When unpacking check the contents. In-
form your dealer of any damage in trans-
portation.
Connection requirements
Electrical connection
The voltage shown on the rating plate must
match the supply voltage. The current source
must be properly earthed.
Only use splash-protected extension ca-
ble with a sufficient conductor cross-sec-
tion (10 m: 3 x 1.5 mm², 30 m: 3 x 2.5 mm²)
and unwind completely from the cable drum.
Connection to water line
Comply with the stipulations of the water
supply company.
Only use supply hoses (not supplied) with
the following dimensions: length at least 7.5
m, diameter at least ½”.
See rating plate or Technical Data for con-
nected values.
Operation
!
Serious danger!
Vehicle tyres and tyre valves can be da-
maged by the high-pressure jet and beco-
me perforated. The first sign of this is a dis-
coloration of the tyre. When cleaning them
maintain a distance of at least 30 cm.
Never grasp the power plug with wet hands.
Before each use check the power cord and
power plug for damage. Have a damaged
power cord replaced immediately by an
authorized Kärcher service point or an elec-
trical specialist.
Before each use check the high-pressure
hose for damage. Replace a damaged high-
pressure hose immediately.
!
Danger of injury!
Owing to the water jet emerging from the
high-pressure nozzle a recoil force opera-
tes on the handgun. Ensure you have a
secure footing and hold the handgun and
spray lance firmly.
If necessary wear protective clothing for
protection against return spray.
Water supply
Caution! Impurities in the intake water
damage the pump. To prevent this we ex-
pressly urge you to use the Kärcher water
filter (not included, order no. 4.730-097).
The operation of the high-pressure clea-
ner with a closed water supply line causes
damage to the pump. Please never ope-
rate the high-pressure cleaner with a clo-
sed water supply tap.
The unit can either be supplied from the
water main or from water in an open con-
tainer.
Water supply from the water main
• Connect a supply hose (not included) to
the water inlet of the unit and to the water
supply (e.g. water tap).
• Open the water supply.
Water supply from an open container
• Unscrew the coupling part for the water
inlet.
• Screw the suction hose with filter (not inclu-
ded, order-no. 4.440-238) onto the water
connection of the unit.
• Hang the filter in the container.
• Vent the unit before operation.
– Unscrew the high-pressure line at the
high-pressure outlet of the unit.
– Switch on the unit and let it run until water
free of bubbles emerges at the high-
pressure outlet.
– Switch off the unit and screw on the high-
pressure hose again.
Preparation
• Insert power plug.
• Turn master switch to “I”.
Switching on
• Press safety ratchet on the handgun and
pull the lever.
