1 Important safety instructions
Symbols used to mark instructions
For your own safety
The high-pressure washer
may only be used by persons
instruc ed in its use and who
have been expressly authorised
to do so.
Before using the
high-pressure
washer, be sure
to also read the
enclosed operat-
ing instructions
and keep them within reach at
all times.
Safety instructions
in these operating
instructions which
must be observed
to prevent risks to persons are
marked with this danger symbol.
Before starting the washer
If your 3-phase washer was
supplied without a plug, have
it fitted with a suitable 3-phase
plug with earth conductor, by an
electrician.
Before use, check that the highpressure washer is safe and in
proper condition.
This symbol is
used to mark
safety instructions that must
be observed to
prevent damage
to the machine and its performance.
This indicates tips
and in structions
to simplify work and to ensure
safe operation.
We strongly recommend that
the power supply to the high
pressure washer be connected
via a residual current circuit
breaker.
This device stops the supply
of electricity if the leakage current to earth exceeds 30 mA for
30 ms or it has an earth tester
circuit.
Although extremely easy to
operate, children should not be
allowed to use the washer.
General
Use of the high-pressure washer is subject to the applicable
local regulations.
Besides the operating instructions and the binding accident
prevention regulations valid
in the country of use, observe
recognised regulations for safety and proper use.
Do not use any unsafe work
techniques.

Regularly check whether the
electric cable is damaged or
shows signs of ageing.
Use the high-pressure washer
only when the electric cable is
in a safe condition. (risk of electric shock if damaged!).
Check the rated voltage of the
high-pressure washer before
connecting it to the mains
power supply. Ensure that the
voltage shown on the rating
plate corresponds to the voltage of the local mains power
supply.
Please observe the regulations and provisions applicable
in your country. Before putting
the high-pressure washer into
service, carry out a visual check
of all the major components.
CAUTION!
High-pressure water jets can
be dangerous if misused. The
jet must not be directed at
persons, animals, live electrical equipment or the washer
itself.
Wear appropriate protective
clothing and eye protectors.
Do not direct the jet towards
yourself or towards other persons in order to clean clothes
or footwear.
During operation of the washer,
recoil forces are produced at
the spraying device and, when
the spray lance is held at an
angle, a torque is also created.
The spraying device must
therefore be held firmly in both
hands.
Do not use the washer when
other people without protective
clothing are in the working area.
Check that cleaning will not
result in dangerous substances
(e.g. asbestos, oil) being
washed off the object to be
cleaned and harming the environment.
Do not clean delicate parts
made of rubber, fabric, etc. with
the 0° jet. Keep some distance
between high pressure nozzle
and surface in order to prevent
the surface from damage.
Operation
CAUTION!
Unsuitable extension cords
can represent a source of
danger. Always unwind cord
from the reels completely
to prevent the electric cable
overheating.
When using an extension cord,
connectors must be of watertight construction.
When using an extension cord,
check the minimum cross-sections of the cable:
Cable length
m
up to 20 m
20 to 50 m
Cross section
<16 A <25 A
ø1.5mm² ø2.5mm²
ø2.5mm² ø4.0mm²
Do not damage the electric cable (e.g. by driving over it, pulling or crushing it).
Disconnect the electric cable by
pulling the plug only (do not pull
or tug the electric cable).
Maintenance and repair
CAUTION!
Always disconnect the machine from the mains plug
socket before cleaning or carrying out maintenance work
on the washer.
Carry out only the maintenance
operations described in the
operating instructions. Use only
original spare parts.
Do not make any technical
modifications to the high-pressure washer.
Ensure that the machine is
regularly serviced by Authorised dealers in accordance
with the maintenace plan.
Failure to do so will invalidate
the warranty.
CAUTION!
High-pressure hoses, fittings
and couplings are important
for the safety of the washer.
Use only high-pressure parts
approved by the manufacturer!
Do not use the high-pressure
hose for lifting loads.
NOTE!
The specifications of the highpressure hose (max. permissible pressure and temperature)
are printed on the hose.
Do not continue to use the
washer if the electric cable
or high-pressure hose is
damaged.
Ensure adequate air circulation.
Do not cover the washer or operate it in inadequately ventilated rooms!
Store the washer where it will
not be exposed to frost!
Never operate the washer
without water. Even brief shortages of water result in severe
damage to the pump seals.
Electrical equipment
CAUTION!
Never spray electrical equipment with water: danger
for persons, risk of shortcircuiting.
The washer may only be connected to a correctly installed
plug socket.
Switching on the washer may
cause voltage fluctuations.
Voltage fluctuations should not
occur if the impedance at the
transfer point is less than 0.15
Ω. If in doubt ask your local
electricity supplier.
If the electric cable is damaged,
it must be replaced by authorized Service or an electrician
to avoid danger before use of
the cleaner is continued.
Use only the type of electric
cable specified in the operating
manual.
Please contact the Service department or an authorised specialist work-shop for all other
maintenance or repair work!
Testing
The washer conforms to the
German „Guidelines for Liquid Spray Jet Devices“. The
high-pressure washer must be
subjected to a safety examination in accordance with the „Accident Prevention Regulations
for Working with Liquid Spray
Jet Devices“ as required, but at
least every 12 months, by an
authorised inspector.
