Initial start-up

When the appliance is delivered, the HP
hose and handgun are not attached, this
prevents buckling. Please mount these be-
fore using the appliance for the first time.
" Push out the safety clip in the handgun
using e.g. a small screwdriver.
" Join HP hose and handgun together.
" Push clip in until it engages and check
that it is securely fastened by pulling on
the HP hose.
" Remove cable tie and unroll HP hose

Water supply

Water supply from mains
For connection values, see type plate/tech-
nical data.
Observe regulations of water supplier.
" Use a fibre-reinforced hose (not includ-
ed) with a standard coupling: - Minimum
diameter, 1/2 inches (13 mm). - Mini-
mum 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).
Drawing in water 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, order no. 4.730-059). This fil-
ter 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, order no. 4.440-238) and
suspended inside the water butt.
" 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 appli-
ance and connect HP hose.
Note: If filling the suction hose with water
before, the air better removes from the
appliance.
