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
oil. The spray mist thus generated is
highly inflammable, explosive and poi-
sonous. Do not use acetone, undiluted
acids and solvents as they are damag-
ing to the materials from which the ap-
pliance is made.
몇Warning
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

Caution
Safety devices protect the user and must
not be modified or bypassed.
The appliance switch prevents unintention-
al operation of the appliance.
This lock locks the lever of the trigger gun
and prevents the inadvertent start of the ap-
pliance.
The overflow valve prevents the permissi-
ble working pressure from being exceeded.
If the lever on the trigger gun is released
the pressure switch turns off the pump, the
high-pressure jet ist stopped. If the lever is
pulled the pump is turned on again.
The high pressure hose is specially con-
structed with reinforced walls to handle wa-
ter pressure up to 13 MPa (1900 psi) - it can
be easily damaged and should be stored
carefully.
Do not kink.
Do not drive vehicles over the hose.
Do not expose the hose to sharp edges
or corners.
Misuse will lead to ballooning or premature
failure and will invalidate warranty.
The scope of delivery of your appliance is il-
lustrated on the packaging. Check the con-
