Caution
Never operate the high-pressure cleaner
when the tap is turned off as dry running will
damage the High pressure pump.
If the water supply is not clean, the Kärcher
water filter must be used (special accessory
- order No. 4.730-059).
When fitted with the appropriate accesso-
ries, this high-pressure cleaner can draw in
surface water, e.g. from water butts or
ponds (max. suction height 0.5 m).
Î
Use the Kärcher water filter to protect
the high pressure pump and accesso-
ries (special accessories). This filter re-
moves dirt from incoming water.
Î As the standard coupling system is not
suitable for use in suction mode, the
Kärcher suction hose with integrated fil-
ter should be used instead (special ac-
cessory) and suspended inside the
water butt.
Î Remove air from appliance before oper-
ation: Switch on the appliance when the
high pressure hose is not connected
and run it until the water which discharg-
es from the high pressure outlet is free
of bubbles. Switch off appliance and
connect high pressure hose.
Note : The appliance deaerates faster if
you first fill the suction hose with water.
Î Screw high pressure hose on to high
pressure outlet on appliance.
Î Push the appropriate spray lance on to
the handgun and fasten it by turning it
through 90°.
Î Open tap.
Î Plug in the main plug.
Î
Set main switch to “I/ON”.

Risk of injury
