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 con-
sidered non-drinkable.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!
Note: Impurities in the water can damage
the high-pressure pump and accessories.
For protection, the use of the KÄRCHER
water filter (optional accessory, order no.
4.730-059) is recommended.
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).
 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.
 Separate the high pressure hose from
the high pressure connection of the ap-
pliance.
 Appliance ventilation.
Let the appliance run when the high-
pressure hose is not connected and run
it until the water which discharges from
the high-pressure outlet is free of bub-
bles. Switch off appliance and recon-
nect 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".
Caution
The appliance is delivered without engine
oil. Please fill in engine oil before using the
appliance for the first time.
 Fill up the fuel tank and check the oil
level.
See Operating Instructions of motor.
 Connect the high pressure hose to the
high pressure connection of the appli-
ance.
 Push the spray lance into the trigger
gun and fasten it by turning it through
90°.
 Completely open the water tap.
 Start the motor.
