flow control, the relief valve opens and part of the
water runs back to the suction side of the pump.
If the lever (2) is released, the pressure switch
switches the pump off. If the lever is retracted,
the pressure switch switches the pump on again.

The motor only starts up when the lever (2) is
retracted.
• Press safety switch (3) and retract lever (2).
• Set unit switch (17) to “I”.
• Adjust operating pressure and flow rate (+/–)
by rotating the pressure/flow control (13)
(infinitely variable).
• Set detergent metering valve (8) to the centre
position. Adjust dosage with + or – as required.
Recommended cleaning methods
1. Spray detergent sparingly over the dry surface
to be cleaned and let it take effect but not dry
out.
2. Spray off (rinse off) the loosened dirt using the
high-pressure spray.
Read off operating pressure on pressure gauge.
• When you have finished the operation, set
detergent metering valve (8) to “0” and switch
the cleaner on for about 1 minute and rinse it
clear of detergent.

Switching the cleaner off
• Set unit switch (17) to “0” and pull out power
plug.
High-pressure fan jet for dirt
accumulation over a large surface
• Close water inlet.
• Retract lever (2) until the cleaner is without

Kärcher. Proportions of detergent to be used
and accompanying instructions should be
noted carefully. Use detergents sparingly out
of consideration for the environment.

by the handle.
• Empty the detergent reservoir (10) before
transporting it horizontally.
Storing the cleaner
• Place the handgun (1) in the support (6).
• Reel in the high-pressure hose (5) and hang it
over the hose rest (18).
• Coil the connecting cable round the cable/hose
rest (20).

4. Operating the cleaner
Protection from sub-zero temperatures
Caution! Water which has frozen in the cleaner
can destroy parts of it. At best store the cleaner
in a heated room during the winter or empty it or
rinse it thoroughly with antifreeze.
• Empty the cleaner
– Unscrew supply hose and high-pressure hose
from the cleaner.
– Leave the cleaner running until the pump and
lines have emptied (max. 1 minute).
• Putting in antifreeze
For longer intervals between operations,
pumping antifreeze through the cleaner is to be
recommended. By this means also you obtain
a sure protection against corrosion.
5. Care and maintenance
Everyweek
Danger! Before undertaking any care or
maintenance work on the cleaner, pull out the
power plug.
Caution! When changing the oil, dispose of any
waste oil only at authorised collection points.
• Check oil level in oil reservoir (16): if the oil is
milky (water in oil), seek the help of Customer
Service immediately.
• Clean the strainer at the water outlet.
• Clean the filter at the suction hose for detergent.
Safetyinspection/maintenancecontract
You can arrange with your dealer to have
a regular safety inspection carried out or to have
a maintenance contract. Please seek advice on
this.
Annually or after 500 operating hours
• Change the oil
– For oil quantity and type see Technical
Specifications.
– Undo fastening screws (12), remove unit
cover, remove cover of oil reservoir.
– Lay cleaner on its side and drain oil into
a suitable container.
– Fill slowly with fresh oil; air bubbles have
to escape.
Each time before operating the cleaner
• Check connecting cable for damage (risk of
getting an electric shock), have a damaged
connecting cable replaced without delay by
authorised Customer Service personnel or an
electrician.
• Check high-pressure hose for damage
(danger of explosion), replace a damaged high-
pressure hose without delay.
• Check cleaner (pump) for any leaks. Three
drops per minute are allowable and can appear
on the underside of the cleaner. Seek the help
of Customer Service if leaks are more serious.
