 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.
 This appliance was designed to be
used with detergents which are sup-
plied or recommended by the manufac-
turer. The use of other detergents or
chemicals may compromise the safety
of the appliance.
Caution
 In case of extended downtimes, switch
the appliance off at the main switch / ap-
pliance switch or remove the mains
plug.
 Do not operate the appliance at temper-
atures below 0 °C.
 Observe a distance of at least 30 cm
when using the jet to clean painted sur-
faces to avoid damaging paintwork.
 Never leave the appliance unattended
when it is in operation.
 Make sure that the power cable or ex-
tension cables are not damaged by run-
ning over, pinching, dragging or similar.
Protect the power cable from heat, oil,
and sharp edges.

All current-conducting parts in the work-
ing area must be protected against jet
water.
 The appliance may only be connected
to an electrical supply which has been
installed in accordance with IEC 60364.
 The appliance may only be connected
to alternating current. The voltage must
correspond with the type plate on the
appliance.
 For safety reasons, we recommend that
you operate the appliance only via an
earth-leakage circuit breaker (max.
30 mA).
 Cleaning operations which produce oily
waste water, e.g. engine washes, un-
derbody washes, may only be carried
out using washing stations equipped
with an oil separator.
The high pressure hose is specially con-
structed with reinforced walls to handle wa-
ter pressure up to 14,5 MPa (2100 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.
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 is stopped. If the lever is
pulled the pump is turned on again.
Caution
Create stability for the appliance prior to all
work on or with the appliance to prevent ac-
cidents or damage.
–
The stability of the appliance is warrant-
ed when it is placed onto an even sur-
face.
