirements and ensure compliance before starting the job.
Maintenance and repair work on the pressurized systems may only be
carried out by persons who have received the training required for the work.
Do not start work that is not fully familiar to you.

Hydraulic system isolation


WARNING! HAZARDOUS STORED ENERGY!
There may still be pressure remaining in the system even when the
gauges show 0 bar.
Proceed with caution when working with hydraulic systems. Use
approved personal protective equipment.

When the machine is switched off, be aware that there is still stored
pressure in the hydraulic system. Hydraulic system can store pressure in
the brake circuit accumulators and rock drill accumulators, as well as in
machine components which are supported by the hydraulic system. All
major machine assemblies should be lowered to the ground or supported to
isolate any hydraulic energy.
Release pressure from the brake accumulators as follows:
• Shut down the engine.
• Turn the ignition switch to the middle position.
• Press the brake pedal several times.
• Review the pressure gauges in the tramming panel to verify that the

Operator's Manual DT621

Release any stored rock drill accumulator pressure by opening the filling
valve of accumulator and verifying zero pressure on adjacent pressure
gauge. Never direct the discharge opening at anyone. Always direct the
discharge opening to an empty area to protect those in the immediate
vicinity.
In spite of these precautionary measures, some of the hydraulic system's
subsystems may still be pressurized (e.g. boom circuit, rod handler circuit,
rod retainer circuit). Always use approved personal protective equipment
and proceed with caution.

Air system isolation


If the air system is equipped with an open-type 2/2- directional valve, it
automatically releases the pressure from the air system when the
compressor and power pack are switched off. If the air system is equipped
with air receivers (optional), it will take longer to depressurize the system.
In spite of these precautionary measures, the system may include some
subsystems, from which pressure has not been released. When performing
any maintenance or repair work, always use approved personal protective
equipment. Proceed with caution and comply with all safety requirements.

Fuel system isolation


If the fuel filter is equipped with a shutting tap, isolate the fuel system by
using the tap. This will prevent any environmental contamination during

• Roof panels in the cabin are made of fire retardant material.
• Cables in the engine compartment are inside a fireproof sleeve.
In spite of engineering and use of fire retardant materials, there are also
flammable materials in the machine e.g. inside switchgears, in valves,
plastic components, batteries and tires. Also oils, greases and paints used
in the machine are flammable materials. Keep the machine clean at all
times; dirt in the machine increases fire risk.

module is disabled.

Engine switch-off system with ANSUL (optional)


The engine switches off automatically 5 seconds after the fire extinguishing
system has been actuated. To avoid automatic switch-off, immediately
press and release the delay button on the control unit. Pushing the delay
button will postpone the automatic engine switch-off by 5 seconds. If
necessary, use the button until you have found a suitable parking place.

FS1000 Fire suppression system (optional)


The FS1000 fire suppression system is installed in the machine for fire
suppression. The system is a fixed foam fire suppression system. Due to
the water content in the foam extinguishing agent, this fire suppression
system is suitable for ambient temperature above 0 °C. The primary
function of the system is to protect the operator. It greatly reduces risk to
people and property by providing effective fire protection and, therefore,
safer operating conditions. The system has been specifically designed to
suppress hydrocarbon fuel oil fires by application of foam extinguishing
agent. The foam will cut the fire's oxygen supply off and act as a vapor seal
over the fuel. The foam's water content cools the area down, which reduces
risk of re-ignition.
The discharge circuit nozzles are arranged in the form of a ring. It consists
of fire rated hose with a series of nozzles aimed at the risk areas.
The location of the fire suppression nozzles and manual actuators are
represented in the figure(s) below.

Automatic activation of the FS1000 system


The system is activated automatically by the fire detection and system
activation tubing when the heat caused by the fire reaches approximately
150 °C.
Note! The system may activate automatically, but if you observe fire on the
machine, always activate the system manually.

Engine shutdown kit with FS1000


The engine shutdown kit's primary function is to detect when the fire
suppression system is activated and to provide the operator with an
audiovisual alarm. After a delay period, the engine will shut down.
The kit contains a double pressure switch (3) and an electronic alarm/timer
box (4).

A B

A = canopy, B = cabin

Double pressure switch


The double pressure switch is factory set to 900 kPa falling and will switch
contacts if and when the system pressure falls below the setting of the
switch. Such a drop of pressure can be due to system activation or
pressure loss from a leak.

The double pressure switch is wired into the electronic alarm/timer box. If
turned on, the double pressure switch will trigger an audiovisual alarm
(warning light (2) or (3) will turn on and an audible alarm will sound). When
the pressure starts to drop, the 6 second delay timer will begin.
Timers are factory set to an automatic 6 seconds, with a 20 second manual
timer reset. If there is no operator intervention, the automatic engine
shutdown will occur 6 seconds after the fire suppression system is
activated. If the shutdown button (4) is pressed during the 6 seconds
countdown, the timer will reset to extend the delay by an additional 20
seconds delay. The additional time allows the operator to have both hands
free to drive the machine for another 20 seconds before the engine
automatically shuts down.
The alarm/timer box is also fitted with a manual override button (6) to allow
the machine to be moved, if necessary. However, to reduce the risk of the
machine being operated with the fire suppression system discharged, the
override button must be pushed inward and held (it is a spring return
button) to maintain override. As soon as the button is released, the
machine will return to the shutdown mode.

2.7.5 After a fire


Once the fire is out and the machine has cooled down, open the ventilation
hatches to clear the machine of smoke and gases. Avoid breathing in the
combustion gases. Keep a hand-held fire extinguisher close and ready to
use during ventilation.
Wash the machine with plenty of water as soon as possible after
extinguishing, because the powder used can cause corrosion, especially to
the cables.
Empty tanks and gas cartridges must be replaced before using the
machine. Only authorized service personnel may remove and fit powder
tanks and gas cartridges.
Do not start the machine again until the cause of the fire has been
established and the fault has been repaired.
Report all fires to the supervisor.

2.8.3 Dust

DANGER
DUST HAZARD!
Breathing dust will cause death or severe injury.
In dusty conditions always wear approved respirator.

Breathing or inhaling dust particles will cause death or severe injury. Always
work with a respirator approved by the respirator manufacturer for the job
you are doing. It is essential that the respirator that you use protects you
from the tiny dust particles which cause silicosis and which may cause
other serious lung diseases. You should not use the product until you are
sure your respirator is working properly. This means the respirator must be
checked to make sure that it is clean, that its filter has been changed, and
to otherwise make sure the respirator will protect you in the way it is meant
to.
In any workplace where respirators are necessary to protect the health of
the employee, the employer must establish and implement a written
respiratory protection program with work site specific procedures and
elements including but not limited to the selection of respirators, proper
usage, maintenance and care, cleaning and disinfecting and training.
Regularly clean your working environment properly to minimize the dust
level in the air. Always make sure dust has been cleaned off your boots and
clothes when you leave your shift.
Respiratory silica dust is a hazard, which requires special attention. The
smallest particles of dust are the most harmful. They may be so fine that
you cannot see them. Remember, you must protect yourself from the
danger of breathing or inhaling dust.

