and take the necessary measures to prevent acci-
dents.

Safety precautions and recommendations are

outlined in this section and are also included in the
operation and maintenance instructions given in
subsequent sections. Warning labels are also
provided on the crane.
The cautionary instructions in this manual are
identified as “DANGER”, “WARNING”, “CAUTION”
or “NOTICE”. These terms are defined as follows:

DANGER indicates an imminently hazardous

situation, which, if not avoided, will result in death
or serious injury.

WARNING indicates a potentially hazardous

situation, which, if not avoided, could result in
death or serious injury.

CAUTION indicates a potentially hazardous sit-

uation, which, if not avoided, may result in a minor
or moderate injury.

[NOTICE]
GR-300EX-1/O1-1E

◆NOTICE indicates an important operational or

maintenance procedure or condition, which, if not
strictly observed, can result in damage to machine
components or deteriorated machine performance.

Avoid Careless Swinging

Carelessly swinging a load lifted from the over-front
area to an over-side area, where crane stability is
lower, may overturn the machine. Before swinging,
be sure that weight of the load is less than the 360°
capacity.

Carefully Swing a Load

When swinging a load, the tilt of the machine may
vary.
Listing of the machine is greatest when the load is
lifted on an over-side area. As a result, the working
radius will be higher, and the machine may become
overloaded and overturn.
Swing the load cautiously while controlling the in-
crease in working radius.

the same settings for the boom length, boom
angle, and number of rope parts.
• Lift the load so that the wire rope(s) of each crane
are only subjected to vertical line pulls.
• Attempt to rig the load so that all the cranes are
loaded equally.
• To move the load, use only the winches and
booms. Swinging operations should be avoided.
Do not perform hoisting, elevating (or telescoping)
of the boom or swinging at the same time.

Keep Away from Moving Parts

Inadvertent motion of the machine, or contacting a
moving part can cause personal injury and even
death.
When necessary to inspect or maintain the machine
while running, do not approach moving parts such
as the boom, hoisting cylinder, winch, fan, fan belt, T00044
and propeller shaft, etc.
Keep hands and clothing away from moving parts.
Lock the Inspection Hole Covers
An inspection hole cover that remains open can be
closed abruptly by a gust, etc., causing hands or a
leg to be caught and injured.
If an inspection hole cover or access door, or the
operator’s cab door must remain open, secure in
position.

Do Not Allow Tools and Parts to Drop

T00046
When working through an inspection hole while fac-
ing down, be careful not to drop objects into the
hole. Such mistakes can damage or lead to malfunc-
tion of the machine. Do not keep objects which are
not needed for inspection in open pockets.
Recover any object or tool that has dropped into the
machine.

Beware of Oil Smears

Oil smears on the clutch, lining and brake disks can
decrease braking effectiveness. Always keep these
assemblies free from oil accumulation.

Operating Gearshift Lever while Traveling

Do not travel with the gearshift in “N” position.

This will cause transmission seizure, excess
speeding, etc. to cause a serious trouble.

[NOTICE]
◆Shifting from First, Second, Third or Drive into
Reverse, or from Reverse into First, Second, Third
or Drive while traveling may damage the transmis-
sion. Be sure to stop the vehicle before shifting into
or out of Reverse.

The gears can be shifted manually while traveling. Shift

into First gear to start traveling and then change to
Second gear, Third gear and then Drive to speed up.
When ascending a grade while manually shifting gears,
choose the proper gear to climb the grade.
When accelerating while manually shifting gears, accel-
erate until the traveling speed reaches the next higher
range. Then shift to the next higher gear. When deceler-
ating, slow down to the next slower range and then gear
down.
◆Shifting into Third, Second or First gear at high
speeds activates the safety device for engine protection,
which prevents the gear from shifting down until a safe
traveling speed is reached. Before shifting to a lower
gear, slow down using the foot brake.

