 Safety Regulations

2 Safety Regulations

This chapter summarises the most important safety regulations. This

chapter is, therefore, particularly suitable for an initial basic
instruction for new operators. Naturally, the various regulations are
also repeated once more at the appropriate points in the operating
instructions.

Note
Special safety regulations may be required for some tasks. These
special safety regulations will only be found in the description of the
particular task.

The following safety instructions should be regarded as supplements

to the existing national accident prevention regulations and laws.

Existing accident prevention regulations and laws must be observed

in all cases.

We include here a listing of regulations and safety standards for your

information:
– Machine Directive 98/37/EC
– EN 292, Safety of machinery,

 Safety Regulations

2.1 Principle Use high−pressure cleaners only as specified and in a technically

perfect condition. Avoid danger by observing safety factors and the
specifications in the operating instructions. Any faults, especially
those affecting safety must therefore be rectified immediately.

Make sure that:

− safety equipment is not removed, rendered inoperable or
modified.
− safety equipment removed for the purposes of maintenance work
is refitted immediately after the work is completed.

Check operational safety every time you start work. Any defects
found or suspected must be repaired immediately. If necessary,
inform the project supervisor. Cease work if defects are found that
could jeopardise operational safety.

Use only high−pressure hoses, water hoses and couplings, etc. from
the machine manufacturer that are in perfect condition and suitable
for cleaning tasks.

Onwards sale If you sell on the high−pressure cleaner you must observe the
following:

Pass on to the new operator all the accompanying documentation

(operating instructions, maintenance instructions, diagrams,
machine cards, inspection certificates etc.) you received with your
high−pr essure cleaner. If necessary, you may have to order the
papers from us, specifying the machine number .

Reporting an onwards sale or acquisition to Putzmeister ensures that

you will be sent any information relating to modifications or
innovations relevant to safety, and you will also be eligible for
technical consultancy from our works.

Instruct the new operator and his operating personnel in the

operation of the machine, just as you were instructed by us, and
have them confirm that they have received instruction from you.
Should you so require, we will be happy to carry out the instruction of
the new operator and the new operating personnel on your behalf.

 Safety Regulations

2.2 Designated use The machine has been built in accordance with the state of the art
and recognised safety rules. Nevertheless, its use may constitute a
fatal risk to the operator or third parties, or cause damage to the
machine and to other property.

The machine should only be used as specified in the operating

instructions and the accompanying documents. All instructions and
safety regulations in the operating instructions must be stringently
observed.

The machine is intended for cleaning with pressurised water and

serves as a unit for emergency operation of Putzmeister concrete
pumps for boom and support operation.
The DYNAJET mg supplies cold pressurised water at a maximum of
350 bar, depending on the model.
Cold, clean mains water should be supplied to the machine via the
low−pr essure hose. Other materials should not be used.

 Safety Regulations

2.3 Use contrary to the Use of the machine other than that described above, or which goes
designated use beyond such use, is considered contrary to the designated use.
Putzmeister Mörtelmaschinen GmbH accepts no liability for damage
resulting from such use. The machine operator bears full
responsibility for risks caused by misuse of this kind.

Exclusion of liability We state here expressly that Putzmeister Mörtelmaschinen accepts

no liability for damage arising from incorrect or negligent operation,
servicing or maintenance or as a result of use contrary to the
designated use. This statement is equally valid for modifications to,
additions to and customisation of the machine which may
compromise safety. The guarantee will no longer be valid in such
cases.

Modifications Never make any modifications, additions or conversions to the

machine which may affect safety without first obtaining the
manufacturer’s approval. This also applies to the installation and
adjustment of safety devices and valves as well as to welding work
on load−bearing elements.

In particular, this requirement refers to:

− adjustment of safety and control pressures, speeds of movement,
power outputs, speeds of rotation and other settings to values
other than those set in the works.

 Safety Regulations

2.4 Sources of danger Never reach into the moving parts of the machine, whether the
machine is running or switched off. Always switch off the main switch
first. Take note of the warning plate.

In the event of malfunctions, stop the machine immediately and

secure it. Have any faults rectified immediately.

Before starting up the machine, make sure that nobody is placed at

risk by the running machine.

Do not loosen or retighten pressurised screw connections.