2.9 Emergency procedures


It is the employer’s responsibility to plan and prepare site specific
instructions to be followed in case of an emergency or an accident. The
machine manufacturer can also give certain general guidelines which can
be used as help in establishing the required procedures. The following
information should be considered when devising a site specific emergency
plan. This list is not meant to be comprehensive.
• Emergency stop: If the machine has to be stopped immediately, use the
emergency stop functions. Emergency stopping stops all the ongoing
functions. For more information, see the section, ”Use of emergency stop
function”.

94 (334) Copyright © Sandvik


ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

• Emergency exit: In an emergency situation, use the safest escape way


or emergency exit. Also rescue personnel can use these exits to reach a
user in the operator station. For more information, see the
section, ”Emergency exit”.
• Loss of stability: If there is sudden loss of stability during tramming, the
safest place for the user is usually inside operator station, seated on the
operator seat and seat belt fastened.
• Falling objects: In case of falling objects, the operator should stay inside
operator station until it is safe to leave the machine. The operator may
also, when possible, move the machine away from the hazard zone,
without leaving the operator station.
• Fire: In mining conditions, it is extremely important to avoid fires. If an
accident does happen and there is a fire, it has to be extinguished as
soon as possible. For more information, see the section, “Fire risk control
measures”.
• Accidents with chemicals: In an emergency situation or accident where
chemicals are involved, see the required first aid measures and
instructions in the material safety data sheets which have been delivered
with the machine manuals.

Copyright © Sandvik 95 (334)


ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

• Electric accidents: If the machine touches an electric power line, the


following instructions may prevent injuries or death.
- If you are standing outside the machine, do not touch any part of the
machine or try to get onto the machine. Keep everybody away from
the machine.
- If you are on the machine, do not try to get off it. If the machine is
touching a power line, the machine can catch on fire. If the machine
has rubber tires, leave the machine as soon as the tires start
smoking. JUMP OUT! Do not make yourself a conductor for the
electric current to flow from the machine to the ground. Move away
from the machine by jumping, or by leaping so that only one foot at a
time touches the ground. The electric field in the ground can cause a
dangerously high voltage between your legs. You will not be in safety
until you are about 20 meters away from the machine.
- If the boom or some other component of the machine touches an
electric power line, the whole machine becomes live. Although the
insulating rubber tires may make the situation seem safe, a person
standing on the ground and touching the machine can get a fatal
electric shock.
- If you come to a place where an electric accident has taken place, do
not risk your own life by acting incautiously to save others. Try to find
out whether a high or a low voltage is involved. Where high voltage is
involved, do not start any rescuing attempts until the power company
has cut off the voltage. It can be dangerous even to approach a
person in contact with the electric conductor, or with the machine that
touches the conductor. Remember that high voltage power lines
have no fuses that blow; the conductors are always dangerous, until
a qualified electrician has made them dead.
- If a person is in contact with a low voltage line or with a machine that
is touching a low voltage line, rescuing can be attempted by using a
dry and clean rope, or a dry and unpainted piece of wood. Anyone
who is attempting the rescue must keep as far away from the victim
as possible. The victim must not be touched until he is completely
disconnected from the live components. If the victim is unconscious,
first aid measures must be started immediately.
• Emergency situation with utility boom (only if the drill rig is
equipped with a utility boom): In an emergency situation, when the
control place has to be changed from the basket to the operator station,
use the spare key located in the operator station. For more information,
see the section, "Using utility boom controls" in the operator's manual.
After an accident or emergency situation: Being on site where an
incident has occurred, do not take any actions with the equipment involved.
Do not speculate or give opinions on the cause. Contact your Sandvik
representative to get more information.

2.11.3 Disposal
This section gives useful advice to identify which parts of the product are
recoverable, with a view to recycling or reusing the materials or
components for new applications. To ensure environmentally sound
treatment of a product and all of its components, the recovery issues are
already taken into account during the design phase of the product. Correct
handling of waste materials reduces costs and promotes the best use of the
components and materials.
• Machine body: All the steel constructions and the copper and aluminum
in the electrical wiring are recyclable. The metals can be melted and
used as raw material for new products, except for parts that have been in
contact with substances that are regarded as hazardous waste. The
contaminated parts can usually be simply cleaned or rinsed, after which
they can be recycled.
• Plastic: Most plastic parts are recyclable, similarly to the metals. Each
plastic part carries information on the material used and a manufacturing
date, which can be used for determining whether the part can be
recycled.
• Rubber parts and tires: Tires can be recycled, and used as recovered
material. Worn-out tires can be returned to the dealer from whom they
were originally bought. Rubber tubes and hoses must be cleaned before
they are disposed of.
• Glass: Glass can be recycled, as well as laminated glass such as
windshields and windows. Various types of glasses shall be sorted
according to local rules and regulations.
• Electrical and electronic waste: Electrical and electronic components
contain valuable and recyclable materials, and in addition a set of
chemicals and heavy metals. Electrical components that are classified as
hazardous waste (accumulators, batteries, circuit boards) and other
hazardous waste must be delivered to a licensed waste treatment
location or be disposed of according to local regulations. Never dump
hazardous electrical or electronic waste.
• Gas discharge / xenon lamps: Gas discharge lamps contain mercury
and are hazardous waste. They must not be dumped. Lamps must be
taken care of by an authorized hazardous waste disposal company.
• Air conditioning units: Air conditioning units, which contain CFC and
HCFC compounds, must always be delivered for treatment to a licensed
waste disposal facility.

102 (334) Copyright © Sandvik


ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

• Batteries: Batteries are classified as environmentally hazardous material


and require special handling and storing in accordance with applicable
ordinances, rules and regulations. Batteries can cause serious harm to
the ecosystem; lead in the batteries is highly toxic and it accumulates in
the body over time. The disposal shall be taken care of by an authorized
waste disposal company. According to producer responsibility, producers
of batteries and accumulators are also responsible to accomplish the
waste management of batteries that they have placed on the market.
Batteries also contain diluted sulphuric acid. The acid is extremely
corrosive and it burns skin, eats holes in clothing, and can cause
blindness if it gets in the eyes. If you get battery acid on your skin, or
clothes, rinse them immediately with water. Use sodium bicarbonate to
neutralize the acid. If it gets in the eyes, flush the eyes with water, and
call a doctor.
• Oils and fluids: Oil waste must not be disposed of by burning, and
under no circumstances must oil be poured down the drain or into water
systems. Waste oil shall be collected in appropriate containers. The best
containers for collecting oil waste are the original containers for the oils.
The original containers already have the necessary warning labels, are
easy to close, and can be moved around fairly easily. Always strike out
the product name on the label and clearly label the container “oil waste”.
Empty oil containers must not be dumped in landfills without having been
cleaned. Cleaned plastic containers can be disposed of as regular waste.
Most countries have arranged a recycling system for metal barrels.
Greases, fuels, solvents, and other substances must not be mixed with
oil waste.
• Solid waste containing oil: Oil filters, oil rags, fuel filters, and oil
absorbents must be collected in a separate container.
• Solvents and oil trap sludge: Solvents and sludge that has collected on
the surface of the oil traps can both be collected in a same container. The
surface layer in the oil traps must be removed regularly, and the entire
trap must be drained at least once a year, including the sludge at the
bottom. Do not mix the oil trap sludge with oil waste.
• Fuel oil: Fuel oil is hazardous waste that must in all cases be processed
by an authorized waste treatment plant.
• Radiator, brake, and clutch fluids: Used radiator, brake, and clutch
fluids contain traces of heavy metals, zinc, and copper, for which reason
they must not be poured down the drain or mixed with oil waste. They are
to be collected in a separate, labeled container and delivered to the same
plants as the oil waste.

