yourself or towards other per-
sons 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 envi-
ronment.
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.
Do not use the high-pressure
hose for lifting loads.
NOTE!
The specifications of the high-
pressure hose (max. permissi-
ble 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 op-
erate it in inadequately ventila-
ted rooms!
Store the washer where it will
not be exposed to frost!
Never operate the washer
without water. Even brief short-
ages of water result in severe
damage to the pump seals.
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 water-
tight construction.
When using an extension cord,
check the minimum cross-sec-
tions of the cable:
Cable length Cross section
m
<16 A
up to 20 m ø1.5mm² ø2.5mm²
20 to 50 m ø2.5mm² ø4.0mm²
Do not damage the electric ca-
ble (e.g. by driving over it, pull-
ing or crushing it).
Disconnect the electric cable by
pulling the plug only (do not pull
or tug the electric cable).
Electrical equipment
CAUTION!
Never spray electrical equip-
ment with water: danger
for persons, risk of short-
circuiting.
The washer may only be con-
nected 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.
Maintenance and repair
CAUTION!
Always disconnect the ma-
chine from the mains plug
socket before cleaning or car-
rying 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-pres-
sure washer.
Ensure that the machine is
regularly serviced by Autho-
<25 A
rised 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 manufac-
turer!
If the electric cable is damaged,
it must be replaced by autho-
rized 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 de-
partment or an authorised spe-
cialist work-shop for all other
maintenance or repair work!
Testing
The washer conforms to the
German „Guidelines for Li-
quid Spray Jet Devices". The
high-pressure washer must be
subjected to a safety examina-
tion in accordance with the „Ac-
cident Prevention Regulations
for Working with Liquid Spray
Jet Devices" as required, but at
least every 12 months, by an
authorised inspector.
