Drawing in water from open reservoirs
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 specifica-
tions for max. suction height).
 Fill the KÄRCHER suction hose with
backflow valve with water, screw to wa-
ter supply and hang into the water butt.
 Remove air from appliance before oper-
ation.
Switch on the appliance without con-
nection the high-pressure hose (max. 2
minutes) and run it until the water dis-
charging 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 appliance does not build up
pressure within two minutes, switch it off
and proceed as instructed in the Chapter
"Troubleshooting".
Illustration
 Insert the high pressure hose tightly into
the quick coupling on the appliance, it
will lock in audibly.
Note: Make sure the connection nipple
is aligned correctly.
 Check the secure connection by pulling
on the high pressure hose.