2.12 Potential product related hazards identified by the user


Sandvik has taken all necessary precautions to design a safe machine. If,
in spite of these efforts, you observe a hazard for which you believe there
are insufficient safety measures, immediately inform your supervisor. If
necessary, also inform the other employees working with the product.
Report the hazard to your local Sandvik representative. Do not perform a
task if you are unable to perform the task in a safe manner.

Ai r-t o-ai r Cool er


EGR Cooler

Compressed AirFrom Turbocharger

Cooled exhaust gas recirculation (EGR):


• EGR cools and mixes measured amounts of cooled exhaust gas with
incoming fresh air to lower peak combustion temperatures, thereby
reducing NOx.
Exhaust filters:
• These engines utilize a catalyzed exhaust filter that contains a diesel
oxidation catalyst (DOC) and a diesel particulate filter (DPF).
• The DOC reacts with exhaust gases to reduce carbon monoxide,
hydrocarbons, and some particulate matter (PM).
• The downstream DPF traps and holds the remaining PM.
• Trapped particles are oxidized within the DPF through a continuous
cleaning process called passive regeneration. Passive regeneration
occurs during normal operating conditions when heat from the exhaust
stream and catalysts within the exhaust filter trigger the oxidation of the
trapped PM. If passive regeneration cannot be achieved due to low
temperature, load, or speed, then PM is removed using active
regeneration.

Main instrument
The main instrument consists of a conventional tachometer, multifunction
LCD matrix display, and the display group shift button.
In addition to the default view (operating hour meter), several other
practical display modes can be viewed in the LCD display. However, note
that the alarms, CAN fault codes, and warnings are available only when
they are active or include data that has not been reset.

4 4+1-digit resettable operating hour meter
5 Measurement unit for the variable
6 Display group shift button

Operating hour meter


The LCD display is an operating hour meter by default. The number after
the decimal point in the resettable operating hour meter refers to tenths of
hours. The meter can be reset by pressing the shift button for more than
two seconds.

Alarms
If an alarm is triggered, the LCD display shifts automatically to the alarm
screen. The general alarm symbol starts to blink alternately with the symbol
indicating the alarm type. If several alarms are triggered at the same time,
the most critical alarm will be displayed. The alarm list in the alarm display
can be browsed by pressing the shift button briefly.
The alarm can be reset by pressing the shift button for more than two
seconds. The value displayed last will return to the LCD display. If the
problem causing the alarm remains, the general alarm symbol remains
displayed on the left-hand side of the screen. The vertical line to the right of
the alarm symbol indicates that the alarm does not refer to the currently
displayed value. If the alarm is reset and the problem causing the alarm is

Operator's Manual DT621

cleared, the alarm will be removed from the list of active alarms. Although
the problem is cleared, the triggered alarm must be reset in order to
remove it from the alarm list.

CAN fault codes


If a new trouble code is received from the diagnostics (DTC, for ‘diagnostic
trouble code’), the LCD automatically shifts its view to the CAN fault code
screen. The code symbol (an open book) is displayed on the left side of the
screen, followed by the code name in the middle. The code number from
the buffer is displayed on the right-hand side.

Physical values
The physical value display shows the symbol of the current physical value.
In standard mode, the physical value is displayed on one line, followed by
the measurement unit. If the value is outside the defined range, the display
shows ‘------’. A probable cause for exceeding the limits is a damaged
sensor or cable.
To view the physical values in the physical value display, press the display
group shift button for more than 0.5 seconds.

Warnings
A special graphic symbol (ISO) blinks on the warning display. The warning
can be reset by pressing the shift button for more than two seconds. If there
are no other alarms and warnings to reset, the last active screen will be
displayed. If several alarms are active at the same time, the most critical
alarm will be displayed. If the problem causing the alarm is cleared, the
alarm will be removed, if it has been reset.
If you want to display different warnings on the warning screen, press the
shift button for more than 0.5 seconds.

Speedometer (optional)
Speedometer is the final view on the LCD display. Without speed
measurement option it shows 0 km/h.

it can be turned off by pressing the acknowledgement
button (S505). After this, the water pump must be start-
ed using the switch (S501).
When the temperature of the compressor's output air
reaches 100°C the indicator light goes on. Compressor
is still functional, but the warning light indicates either
possible failure, or need for maintenance of the com-
pressor, which should be checked as soon as possible.

100°C.
When temperature reaches 115°C the power pack,
compressor and water pumps stop. This is an indication
that something has failed in the compressor and shall
be immediately investigated and fixed.
The indicator light goes on and the power pack, com-
pressor, and water pumps stop if the oil level drops be-
low the allowed minimum. The level monitoring system

Operator's Manual DT621

4.1 Starting procedure


4.1.1 Starting the diesel engine
WARNING! MOBILE MACHINERY HAZARD!
Moving machine and its moving parts could cause death or severe
injury.
Before starting, always ensure that there are no people in the hazard
zones.

WARNING! SUFFOCATION AND POISONING HAZARD!


Breathing exhaust fumes can cause death or severe injury.
Do not use the unit in enclosed spaces without adequate ventilation.
The greatest risks related to diesel engine exhaust fumes are caused
by nitrogen oxides and carbon monoxide.

RISK OF DAMAGE TO THE HYDRAULIC SYSTEM!


NOTICE Avoid simultaneous use of the power pack and the diesel engine.
The simultaneous use may cause damage to the hydraulic system.

Note! Conduct a ‘walk-around’ inspection of the machine. Any minor


problems observed should only take a few minutes to fix and, in so
doing, the need for later larger repairs can be avoided.
1. Turn the battery isolation switch (S1) to the ON position.
2. Ensure that all emergency stop buttons have been released.
3. Ensure that none of the power packs is running.
4. Check that the gear is on neutral.
5. Ensure that the parking brake has been engaged (parking brake button
(S21) has been pressed down).
6. Switch on the power by turning the power switch (S2) to the middle
position.
The indicators light come on.
7. Check that all indicator lights are illuminated. If any of the indicators is
not lit, find the cause and fix the defect before starting. The lights go off
when pre-heating is finished and the engine can be started. If the drill rig
has Tier4 engine, wait until the preheat indicator light in the tramming
panel comes off.
If the drill rig has Tier4 engine, check the function of the DPF-light
by turning the regeneration switch (S22) to ON position and return the
switch then to normal position.
Note! The engine must not be started if any of the indicators is not
functional.
8. Sound the horn by pressing the button (S9).

Operator's Manual DT621

9. Depress the accelerator pedal half way, and start the engine by turning
the power switch (S2) to the right.
Crank the engine for a maximum of 20 seconds at a time. If the engine
does not start during that time, release the switch and wait for
approximately one minute before trying again. The one-minute period is
needed to restore the charge of the batteries, and also prolongs their
service life.
10. Release the power switch (S2) immediately once the engine has
started.
The switch returns to its normal position.

Once the engine has started the indicators should go out immediately. An
exception to this is the brake pressure indicator lights (on the gauges P3
and P4), which go off once the pressure has risen sufficiently.

