Observe regulations of water supplier.
For connection values, see type plate/
technical data.
Use a fibre-reinforced water hose
(not included) with a standard cou-
pling. (Minimum diameter 1/2 inch
(13 mm), minimum length 7.5 m).
Push the water supply hose onto
the coupling unit, then connect it to
the water supply.
This high-pressure cleaner is suited to
work with the KÄRCHER suction hose
with backflow valve (Optional accesso-
ry, order no. 4.440-238) to draw in sur-
face water, e.g. from water butts or
ponds (see specifications for max. suc-
tion height).
Fill the KÄRCHER suction hose
with backflow valve with water,
screw to water supply and hang into
the water butt.
Remove air from appliance before
operation.
Switch on the appliance without
connection the high-pressure hose
(max. 2 minutes) and run it until the
water discharging from the high-
pressure outlet is free of 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 appli-
ance does not build up pressure
within two minutes, switch it off
and proceed as instructed in the
Chapter "Troubleshooting".
Illustration