Abrupt braking not only damages the tires and
brake system, but also causes the vehicle to skid
on a slippery road surface. Avoid abrupt braking.
Excessive use of the service brake pedal can
overheat the brake discs and brake pads leading
to a decrease in brake performance or "brake
fade" which can cause the brake to become inop-
erable.
When traveling down a long grade, shift down to
the proper speed range to activate engine braking
and use the exhaust brake as supplement. Slowly
pump the service brake pedal to effectively slow
down.
When the brake warning lamp goes on during
travel, there may be external leakage of brake fluid
or wear of disc brake pad. Stop the carrier immedi-
ately and check for fluid leaks and pad wear.

For healthy air conditioning, the optimum condi-
tion is to provide a 5–8°C temperature difference
from the ambient temperature. Adjust the room
temperature so that it is not excessively lowered
and the operator is not exposed to cold air for a
long time.
◆Ventilation:
The air inside the cab becomes dry due to the air
conditioner’s dehumidifying effect. During smok-
ing, open the window for a while to ventilate the
cab.

Single Top Lift When Outriggers are not

Extended (On-rubber)
For operations with the single top mounted, use the
boom lift and on-rubber section of the rated lifting capac-
ity table to find the allowable load. Find the rated lifting
capacity value based on boom length and load radius.
From that value, subtract mass of hook (for 30-ton ca-
pacity : 270kg, for 20-ton capacity : 220kg). The
resultant value is the rated lifting capacity for a single
top lift. However, remember that the maximum rated lift-
ing capacity for a single top operation is 39.2kN (4,000
kg). When the result of the above calculation (<table val-
ue> - <mass of hook>) is over 39.2kN (4,000 kg),
always regard the rated lifting capacity as 39.2kN (4,000
kg).

• When the crane is automatically stopped during

a critical operation (hoisting up, boom exten-
sion or boom lowering), operate the appropriate
controls to move toward the non-critical condi-
tion (hoist down, retract boom or raise boom).
• Do not elevate the boom to raise the load clear
of the ground. Doing so is dangerous because
the crane will not stop automatically even when
it is overloaded. Hoist up the load to raise it
clear of the ground. Once the load has cleared
the ground, stop hoisting and check for safety.

Selecting Jib Mounted Condition

If the jib mounting/dismounting state is set im-

properly, the AML can not detect the actual load
precisely. The crane operation in this condition
could create hazard.

The jib can be dismounted from the crane body when it

is not used. The reduced mass of the crane body after
jib removal will influence the precision of the AML. Use
this switch to set the jib mounting /dismounting state to
the AML.
◆The key can be inserted in/removed from either
“REMOVED” or EQUIPPED” position.

(1) “REMOVED”: Select this position when the jib is dis-

mounted. The jib removed indicator lamp will light up.
(2) “EQUIPPED”: Select this position when the jib is
mounted. The jib removed indicator lamp will go off.

Warming Up the Machine

[NOTICE]
◆Be sure to allow the machine to warm up before
the start of any operation. This practice is especially
important in cold weather when the engine and hy-
draulic oil viscosities are high. If an operation is
started without sufficiently warming up the engine
and machine, highly viscous oils may cause dam-
age to the engine and hydraulic system.

1. Let the engine warm up at idling speed for approxi-

mately five minutes after starting the engine. When it is
very cold, extend the warmup time as necessary, ac-
cording to the ambient temperature.

2. Lock the suspension to lower the frame fully.

3. Engage the PTO and extend the outriggers.

4. Increase the engine speed to between 800 and

1,000 r/min [rpm] and operate the crane without a load
for approximately five to ten minutes. When it is very
cold, extend the operating time according to the ambient
temperature.
◆Check the engine, hydraulic pumps, hydraulic motors,
swing bearing and each pivot pin for any unusual sound.
If any are found, stop operation immediately and contact
the nearest TADANO distributor or dealer.

5. Only start a lift operation after the machine has

been sufficiently warmed up without a load.