Cold starting
When the drill rig is used in extremely cold conditions (below -20 °C), the
engine must be heated to ensure circulation of the lubrication oil. Heating
can be performed with an oil pan heater. Parts for connecting pre-heating
units, however, are provided only on engines intended for operation in very
cold conditions.
Cold starting is performed in the same way as a normal start, except that
the interval between start-up attempts must be at least two minutes, and a
single start-up attempt must not exceed 15 seconds.
For cold-starting, the batteries must be in good condition; i.e., fully
NOTICE charged. To ensure this, the batteries should be removed and stored
in a warm place.

Do not load the engine when it is cold. Allow the engine to run at low
NOTICE speed until the lubrication functions properly.

4.1.2 When the diesel engine is running


1. Once the engine is running smoothly, allow it to run down to idling speed.
2. Increase the engine's running speed by pressing the accelerator pedal.
3. Run the engine with a reasonable load and at varying speeds for a few
minutes until it has reached its normal running values:

F G

A Engine oil pressure: in B Engine temperature: below


idling speed, min 0,5 bar 100 °C
C Transmission feed D Transmission oil
pressure: 16,5 to 19,3 bar temperature: below 90 °C
E Voltmeter: 24 to 27 V F Front brake pressure: 135
to 160 bar
G Rear brake pressure: 135
to 160 bar

Note! If any of the values is outside the normal range, switch off the engine
and determine the cause of the problem.

4.2 Shut down procedure


4.2.1 Stopping the diesel engine
RISK OF COMPONENT MALFUNCTION!
Do not open the battery isolation switch while the engine is running.
NOTICE Opening the switch could cause the AC alternator, current controller,
or lamps to burn out.

RISK OF ENGINE DAMAGE!


NOTICE Do not stop a hot engine directly at high revolution speed.

1. Allow the engine to idle for a few minutes to allow temperature


equalization.
2. Shut down the engine by turning the power switch (S2) to the left.
Note! In a problem situation engine can be stopped via the Stop-
button at the side of the engine.

4.3 Using tramming controls

WARNING
TIP OVER HAZARD!
Machine tip over could cause death or severe injury.
Always wear a seat belt while tramming.
Transporting passengers is prohibited.

4.3.1 Before tramming


• Check the location and operation of the emergency stop buttons.
• Check the operation of the lights, gauges, indicator lights, and horn.
• Ensure that all external connections that require attention or can cause a
safety hazard have been disconnected.
• Ensure that all cables and hoses have been reeled in and stowed in heir
appropriate places, properly fastened.
• Ensure that all accessories, loose structures and tools are securely
fastened.
• Ensure that the drill rig is in tramming position.
• Test the operation and capacity of the parking and service brakes
according to chapter “Testing the brakes”.
• Ensure that there are no persons in the drill rig's hazard zone.

Testing the brakes

WARNING
RISK OF LOSING THE CONTROL OF THE VEHICLE!
Faulty brakes could cause personal injury or equipment damage.
Read these instructions thoroughly before tramming the drill rig.
Always ensure the proper functioning and sufficient capacity of the
brakes before tramming. Do not operate the drill rig if the brakes are
faulty.

The holding effect of the service brakes depends on both the condition of
the brake components and on the pressure acting in the brake circuit. The
operation and holding capacity of the brakes must always be ensured
before driving is started. Braking power is tested as follows:
1. Ensure that the parking brake is on.
2. Start up the engine and let the engine run until the transmission oil
temperature is normal.
3. Engage the 1st gear and select a safe driving direction.
4. Press slowly the acceleration pedal and raise the revolutions of the diesel
engine to the 1500 rpm => the machine must not move.
5. Release the acceleration pedal.
6. Engage the 2nd gear.
7. Press the brake pedal all the way down and keep it there.

P3 P4

The pressure should be at least 100 bar (P3, P4). The brake pressure
indicator lights on the instrument panel must go off.
8. Release the parking brake and simultaneously press slowly the
acceleration pedal and raise the revolutions of the diesel engine to the
maximum => the machine must not move.
9. Release the acceleration pedal.
10. Activate the parking brake on.
11. De-engage the gear and select the neutral driving direction.

If the brake test fails, do not operate the drill rig. Inform the brake test
failure to maintenance crew. Brake disc wear check and other needed
actions shall be performed to find out the reason for loss of brake holding
efficiency.

WARNING
RISK OF LOSING THE CONTROL OF THE VEHICLE!
Faulty brakes could cause personal injury or equipment damage.
the drill rig must not be trammed if the drill rig moves during the
brake test, if the brake pressure is below 100 bar, or the brake
warning light stays on. Tow the drill rig to the repair shop and refer
to the maintenance instructions for additional information about the
brake pressure accumulators and brake circuit.

Neutral brake system (option)


When the drive selector is in neutral position the brakes are on.

4.3.2 Tramming position


During tramming, the feeds must be on the top side of the booms. In
addition, the feed should be run to the extreme back position and its rear
end lowered to the boom. In this way, the feed is protected against
unnecessary rocking.
For practical reasons, the booms should be turned as close to each another
and to the carrier centre line as possible. This minimizes the drill rig's need
of space. For the same reason, the boom extension movement and the
feed transfer movement should be in their fully retracted positions.

RISK OF PROPERTY DAMAGE!


Tramming with lowered jacks could damage drill rig components.
NOTICE Before tramming ensure that the jack beam and the jacks are fully
retracted.

Safety canopy position during tramming and drilling

Safety canopy locking holes during tramming (1) and drilling (2)

WARNING! CRUSHING HAZARD!


Lowering canopy could cause death or severe injury.
When lowering the canopy, follow the movement of the lowering roof
to avoid being hit or crushed between the canopy and the control
panel. To avoid unintentional movement of the canopy, the locking
pins must always be fastened.

WARNING! SHEARING HAZARD!


Sliding canopy tubes can cause severe injury.
Do not touch the moving canopy tubes. Keep fingers out of the pin
holes and the protection plates in place.

Transporting drill steel with drill steel rack (optional)


Before loading the drill steel into the rack, check that the rack and locking
levers (if equipped) are in proper condition.

the rack one end at a time. Start by placing the other end of the rod to the
lower holder (closer to the front end of the machine) and then lift the other
end to the upper holder.
If the drill steel rack is equipped with a locking lever, ensure that it is locked
before moving the machine.
WARNING! RISK OF PERSONAL INJURY!
Modification of the drill steel rack, or transportation of more drill
steel than originally intended is strictly prohibited. Always follow the
maximum loading/pieces capacity of the drill steel rack.

• The driving direction is selected by pushing/pulling the lever in the


desired direction.
• The gear is changed by turning the lever either clockwise or
counterclockwise.
• Numbered LEDs indicate the selected gear and selected driving
direction.
• Use first gear when starting tramming and in situations in which the load
conditions and terrain prevent the use of higher speed.
• Switch to second gear when the speed approaches the maximum speed
for first gear, and when the load and terrain permit higher speed.
• Switch to third gear when the speed approaches the maximum speed for
second gear, and when the load and terrain permit even higher speed.

Note! • Always choose the speed range appropriate for the tramming
conditions.
• Always use first gear when tramming downhill. Never use a fast
tramming speed.
• Primarily use engine braking to control the speed.
• Avoid sudden braking and continuous use of the service brake.
• If the drill rig must be moved with the boom(s) separated, the
tramming speed must be kept as low as possible, and the lowest
gear should be selected. The allowed maximum speed is 3 to 5
km/h.

