Observe regulations of water supplier.
For connection values, see type plate/tech-
nical data.
Use a fibre-reinforced water hose (not
included) with a standard coupling.
(Minimum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
Illustration
Screw the supplied coupling element to
the water connection on the appliance.
Push the water supply hose onto the
coupling unit, then connect it to the wa-
ter supply.
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.
Appliance ventilation: Switch the appli-
ance on with the high-pressure hose
detached and operate (max. 2 minutes)
until the water exits the high-pressure
connection 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 instructed 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
handle 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.
Turn on the appliance “I/ON”.
ṇ Danger
The trigger gun is subjected to a recoil force
when the water jet is discharged. Make
sure that you have a firm footing and are
also holding the trigger gun and spray lance
firmly.
Caution
Prior to cleaning, make sure that the high
pressure is placed safely on level ground.
Wear protective goggles and protective
clothing during the cleaning process.