Setting the Crane

If the crane is set on inappropriate ground, it is

possible that the crane could overturn. Always set
the crane on firm ground.

Preparing the Ground

When setting the crane on soft ground or on ground that
cannot bear the weight of the crane, carry out the follow-
ing procedures:
(1) Grade a slope or rough surface so that the crane can
be set in a level position.
(2) Place steel plates or wood blocks on the surfaces
where the outrigger floats are to be located, in order
to distribute the ground bearing pressure over a larg-
er area. The steel plates and wood blocks must be
sufficiently strong and large in area and also appro-
priate for the ground condition. The outrigger floats
must be set at the center of the plates or blocks.

This method of telescoping the boom should be used to

stow the boom when the boom cannot be extended or
retracted for some reason, such as a malfunctioning
boom length sensor.

Use this procedure also when you need to extend or re-

tract a boom section in a sequence other than the
normal sequence, for inspection or maintenance purpos-
es.
The controls used in the emergency telescoping proce-
dure are the boom telescoping /auxiliary hoist control

Swing Stop

Remember that swing stop function does

not work during on-rubber operation.

[NOTICE]
◆The swing stop function works only while the fol-
lowing conditions are satisfied:
• The crane is set level.
• A load does not sway while the boom is swung.
• There is no or weak wind blowing.
◆If a load moment in a stationary state is between
90% and 100% of the limit, there is a possibility that
the swing operation is automatically stopped
because the moment exceeds 100% due to an added
moment by sway of the load or centrifugal force
during swing motion. In this case a message of
"Warning: 0042" or "Warning: 0043".

This function automatically halts the boom swing under

the following two conditions. While this function is acti-
vated, the boom swing speed gradually decreases to
stop before the boom reaches the stoppage position.
(1) The right and left outrigger extension widths differ
and further boom swing will lead to overloading.
(2) Boom swing limit is registered on the AML.

Reeving Wire Rope

Standard Number of Parts of Line

If the wire rope is reeved in a number of parts of

line greater than the standard and the boom is
raised to a large angle, the extra wraps of rope
that should be left on the drum will be unwound
before the hook block reaches the ground, caus-
ing damage to the wire rope and its anchor at the
winch drum. Even with the standard number of
parts of line, this problem will arise if the load is
lowered below ground level. When the number of
parts of line is greater than the standard or the
load is being handled on a site that has a signifi-
cant elevation differences, ensure that more than
three wraps of rope will remain on the winch drum
while the load is lowered.
When the number of parts of line is less than the
standard, be sure not to exceed the allowable load
for one part of line. (See the "INFORMATION AND
DATA" section.)

The following table shows the standard number of parts

of line for different boom lengths. Select the number of
parts of line that ensures the most efficient operation,
taking into consideration boom length, load mass, hoist-
ing speed and other conditions such as winch drum wire
rope capacity.

Mounting the Jib 1. Set the crane on fully extended outriggers in a loca-
tion large enough for mounting the jib.

Do not lower the boom to an angle below 0°.

This action could cause the jib to disengage and
drop off.
Always make sure that both the stowing pin
and pivot pin are in position before starting any
operation. Without these pins in position, the jib
will drop off when an operation is started.

T00753

2. Take the auxiliary hook block out of stowage, and

place it below the expected position of the jib tip.

T00649-1

Take the necessary precautions to ensure that

nobody enters the area over which the jib will
swing. Anyone standing in this area could be in-
jured. Also check the adjacent work area for any
structure or other obstruction that may present a
problem when operating the jib.
The AML control functions and the automatic T23299

stop function are deactivated when the jib set sta-

tus is selected on the AML. Mount the jib carefully
with no load on the crane.
3. Select the jib set status on the AML.