Operator's Manual DT621

RISK OF EQUIPMENT DAMAGE!


When changing to a lower gear, the tramming speed must be taken
NOTICE into consideration. Changing gear must not be performed when the
tramming speed is higher than the maximum speed for the gear you
wish to select.

RISK OF EQUIPMENT DAMAGE!


NOTICE Shift the transmission to neutral during idle periods.

RISK OF EQUIPMENT DAMAGE!


While driving the drill rig downhill, maximum allowed rpm shall not
NOTICE exceed. Light and sound signal in the tramming panel are activated,
when the maximum is exceeded.

4.3.4 Steering

The drill rig has hydraulic frame steering.


Notice that the steering reaction speed diminishes as the engine's rotation
speed decreases. Take this into account particularly when turning and
when driving in higher gears.

Use the hand knob for steering.


Middle-joint locking is optional in some drill rigs. In such drill rigs,
movement of the middle-joint during drilling is prevented by locking valves.

Striking the drill rig’s interior during a sudden stop could cause
death or severe injury.
Always use lap belt during tramming.
Use brakes smoothly, avoid sudden braking.
Never use the parking brake to stop the drill rig, unless in an
emergency.

Never keep your foot on the brake pedal when tramming. This will
cause the hydraulics system to overheat and induce premature brake
NOTICE damage.
Monitor the gauges and warning indicators. If you notice anything
abnormal, stop the drill rig, and inspect the cause of the problem.

Stop the drill rig by decreasing the engine speed and applying the service
brake.
The brake pedal is foot operated. Pressing the brake pedal engages the
brakes, and stops the drill rig. The harder you press the brake pedal, the
faster the drill rig will stop, and the greater the braking force.
Lifting your foot from the brake pedal will release the brakes, and the drill
rig will resume motion.

4.5.2 Preparations for moving the utility boom


WARNING! TIPPING HAZARD!
Faulty operation of the utility boom could result in death or severe
injury.
Before the utility boom operation ensure that the front jack beam is
extended and all jacks have been lowered to the ground. Check that
the jack extension indicator lights are illuminated.

A B C

The jacks function only when the key switch (S3) (D) has been moved to
the position "Control from the operator station". The key switch is located
on the tramming panel.
When you start using the utility boom, make sure that the front jack
extension indicator lights (A) is lit to indicate that the front jack extension
beams are fully extended (if the drill rig is equipped with an extendable front
jack beam), and that all four indicator lights (B) and (C) are lit to indicate
that the jacks have reached the ground.

The order of using front jack beam and jacks


1. Extend the front jack beam. The lights (A) light up to indicate that the
beams are out in their extreme position. (If the drill rig is equipped with an
extendable front jack beam.)
2. Extend the front jacks. The lights in buttons (B) light up to indicate that
the jacks have reached the ground.
3. Extend the rear jacks. The lights in buttons (C) light up to indicate that
the jacks have reached the ground.
When you stop drilling or using the utility boom, the order is reversed, i.e.
first raise the rear jacks, then raise the front jacks, and then retract the jack
beam. The lights (A), (B) and (C) go out to indicate that the jack beam and
the jacks are in transport position.

4.5.5 Emergency situation with utility boom

In an emergency situation, when the control place must be changed from


the basket to the operator station, use the spare key (1) located in the
operator station.

4.5.6 Working at extreme conditions


• When the boom is used at low temperatures, the oil in boom must be
warmed up at the same time the jumbo’s hydraulics is warmed up to
prevent thermal shock. Thermal shock may also occur when oil in boom
hydraulic system has cooled (e.g. during driving a long distance between
work sites) and hot oil from vehicle hydraulics is led to boom. Thermal
shock may damage the hydraulics.
• Lowest recommended working temperature for boom is -20 °C.
• Note that working under low temperatures accelerates hydraulic seals
wear and increases hydraulic hoses exposure to damages and steel
constructions exposure to brittle fracture.
• When working under lower than -15 °C it is recommended to lift lighter
loads than usual.
• Before starting working under cold conditions let the oil circulate freely
through system a few minutes.
• Slowly drive every movement several times so that the seals get liable
before they receive any full pressure.
• At exceptionally warm conditions, beware of the hydraulic oil overheating.
Too high oil temperature (> 80 °C) degrades oil and damages seals.

4.6 Using drilling controls


4.6.1 Safety instructions
Before starting the drilling, always conduct a visual check of the drilling site.
Scaling should be done as necessary.

DANGER
EXPLOSION HAZARD!
Drilling into unexploded charge will cause death or severe injury.
Drilling is forbidden if any part of the drilling face is charged.
Simultaneous drilling and charging is strictly forbidden.

WARNING
OIL MIST HAZARD!
Inhalation of oil mist could cause severe injury.
Shank lubrication oil may evaporate into the air during and after
drilling causing invisible oil mist which is harmful to health.
Wear approved respirator to avoid inhalation of oil mist.

WARNING
CRUSHING HAZARD!
Machine movements could cause severe injury or death.
Before moving the boom or commencing drilling, make sure there
are no unauthorized persons in the danger area.
When moving the boom(s), make sure that it does not hit anything.

WARNING! PERSONAL INJURY HAZARD!


Impact by drill steel could cause death or severe injury.
Do not leave the drill steel string unsupported in an upward hole!

PROPERTY DAMAGE RISK!


Inadequate operation of the shank lubrication quickly causes serious
NOTICE damage on the rock drill and difficulties during drill steel uncoupling.
Always check the oil level in the reservoir and the proper function of
the pump unit before starting a shift.

Always make sure that the shank lubrication oil you use meets the
specifications. Choose correct oil viscosity according to ambient
temperature.

4.6.2 Principles of percussion drilling

Percussion drilling has four main functions:


• Percussion (P), which makes the drill bit
penetrate the rock.
• Feed (F), which keeps the drill bit in tight A
contact with the rock.
• Rotation (R), which turns the drill bit to a
new position before the next percussion.
• Flushing (A), which removes the cuttings
and cools the drilling equipment.
The percussion energy created by the rock
drill piston is transferred to the rock through
the drilling equipment.

Copyright © Sandvik 231 (334)


ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

Percussion

Percussion refers to the rock drill piston's im-


pacting, reciprocating movement generated by
the hydraulics. The rock drill's shank transfers
the piston's percussion energy into the drill
rod, and the rod does the same through the
drill bit to the rock. The striking point is the
point where the piston hits the shank.
The percussion power is generated by the per-
cussion force, the percussion frequency, and
the drill bit’s penetration. The percussion pow-
er is conveyed to the rock through the drilling
equipment. The percussion power can be di-
rectly controlled by using percussion pressure.
One of the basic issues in drilling is the energy
transfer capacity of the drilling equipment. On-
ly a certain maximum amount of kinetic energy
can be transferred using drilling equipment of
a certain size. When the equipment’s ability to
transfer energy is exceeded, equipment dam-
age increases rapidly.
The percussion power used depends on the
quality of the rock to be drilled. If the rock is
soft, a lower percussion pressure can be used.
If the rock is hard, a higher percussion pres-
sure is used.
Setting the percussion pressure always in-
volves a compromise between penetration rate
and equipment durability.

ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

Feed

The feed movement means the rock drill's line-


ar movement on the feed.
The purpose of the feed is to keep the shank
tightly connected to the rock drill and the drill
bit in firm contact with the rock.
When the percussion pressure is increased,
the feed pressure must also be increased. The
correct feed power depends on the percussion
pressure, rock conditions, hole depth, and the
size and type of the drilling equipment.
Broken rock should be drilled using low per-
cussion pressure and low feed pressure.
The correct feed pressure can be determined
by observing and listening.
OBSERVE the following, which should be
present:
• Constant progressive movement of the
rock drill (the drill carriage should not
shake)
• Constant rotation of the rock drill (constant
rpm)
• Tight shank connection (the connection
must not overheat / turn blue / emit smoke)
• Constant penetration
LISTEN for the following:
• Constant drilling sound (no rattling or shak-
ing sounds)
Excessive feed power does not increase pene-
tration. It only increases drill bit wear, causes
irregularity in the drilled holes, and bends the
rod, causing unusually high rotation pressures.
Inadequate feed power leads to loss of contact
between the drill bit and the rock. This causes
the percussion energy to be reflected back to
the drilling equipment, causing damage to the
equipment, the rock drill, and the drill carriage.

ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

Rotation

Rotation is the drill rod's rotation movement


that aims to move the drill bit buttons between
percussions. The hydraulic motor inside the
rock drill rotates the drill rod through a gearing.
The correct rotation speed depends on the
form and diameter of the drill bit, hole depth,
rock conditions, and the other main functions
of drilling.
Inadequate rotation speed causes energy loss
(the cuttings are ground too finely) and leads
to poor penetration.
Too high a rotation speed results in excessive
bit wear, since the rock is broken by rotation
rather than percussion. Excessive rotation
speed also leads to overtightening of threaded
connections.

ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

Flushing

Flushing means transferring the loose rock


material (cuttings) created in drilling away from
the drill hole. The other task of the flushing
function is to cool the structures of the rock
drill and the drilling equipment.
Poor flushing leads to low penetration (cuttings
are ground at the bottom of the hole), to short
drilling equipment service life (risk of rod jam-
ming is increased), and to rapid wear of the
drill bit.
Water flushing
Water flushing is a flushing method that binds
rock dust. Flushing is led to the rock drill's
flushing housing, from which it flows through
the shank to the drill rod, and onward through
the flushing holes in the drill bit to the drill hole.
Air flushing
The flushing air is carried to the bottom of the
hole through the rod hole and the holes in the
drill bit. The mix of flushing air and cuttings is
directed out of the hole through the space be-
tween the rod and the hole wall.
Water mist flushing (optional)
In water mist flushing, a certain amount of wa-
ter is sprayed into the flushing air. The amount
of water is adjusted according to the hole size,
drilling direction, and rock type.

4.6.3 Drill steel

Shank

Impact energy and rotation torque of rock drill


are transferred to drilling equipment through the
shank.

Coupling sleeve

Coupling sleeves connect extension rods to one


another.

Extension rods
Both ends of an extension rod have identical
threads. Rod length is usually 10...18 ft.
(300...540 cm).

MF rods

MF rods have a male thread in one end and a


female thread in the other. Rod lengths are the
same as for extension rods.

Guide tubes

Guide tubes minimize hole deviations.

Drill bits

Button bit is the most common drill bit type. Its


advantages are good penetration rate, durabili-
ty, and easy re-sharpening.
Various types of button bits are available for dif-
ferent drilling conditions.

Example of the use of different drilling equipment


Guide tube and special bit is used when straight holes are required and the
drilling conditions are difficult.

4.6.8 Collaring

18 19 20

Drilling is started by locking the levers of the rotation (18) and percussion
(19) into the back position. When the lever for the feed (20) is pulled
backwards, the rock drill moves at the desired speed until the drill bit has
sufficiently penetrated the rock.
Full-power drilling is started by locking the control lever for the feed (20)
into the fully back position.

Another method for collaring

24
18 19 20

With standard system: Turn the feed force regulating knob (24) fully open
(counterclockwise) and then lock all three control levers (18, 19 and 20)
into the back position. Drilling starts now with half power and continues so

4.6.9 Reaming
When reaming holes, the drilling parameters and performance of the drilling
must be changed.
Before start to reaming:

21

24

With standard system: Decrease drilling force by turning the feed force
regulating knob (24) and rotating speed regulating knob (21)
counterclockwise.

21

24

With constant feed speed option: Decrease drilling force by turning the
feed speed regulating knob (24) and rotating speed regulating knob (21)
counterclockwise.

Especially, when reaming fissured rock or holes which have been directed
downwards flush the hole a few times during drilling.
WARNING! FLYING MATERIAL HAZARD!
Flying material could cause severe personal injury or property
damage.
Do not use air flushing with reaming bit. Flushing air will pressurize
between mud and drill bit. When block opens, material will blast out
of hole with unpredictable force.

4.6.10 Anti-jamming automatics


The anti-jamming system operates in a situation where the rotation
pressure of the drill rod rises above a set value due to, for instance, a
fissure in the rock.

The drilling system measures the rotation pressure of the rock drill during
drilling. If the pressure exceeds the limit value set with the anti-jamming
automatics, feed starts moving backwards.

When anti-jamming automatics starts, feed direction reverses automatically


and percussion remains on. When rotation pressure is again below the limit
value, the original feed direction is returned after a delay. At the same time,
drilling power drops to half-power level.

The feed and percussion pressures return to their normal set values as the
feed resistance rises normal.
The activation pressure of the anti-jamming automatics can be adjusted
according to rock type. The adjusting has been described in a instruction:
“Drilling hydraulics“.

Flushing flow control (optional)


When the water or air flow in the flushing circuit drops below the set value
of the flow switch (for example, due to lack of water or blocked drill bit), the
anti-jamming valve of flushing control is activated. Feed starts pulling
backwards until the water or air flow is normal.

4.6.11 Threading
During threading, rotation pressure must be kept below the anti-jamming
activation pressure. If the pressure rises to this value, feed direction is
reversed.
Threading means a situation where the drill rod is threaded on or off with a
rock drill shank or another rod. Threading is done with the control levers for
the rotation control lever (18) and the feed control lever (20).

Threading on

21

18

Rotation is turned on by pulling back the control lever of the rotation (18).
If required, the speed of rotation can be adjusted with the rotation speed
control knob (21).

24
20

With standard system: Pull the control lever of the feed (20) backwards to
feed the rock drill forwards at a speed that corresponds to the thread pitch.
Keep the feed speed constant throughout the threading operation.
Drilling power can be adjusted with the feed force regulating knob (24)
(normal feed pressure for drilling can be used as the basic setting).

With constant feed speed option: Pull the control lever of the fast feed
(23) backwards to feed the rock drill forwards at a speed that corresponds
to the thread pitch. Keep the feed speed constant throughout the threading
operation.

Threading off
With standard system: To thread off the drill rod-rock drill –connection,
turn on the rotation clockwise by pushing the control lever (18) forward, and
the rock drill feed backwards by pushing the control lever (20) forwards.
With constant feed speed option: To thread off the drill rod-rock drill –
connection, turn on the rotation clockwise by pushing the control lever (18)
forward, and the rock drill fast feed backwards by pushing the fast feed
control lever (23) forwards.
4.6.12 Flushing control
The drilling system is equipped with a function for separate flushing. This
makes it possible to flush the drilled hole with air or water as a separate
function after the actual drilling.

