sonous. Do not use acetone, undiluted
acids and solvents as they are aggres-
sive towards the materials from which
the appliance is made.
Safety instructions
ƽ Danger
„ Never touch the mains plug and the
socket with wet hands.
„ The appliance must not be used if the
power cord or important parts of the ap-
pliance, e.g. high-pressure hoses, trig-
ger gun or safety devices are damaged.
„ Check the power cord with mains plug
for damage before every use. If the
power cord is damaged, please arrange
immediately for the exchange by an au-
thorized customer service or a skilled
electrician.
„ Check the high-pressure hose for dam-
age before every use. Please arrange
for the immediate exchange of a dam-
aged high-pressure hose.
„ The appliance may not be used in areas
where a risk of explosion is present.
„ If the appliance is used in hazardous ar-
eas (e.g. filling stations) the corre-
sponding safety provisions must be
observed.
ṇ Warning
„ The mains plug and the coupling of an
extension cable must be watertight and
must never lay in the water.
„ Unsuitable extension cables can be
hazardous. Only use extension cables
outdoors which have been approved for
this purpose and labelled with a suffi-
cient cable cross-section:
1 - 10 m: 1.5 mm2; 10 - 30 m: 2.5 mm2
„ Always fully unroll electrical cables from
the cable drum.
„ High-pressure hoses, fixtures and cou-
plings are important for the safety of the
appliance. Only use high-pressure hos-
es, fixtures and couplings recommend-
ed by the manufacturer.
„ This device is not intended for use by
persons (including children) with re-
duced physical, sensory or mental abil-
ities or lacking experience and/or
knowledge, unless they are supervised
by a person responsible for their safety
or are instructed by these persons on
the use of the device. Children should
be supervised, to ensure that they do
not play with the device.
„ The operator must use the appliance
correctly. When working with the appli-
ance, he must consider the local condi-
tions and pay due care and attention to
other persons, in particular children,
who are nearby.
„ Do not use the appliance when there
are other persons around unless they
are also wearing safety equipment.
„ Wear protective clothing and safety
goggles to protect against splash back
containing water or dirt.
„ High-pressure jets can be
dangerous if improperly
used. The jet must not be
directed at persons, ani-
mals, live electrical equipment or at the
appliance itself.
„ The high-pressure jet must not be di-
rected at other persons or directed by
the user at him/herself to clean clothing
or footwear.
„ Never use the appliance to clean ob-
jects containing hazardous substances
(e.g. asbestos).
„ Vehicle tyres or tyre valves are suscep-
tible to damage from the high-pressure
jet and may burst. The first indication of
this is a discolouration of the tyre. Dam-
aged vehicle tyres/tyre valves are high-
ly dangerous. Ensure that a distance of
at least 30 cm is observed when clean-
ing with the jet!
„ Never draw in fluids containing solvents
or undiluted acids and solvents! This in-
cludes petrol, paint thinner and heating

the subject.
Î Fill the detergent solution in the deter-
gent tank (observe dosage instructions
on the packaging of the detergent).
Î Adjust the suction volume of the deter-
gent solution by means of the dosage
regulator for detergents.
Caution
Use the high pressure cleaner only when
you have mounted the water filter.
Never operate the high-pressure cleaner
when the tap is turned off as dry running will
damage the high-pressure pump.
Î Unwind the high pressure hose from the
hose drum.
