Operation

!
Serious danger!
Vehicle tyres and tyre valves can be damaged
by the high-pressure jet and become
perforated. The first sign of this is a
discoloration 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
electrical 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 operates
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
expressly urge you to use the Kärcher water
filter (not included, order no. 4.730-097).
The operation of the high-pressure cleaner
with a closed water supply line causes
damage to the pump. Please never operate
the high-pressure cleaner with a closed
water supply tap.
The unit can either be supplied from the
water main or from water in an open container.
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
included, 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".