Hot machine During and after completion of work, there is a danger of burns from
components hot parts on the drive motor.

When carrying out maintenance work, remember that the drive motor
and the exhaust may still be hot. Allow them to cool down first. Work
with protective gloves.

High-pressure gun A water jet is discharged from the high pressure gun at a maximum
pressure of 350bar, depending on the model. This presents a high
risk of injury.
When working with the high−pressure gun, wear your personal
protective equipment at all times.
Never direct the high−pressure jet at personnel.

The high pressure produces jet reaction forces. Make sure you have
a steady stance when working.

Safety equipment Never remove safety equipment or render it inoperable by modifying

the machine.
Safety equipment must only be repaired, adjusted or replaced by
technically qualified experts.

All equipment required for safety and accident prevention (warning

signs and information notices, cover grilles, covers, etc.) must be in
place. Such equipment must not be removed, modified or damaged.

Any safety devices removed for set−up, maintenance or repair

purposes must be refitted and checked immediately upon
completion of the maintenance and repair work.

2.5 Handling high-pres- It is essential that correct high−pressure hoses be carefully selected
sure hoses and handled correctly to maintain the operational safety of the
high−pr essure cleaner.
Observe the following rules when handling high−pressure hoses:
− High−pr essure hoses that are marked with a permissible operating
overpressure lower than the one specified in the technical
specifications or hoses that have no markings at all, should not be
used.
− High−pr essure hoses must be laid and secured in order to prevent
any danger should the hose lines burst.
− High−pr essure lines must consist of functioning hoses and
connections that are compatible with each other.
− High−pr essure hoses must not be painted.
− High−pr essure hoses should only be connected by specially
trained and qualified persons.
− Depressurise high−pressure hoses after operation.
− Do not crush high−pressure hoses or lay them over sharp edges.
Avoid tensile and bending loads.
− High−pr essure hoses must be stored free of kinks and tension.

High−pr essure hoses are wearing parts with a limited service life.
They should therefore be replaced at appropriate intervals according
to the operating conditions, even if there are no obvious external
defects.

The hoses must be replaced when the following defects occur:

− Scuff marks, cuts or cracks that pierce the outer layer and reach
through to the wire infill.
− Embrittlement of the outer layer (crack formation) due to improper
storage.
− Storage limit and usable service life have expired. As a reference
value, DIN specifies 6 years plus a maximum of 4 years previous
storage time for an unconnected hose.
− Leaks in the hose and at the connection point.

Never search for leaks in high−pressure hoses or pipes with your

bare hands. An escaping high−pressure jet may not be visible and
can cause serious injury.

 Safety Regulations

2.6 Injuries from Work with high−pressure water jets produces very high pressure that
high-pressure water acts over a relatively small surface area. This concentration of
jets energy is the reason why a high−pressure water jet may cause
serious injury.

If a high−pressure water jet makes contact with the skin, it can

penetrate the surface of the skin and damage the tissue underneath.
In addition, the water can inject foreign matter deep into the body
and cause dangerous infections. With injuries caused by
high−pr essure water jets, it is not possible to assess the extent of
damage to the tissue from the outside. Therefore, any injury caused
by a high−pressure water jet is regarded as an acute surgical
emergency and must be treated by a qualified orthopaedic surgeon.
Inform the acting doctor that the accident was caused by a
high−pr essure water jet.

2.7 Unauthorised use Always secure the machine against rolling away and unauthorised
use when you leave the workplace!

Always secure the machine against unauthorised starting before

leaving the work area. This means:
− Remove the ignition key

2.8 Personal protective The operator must provide personal protective equipment to be used
equipment by the operating personnel.

Provide and use personal protective equipment if necessary or if

required by regulations.

Personal protective equipment includes protective suits for the

high−pr essure area, a protective helmet with visor and ear
defenders, protective goggles, gloves and rubber safety boots.

clothing only provides protection from spray water and splash
particles.
In the case of direct contact with the high−pressure water jet,
protective equipment does not guarantee protection against injuries
caused by the high−pressure water jet.

Never direct the high−pressure jet at personnel to clean dirty

protective clothing still being worn.

A fan jet nozzle (1505) is included in the scope of delivery. It has a

spray angle of 15° and a nozzle size of 34.
Fan jet nozzles are characterised by a uniform fluid and pressure
distribution. The flow geometry of the nozzles creates a compact,
regulated jet. They can be used universally and are not sensitive to
pressure fluctuations.