When working at an elevated position, use a

Inspection and Maintenance

Proper inspection and maintenance helps ensure safety

and prolongs the life of your crane. To keep your crane
in peak condition and maintain optimum performance,
inspect and service it at the recommended intervals. In
this way, you can prevent failures and detect problems
in their early stages.
Two recommended inspection and maintenance inter-
vals are provided; one based on the hourmeter reading
and the other on calendar months; perform inspections
and maintenance according to whichever comes first.
◆The inspection intervals are based on the assumption
that the crane is used under normal operating condi-
tions. If it is used under severe or unusual conditions,
shorten the intervals accordingly.
◆If you are unable to perform any inspection or mainte-
nance work yourself, contact your nearest TADANO
distributor or dealer for assistance.

Pre-Operational and
Periodic Inspection

If pre-operational and periodic inspections are

neglected, it will not be possible to detect prob-
lems in their early stages or prevent consequent
accidents. Make it a habit to perform the recom-
mended pre-operational and periodic inspections.
If any abnormality is found, take corrective action
immediately.

Brake System

Using different brands of brake fluid together

can change the properties of the fluid and may
have an adverse effect on the brake system. For
brake fluid, use "TADANO Genuine Brake Fluid". If
another recommended brand must be used, drain
all of the remaining brake fluid before adding new
fluid.
"TADANO Genuine Brake Fluid" and other
recommended brake fluids are all glycol-based. If
a silicon- or mineral-based brake fluid is used, it
will permeate the packing causing the brakes to
become ineffective. Therefore, always use glycol-
based brake fluid.
Some low-grade glycol-based brake fluids have
a low boiling point. Using a low-grade brake fluid
is dangerous because it could result in vapor lock.
Use only "TADANO Genuine Brake Fluid" or an-
other recommended brand.
Over time, brake fluid gradually absorbs mois-
ture from the air, which lowers its boiling point.
This behavior could result in vapor lock. Be sure
to replace the brake fluid regularly.

Battery Electrolyte Check

・・・・・・・・・・・・・Every 300 Hours
or Every 3 Months

Using or charging the battery with its fluid lev-

el below the "LOWER LEVEL" line indicated on its
side may cause an explosion of the battery.
Always take care of the battery fluid level.
The hydrogen gas released from the battery is
explosive. Never use a cigarette lighter or other
open flame near the battery, particularly at the
battery vent openings. Use a flashlight for illumi-
nation when checking battery fluid level.
If battery fluid gets in your eyes, it may cause
blindness. Should this happen, immediately flush
your eyes with a large amount of water and seek
medical attention.
When removing batteries, set the starter switch
OFF; remove them from the ground side terminals
(-). To connect the terminals, begin with the posi-
tive (+) side . Take care to the terminal positions.

The fluid level should be between the "UPPER LEVEL"

and "LOWER LEVEL" lines. If the fluid level is low, add
battery fluid or distilled water to the "UPPER LEVEL"
line.

Standard specific gravity of the battery fluid is 1.27–1.29

(20°C).
Recharge the battery if it is smaller than 1.21.

After Replacing Wire Rope

◆A new wire rope is prone to improper winding. Check
the rope on the winch drum from time to time. If it is im-
properly wound, rewind it neatly.
◆When first using a new wire rope, lift light loads at low
speeds in order to settle the strands. This helps prolong
the life of the wire rope.

When the wire rope is replaced, the new wire rope

wound around the winch drum does not have the proper
tension. If a load is hoisted with the rope at improper
tension, the wraps in an outer rope layer will become
wedged between the wraps in an inner layer, possibly
deforming the wire rope, or causing improper winding,
broken wires, etc. Before actually lifting a load, apply the
proper tension to the wire rope and rewind as follows:

1. Extend the boom, and unwind the wire rope until

about three wraps are left on the winch drum.

2. Suspend a load to give tension to the wire rope

and then wind the rope tightly around the winch drum.
Use a load of the mass obtained by the following equa-
tion:
[Load of the mass]
=[Allowable load per line]x0.3x[Number of parts of line]
(For the allowable load per wire rope, see the "INFOR-
MATION AND DATA" part.)
