Warning
According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply
without a system separator. Use a
suitable system separator manufactured by
KÄRCHER; or, as an alternative, a system
separator as per EN 12729 Type BA. Water
flowing through a system separator is consid-
ered non-drinkable.
Note:
Impurities in the water can damage the
high-pressure pump and accessories. For
protection, the use of the KÄRCHER water fil-
ter (optional accessory, order no. 4.730-059)
is recommended.
Observe regulations of water supplier.
For connection values, see type plate/techni-
cal data.
Use a fibre-reinforced water hose (not in-
cluded) with a standard coupling. (Mini-
mum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
Illustration
Screw the coupling element (supplied) to
the water connection on the appliance.
Push the water supply hose onto the cou-
pling unit, then connect it to the water sup-
ply.
This high-pressure cleaner is suited to work
with the KÄRCHER suction hose with back-
flow valve (Optional accessory, order no.
4.440-238) to draw in surface water, e.g. from
water butts or ponds (see specifications for
max. suction height).
Fill the KÄRCHER suction hose with
backflow valve with water, screw to water
supply and hang into the water butt.
Appliance ventilation: Switch the appli-
ance on with the high-pressure hose de-
tached and operate (max. 2 minutes) until
the water exits the high-pressure connec-
tion without bubbles. Switch off appliance
and reconnect high-pressure hose.
Caution
Dry runs lasting longer than two minutes lead
to damages to the high pressure pump. If the
appliance does not build up pressure within
two minutes, switch it off and proceed as in-
structed in the Chapter "Troubleshooting".
Illustration
Push the spray lance into the trigger gun
and fasten it by turning it through 90°.
Illustration
Unwind the high pressure hose from the
hose drum. Hold on to the transport han-
dle during this procedure.
Note
: If the hand crank is in its secured
position, fold it up first.
Completely open the water tap.
Insert the mains plug into the socket.
