Starting
Do not simply discard the packing mate-
rials with the house-hold waste. Take the
packing materials to the appropriate collec-
tion areas for recycling.
Impurities in the intake water damage the
pump. To prevent this we expressly urge
you to use the Kärcher water filter (order
no. 4.730-059).
The operation of the high-pressure cleaner
with a closed water supply line causes da-
mage to the cylinder head unit. Please ne-
ver operate the high-pressure cleaner with
a closed water supply tap.
If you are using an extension cable, it should
always be completely unwound from the
cable drum and have a sufficient cross-
sectional area:
Operation with high pressure
The appliance is equipped with a pressure-
operated switch. The motor starts only if the
lever of the gun is pulled.
The safety ratchet does not lock the lever of
the gun during operation but only prevents
it from opening unintentionally.
Operation with Detergent
We recommend that you use detergent
sparingly for the sake of the environment.
Observe the recommended dosage on the
detergent label.
By offering you an individualised range of
clea-ning and preserving agents, Kärcher
guarantees trouble-free operation of the
unit.
We recommend the following cleaning
methods:
Step 1: Loosening dirt
Spray on detergent sparingly and allow to
react for a short time.
Step 2: Removing dirt
Spray off the loosened dirt with the high-
pressure spray.

Switching Off
The appliance should be rinsed clean after
detergent has been used. To do this, sus-
pend the detergent suction hose in a con-
tainer of clean water, and run the pump for
approx. 1 minute.
Pull the trigger until there is no more pres-
sure in the appliance, and secure the trigger
with the safety ratchet against unintentional
opening.
Frost will destroy an appliance which has
not been completely emptied of water. Ide-
ally, the appliance should be stored in a
frost-free room.
Troubleshooting
!Note: Disconnect the appliance from the
power mains before all repair work.
Appliance does not Work
-Check whether the voltage shown on the
rating plate corresponds to that of the po-
wer source.
-Check the connector cable for damage.
Appliance does not reach Operational
Pressure
-Vent the appliance:Allow the pump to ope-
rate without the high-pressure hose until
water appears at the high-pressure outlet
without any more bubbles.Then reattach
the high-pressure hose.
-Clean the strainer in the water connection.
-Check the inlet water flow rate.
-Check all inlet pipes to the pump for leaks
or block-age.
Strong Pressure Fluctuations
-Clean the high-pressure nozzle. Remove
dirt from the nozzle hole with a needle and
then rinse out with water from the front.
Pump Leaks
-10 drops per minute are permissible. In the
case of more serious leakage, you should
contact the authorized customer service.
No Detergent Suction
-Clean the detergent suction hose with fil-
ter, and check for leaks.

General Information
Purpose
Use the appliance to clean machines, vehic-
les, buildings, tools etc.
Clean facades, terrasses, garden equip-
ment etc. without detergent only with the
high-pressure spray.
Cleaning with the use of a high-pressure
cleaner brings an 85% reduction in the con-
sumption of fresh water.
Cleaning tasks which produce waste wa-
ter mixed with oil – e.g. when washing en-
gines or the undersides of vehicles – should
only be carried out at a specific washing
point that is equipped with an oil separator.
Safety Equipment
When the spary gun is closed, the overflow
valve switches off the appliance via a pres-
sure-operated switch. The overflow valve is
also a safety device against exceeding the
maximum allowable working pressure.
Disposal of old equipment
In the development of this appliance careful
attention has been given to its ability to be
easily recycled. Nevertheless, it contains
parts or substances which should not go
into the household rubbish. You can obtain
information from any Kärcher sales house
about disposal facilities which protect the
environment.
!Note: The tilt switch contains mercury.
Do not place the switch in regular trash. the
switch must be disposed of proberly or re-
cycled.