Nozzle designations are composed as follows:

XX 0XX

Nozzle size
Spray angle

Note
Bear in mind that the nozzles have an influence on the water
pressure. If a nozzle is used and is too small, the pressure may
increase and trigger the unloader which limits the system pressure to
a maximum of 350 bar.
If the nozzle is too large, the pump may not be able to attain
maximum pressure at the full delivery rate.
The pressure decreases as the nozzle wears.

Danger
Use only nozzles approved by Putzmeister. Please note that the use
of other nozzles could lead to increased rebound pressure.

 Operation

6.4 Cleaning After completion of work, clean the machine and the delivery and
high−pr essure hoses. This ensures that the key components
continue to function correctly.

Environmental protection
During all cleaning work, observe the waste disposal regulations that
apply to your region.
Do not allow cleaning additives to enter the sewage system.

General Prior to cleaning the machine with a steam jet or high−pressure

cleaner, cover or seal all openings where moisture must not enter for
reasons of safety or relating to machine operation. Control cabinets
and electrical plug−in connections are especially at risk.

Do not allow water to enter the electrical systems

Note
In the first six weeks of operation, clean all painted surfaces with
cold water only at a maximum water pressure of 5 bar. Do not use
any aggressive cleaning additives. Only after this time will the paint
have hardened completely, allowing you to use steam jets or similar
tools.

 Faults, Cause and Remedy

7 Fauls, Cause and Remedy

This chapter gives you a summary of faults and their possible

causes, and also ways in which you may rectify them.
Observe the safety regulations when searching for a fault.
Only suitably trained technicians may work on the electrical system.

7.1 High-pressure cleaner The Dynajet 350 mg Plus high−pressure cleaner (with the other
with operating module Dynajets mg optional) is fitted with an operating module. Any faults
relating to the assigned parameters are displayed here.

If a switch changes status during operation, the motor is stopped

after 3 seconds. The time of faults < 3 seconds is added up and
stored.
If the stored value exceeds 3 seconds, the motor is also stopped.

If a fault does not occur again within 10 seconds, the memory is

deleted. The fault that occurs first is stored and all other inputs are
locked so that you can easily determine which fault originally caused
the machine to switch off, even if the input has reverted back to its
normal status in the meantime.

Note
Input monitoring begins 7 seconds after the machine starts up in
order to give the motor a chance to build up oil pressure and charge
voltage.

 Decommissioning

To bypass the pressure gauge, which prevents the machine starting

up without water pressure, a special adapter (GEKA on
compressed−air connection, not supplied) is used to connect to
compressed air instead of water.

" Connect the adapter.

" Open the air supply.

" Run the machine for a maximum of 5 seconds.

å Water is forced out of the pump.

" Close the air supply.

" Disconnect the adapter.

" Open the bypass line to the GEKA connector and empty the
high−pr essure pump.

This method is used in the factory.

Preservation If the high−pressure cleaner is to be put out of service or into

storage, it has to be preserved beforehand, if required.

Note
Preservation of the high−pressure cleaner prevents corrosion and
premature ageing. It is necessary if the machine:
– is not used for longer periods;
– is exposed to corrosive atmospheres during storage or
transportation.

" Preserve the machine with a suitable agent.

 Decommissioning

9.2 Storing the machine The high−pressure cleaner should only be stored in a dry, clean and
well ventilated area.

Danger
There is a risk of fuel vapours building up and igniting if the
high−pr essure cleaner is stored in a poorly ventilated area.

" Fill with all operating materials before putting into storage.

" If the high−pressure cleaner is to be stored for a long time you

must remove the battery and charge it regularly.

" The water in the hoses must be drained completely because

they could freeze and burst.

Caution
It is essential that frost protection measures be taken because frost
may damage the pump and water filter and cause the hoses to
burst.

9.3 Final decommissio- The final decommissioning and disposal requires complete
ning, disposal deinstallation of the power supply.
When disposing of all machine components, ensure that there is no
possibility of damage to health or the environment.

Environmental protection
Final disposal of the machine is carried out by a qualified specialist
company.

Disassemble the machine into its individual components for final

disposal.