22

The selector valve (22) for separate flushing can be locked, so that flushing
can be left on for longer periods. When the separate flushing selector valve
is locked into the rear position, water flushing is turned on, while the front
position is for air flushing.

WARNING! FLYING MATERIAL HAZARD!


Flying material can cause death or severe injury.
Rocks can fly from the hole at high speed during air blowing. Always
use appropriate protective equipment.

4.6.13 Some drilling tips


The economy and the efficiency of the jumbo are highly depending on the
way how the operator is using the drill rig during drilling.
• Plan the drilling sequence so that drilling time for each boom is approx.
the same.
• If possible, position the feed so that the operator is able to see the drill
steel during drilling.
• Use always feed extension cylinder to push the feed rail against the rock.

• Before starting to drill and during the drilling make sure that the buffer in
the front end of the feed rail is firmly against the rock.
• During collaring the bit has a tendency to deviate from the given
direction. To overcome this situation, a lower drilling settings and long
enough collaring time should be used. If the hole deviates anyway,
direction of the feed rail has to be corrected according to hole direction.
Misalignment causes extra stresses and wear of the drill steel, wear
pieces, rock drill etc.

• Rotation pressure gauge is good guideline to find suitable feed and


percussion pressures. Normally pressure should be approx. 90...120 bar.
If it is higher or the drill bit is jamming continuously, check the condition of
the drill bit or lower feed and percussion pressures.
• Too low feed pressure causes poor penetration and rapid wear of rock
drill and the drill steels. Too high feed pressure causes also rapid wear
but also deviation of the holes.
• To ensure proper flushing observe that water is continuously running out
from the hole to be drilled.

ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

• During drilling the contour holes, avoid the rock drill, middle centralizer or
hose reel to touch the rock in order to avoid underfeeding and
mechanical damages.
• Avoid drilling above another boom because of falling rocks.

• Vibration of the rock drill hoses may mean that the diaphragm of the rock
drill low pressure accumulator is damaged or filling pressure is incorrect.
• Permanent drop of the penetration rate maymean that the diaphragm of
the rock drill high pressure accumulator is damaged, bit is worn out or
damaged.
• Change the drill bits often enough.
• In order to have the hydraulic parallelism system working, the extra tilt
cylinder of feed (bolting) must be completely in.

4.6.14 Drilling parameters


The relation between percussion pressure, feed pressure, rotation speed
and required flushing flow as well as their correct setting depend on several
factors such as rock conditions, bit type and the hole diameter.
Drilling parameters must be adjusted according to current drilling
conditions. Following table presents drilling parameters which are used for
factory test drilling in homogenous granodiorite.
Table in chapter "Recognizing incorrect drilling parameters" can be used as
a guideline to adjust proper parameters for current drilling conditions.
Following table shows example parameters for normal drilling with 9 button,
Ø 45 mm bit, HLX5 rock drill and TF-feed.

Recognizing incorrect drilling parameters

FAULT SYMPTOMS
• Drill bit wear
Too high percussion pres-
PERCUSSION • Shortened life of rock drill and drilling tools
sure
• Increased risk of drill rod sticking.
• Decreased penetration rate. (When drilling
into soft rock, the best penetration rate and
Too low percussion pres-
PERCUSSION longest drilling equipment life is reached
sure
with lower percussion pressure than when
drilling hard rock.)
• Fast wear of outer edge of drill bit (risk of
anti-tapered bit).
ROTATION Too high rotation speed • Fine-grained drill cuttings.
• Wear of rock drill and rotation mechanism
components.
• Uneven rotation of drill rod.
• Decreased penetration rate.
ROTATION Too low rotation speed
• Higher stresses on drill rod and rotation
mechanism.
• Sticking rotation (rotation pressure fluctu-
ates)
• Increased rotation torque (rotation pressure
rises), causing overload on drilling equip-
ment and rotation mechanism of rock drill.
NOTE! Increase in rotation pressure can al-
so be caused by drill rod bending or other
FEED Too high feed force abnormal resistance to rotation.
• Bending of drill rod, faster wear of centraliz-
ers and chuck, increased risk of piston strik-
ing shank at an angle.
• Changed sound of rock drill.
• NOTE! INCREASING THE FEED FORCE
OVER A CERTAIN LIMIT DOES NOT IN-
CREASE PENETRATION RATE.

• Rock drill jumps and shakes (clinking sound)
• Front end of chuck and coupling sleeve of
drill rod wear faster.
• Faces of rock drill body will wear faster
(maintenance intervals are shortened).
FEED Too low feed force • Penetration rate decreases. The shank is
not in correct position when piston strikes.
Only a small proportion of impact force is
transmitted to rock.
• Life of drilling equipment is shortened (great
tensile stresses on drilling equipment).
• Increased risk of jamming.
• Drill bit wears fast (overheating)
FLUSHING Too low flushing pressure
• Lower penetration rate.
• Fine-grained drill cuttings.
• Drill bit wear increases
FLUSHING Too high flushing pressure • Poor life time of the flushing housing seal

4.6.15 During drilling


Observe during drilling:
• The operation of shank lubrication.
• Oil mist comes out from the openings at the bottom of the rock drill's
body
• The rock drill hoses are not shaking more than usual.
• The rock drill shows no oil leaks.
• The rock drill flushing housing seals are not leaking water.
• No hose connections are leaking.
• The drilling pressure gauges show normal readings.
• No yellow or red warning lights are on.

4.6.16 After drilling


1. Loosen the bit and rod. See chapters Changing the drill bit (Page 257)
and Removing a jammed rod (Page 255).
2. Blow water out from the water circuit. Blow anti-freeze into the circuit, if
necessary.
3. Move the booms, the feeds and cabin/canopy to the driving position.
4. Raise the jacks.
5. Stop the power pack(s).
6. Disconnect the power from the main switch.
7. Start the diesel engine and select cable and water hose reeling.
8. During tramming observe that reeling is operating and the booms are not
colliding with the walls.
9. Disconnect cable and water hose and their anchors. Make sure that they
do not drag on the ground during tramming.
10. Tram to the service area and perform shift and daily service to the drill
rig.
11. If the drill rig is left unattended, the battery isolation switch has to be
switched off.

WARNING! UNCONTROLLED MOVEMENT HAZARD!


Uncontrolled drill rig movement could result in death or severe
injury.
Whenever the drill rig is parked, the jacks must be down and the
parking brake applied.

4.6.17 Special situations

Removing a jammed rod


Depending of rock conditions, the drill bit may jam. If bit is jamming
continuously in normal conditions, some drilling parameters may be
incorrect or bit is worn or damaged.
If the bit is not jammed very tight, there is a good possibility to get it out. Try
the following methods:
1. Turn the water flushing on.
2. Select full percussion.
3. Select feed backwards.
4. Try to rotate on both directions.

WARNING! PERSONAL INJURY HAZARD!


Impact by tensioned boom or drill steel could cause death or severe
injury.
If you must cut the drill steel or detach it from the feed, make sure
that neither the drill steel nor any part of the boom is under stress.
When the drill steel is cut, the steel or the feed may strike an
unexpected blow.

Do not use boom or feed movements for loosening drill rod.


