Î Use the Kärcher water filter to protect
the HP pump and accessories (special
accessories, order no. 4.730-059). This
filter removes 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, order no. 4.440-238) and
suspended inside the water butt.
Î Remove air from appliance before oper-
ation: 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.
Note: Fill suction hose with water before
use, this will help ventilate the pump of
air.
