ded) with a standard coupling: - Mini-
mum diameter, 1/2 inches (13 mm). -
Minimum length, 7.5 m.
Screw the coupling unit (supplied) to the
water connection on the appliance.
Push the water supply hose onto the
coupling unit, then connect it to the tap.
Caution
Never operate the high-pressure cleaner
when the tap is turned off as dry running will
damage the HP pump.
If the water supply is not clean, the Kärcher
water filter must be used (special accessory
- order No. 4.730-059).
Water supply from open reservoirs
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).
Use the Kärcher water filter to protect the
HP pump and accessories (special ac-
cessories). This filter removes dirt from
incoming water.
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.
Remove air from appliance before ope-
ration: Switch on the appliance when the
HP hose is not connected and run it until
the water which discharges from the HP
outlet is free of bubbles. Switch off ap-
pliance and connect HP hose.