NOTICE
Disturbance in shank lubrication

The SLU unit monitors the oil flow. If no flow is detected, the indicator light
(H72) on the drilling panel comes on and automatic drilling is stopped. This
is reset by restarting the percussion or rotation and testing whether
lubrication starts.
In the shank lubrication system, the air pressure for shank lubrication is
also monitored, separately for each rock drill. If the air pressure falls below
2.8 bar, the indicator light (H72) on the drilling panel comes on and
automatic drilling is stopped.
The oil level in the SLU oil tank is monitored as well. If the oil level in the
SLU oil tank drops below the preset minimum level, all power packs are
stopped and the low shank lubrication oil level indicator light (H608) on the
QN panel comes on.

ID: BG00810000 en-US A.001.1 2017-03-24
Operator's Manual DT621

Too low or high stabilizer pressure

The stabilizer pressure control system monitors for insufficient or excessive


pressure. The control has a two-second delay.
The stabilizer pressure control is activated when the power pack of the
boom in question is started. If a stabilizer pressure fault occurs, the
stabilizer indicator light (H72) on the drilling panel starts to flash and
automatic drilling is stopped.
The stabilizer pressure control has no separate reset procedure; drilling can
be continued as soon as the stabilizer pressure is within the permissible
range.

Drilling bolt holes

• When drilling bolting fans, turn bolting joint 90° and use boom head
rotation to move from the hole to another.

• Always use the feed extension cylinder to push the feed rail against the
rock. Do not use boom lift, boom swing or boom extension to push the
feed rail against the rock.
• When drilling upwards, higher feed force has to be used to eliminate
under feed.

Changing the drill bit

DANGER
ENTANGLEMENT HAZARD!
Getting entangled in rotating parts will cause death or severe injury.
Do not enter the hazard zone when the rotation is on.

The bit should be sharpened in fixed intervals to get good


NOTICE productivity and low drilling cost.

• Replace the drill bit if its buttons are worn (1/3 of the button is worn flat).

Do not wear down the drill bits completely. Replace the bit at the
NOTICE latest when 1/3 of the button is worn flat.

• Tram the drill bit against a rock. Start the water flushing and percussion.
Use percussion and feed to hammer the drill bit against the rock until it
comes off (water runs from between the bit and the tube/rod).
WARNING! HIGH-PRESSURE FLUID INJECTION HAZARD!
Water spray from the drill bit flushing holes or between the threads
can cause injuries.
Always wear the necessary protective equipment.

WARNING! HAZARD DUE TO FLYING ROCK PIECES!


Flying rock pieces can cause severe injury.
Always wear appropriate protective equipment.

• Turn the drilling module into such a position that the bit can be easily
removed and replaced with a new or sharpened bit.
• Enter the boom area to change the bit.

WARNING! BURN HAZARD!


The hot surfaces of the drilling equipment could cause burns.
Let the drilling equipment cool down before touching it. Always wear
protective gloves when handling drilling equipment.

4.6.18 Ending a shift


• Always when you stop drilling at the end of your shift, for a lunch break,
to move the drill rig, or for some other reason, blow the rock drill and the
drill steel clear of water using air flushing.
• Run the front end of the feed downwards, so that water would come out
from inside the feed.
• Wash the drill rig before the end of your shift (boom and the drilling
module).
• Report any faults or defects that you noticed to the personnel of the next
shift.
• Stop the power pack.
• Close the water valve located at the rear of the drill rig.
• Turn the product main switch into 0-position.
• Turn the battery isolation switch to the OFF-position.
Note! DANGER OF FREEZING OF THE WATER CIRCUIT! If the air
temperature is below 0 °C and drilling is to be stopped for a long
period, drain the water circuit completely and fill with anti-freeze
agent.

Note! If the break is longer than just between shifts, drive the drill rig into a
dry place.

5.15.2 Cleaning the mud separator


Note! The mud separator does not operate effectively if it reuses water
already used for flushing.

Restricted water flow causes flushing and cooling problems. The most
common reason for the drop of pressure is a blocked mud separator. This
is why the separator must be cleaned every day. If the conditions change,
start by cleaning the separator more often and determine the correct
cleaning interval based on experience.

Cleaning procedure:
1. Open the shut-off valve (1).
2. Open the drain valve (3) of the mud separator (2) enough to allow the dirt
in the strainer (4) to come out.
3. Close the drain valve (3) of the mud separator.
4. If no dirt comes out, change or clean the strainer (4).

Drill rig
• Wash the drill rig if it has been in use or has been transported by sea.
Use a high-pressure steam washer.
• Empty the water circuit and blow some anti-freeze agent into it (an
anticorrosive agent).
• Lubricate the drill rig (all greasing points).
• Lift the drill rig with the jacks (if the drill rig is equipped with jacks).
• Tilt the feed's front end downward.
• Empty the rock drill's pressure accumulators and prominently hang a sign
informing other personnel of this (the pressure accumulators must be
filled before the drilling rig is used).
• Protect all hydraulic cylinder piston rods with grease.
• Empty the water separator.
• Replace all lubricants and fluids, which may have deteriorated in use.
• Protect all electrical devices from corrosion so that there will be no
contact failures.
RISK OF DAMAGING THE DRILL RIG!
Too high a humidity level in the storage location could damage the
drill rig.
Ensure that the storage space does not collect water, that the
NOTICE humidity will not become too high, and that the location is otherwise
protected from the elements.
Protect the electrical connections in accordance with the
instructions set: “Protecting electrical and electronic components
and connectors with protective agents”.

Proceed as specified in instructions set, and use a suitable protective agent


to protect, for example, the following points:
• coupling box connections
• screw terminals of the multi-pole switches
• battery terminals
• multi-pole switch coupling contacts
• contacts of the connecting caps of magnetic valves, pressure switches,
and corresponding parts (fill the caps with grease)

6.6 Washing

WARNING
HIGH PRESSURE FLUID HAZARD!
High pressure fluid spray could cause severe injury.
Never point the nozzle on anybody. Use eye-protector.

Before washing the drill rig with water, high-pressure cleaner, steam
cleaner, or any other method, protect any components that are susceptible
to damage from the cleaning method or due to exposure to water. Pay
special attention to the protection of electric motors, boxes, and cabinets.
Before washing cylinders, protect load control valve breathers. Painted
surfaces of the cylinders can be washed as any other painted surface
(pressure/steam cleaner), but do not spray the water/steam directly into the
piston rods. Detergents and hot water/steam will destroy waxing which is
essential for the functioning of the cylinders. After washing, the rods must
be protected with oil by either wiping oil onto the piston rods or by
extracting and detracting the cylinders.
In addition to washing the drilling module and the front part of the machine
daily, the complete machine should be washed according to the interval
stated in the maintenance cards in the maintenance manual or at least
once a week. The washing interval should be adjusted to surrounding
conditions, i.e. in a dirty environment the complete machine can be washed
more frequently. Accumulated debris on the machine structures promotes
corrosion and component wear.

Pressure cleaning system with reel (optional)

Water starts to flow when the washing nozzle is turned open. The washer
functions at water distribution system pressure. Washing pressure can be
seen from the pressure gauge connected to the cleaner. The normal water
pressure is 5...20 bar. Stop the washer by turning the nozzle.

High pressure cleaning system with reel (optional)

The high pressure cleaner is hydraulically operated. The high pressure


washing can be started by pulling the handle of the washing pistol. The
pump starts to idle.
The water flow is controlled by the handle of the washing pistol. The
washing pressure can be seen from the pressure gauge connected to the
cleaner. The normal water pressure is 140...170 bar.
