Operation with detergent
WARNING
Unsuitable detergents can cause damage

with these detergents. For considerate
treatment of the environment use detergent
economically.
Follow the safety instructions for using de-
tergents.
– Use only those detergents approved by
the manufacturer of the appliance.
– Kärcher detergents ensure smooth
functioning. Please consult us or ask for
our catalogue or our detergent informa-
tion sheets.

After operation with detergent
 Set dosing value for detergent to "0".
 Open the hand spray gun and rinse the
appliance for at least 1 minute.

Interrupting operation

 Release the lever on the trigger gun.
Note:
When the lever of the trigger gun is re-
leased, the motor continues to run at idling
speed. The water thus circulates within the
pump and heats up. When the cylinder
head at the pump has reached the maxi-
mum permissible temperature (80 °C), the
safety thermostat at the cylinder head
switches off the motor. The device can be
restarted after cooling down to below 50 °C.
Cooling can be hastened while using com-
pressed water from the water supply pipes:
 Pull the lever of the hand spray gun for
2 - 3 minutes so that the circulating wa-
ter cools down the cylinder head.
 Restart the engine.
Turn off the appliance
After operating the water using saline water
(sea water), open the hand spray gun and
rinse the appliance for at least 2 - 3 minutes
using tap water.
 Set the appliance switch at the engine
to OFF and close the fuel supply valve.
 Shut off water supply.
 Activate trigger gun until device is pres-
sure-less.
 Secure the hand spray gun using the
safety catch so that it doesn't open ac-
cidentally.
 Remove the water inlet hose from the
appliance.
CAUTION
Risk of injury and damage! Observe the
weight of the appliance when you transport it.
 Lift appliance by the pipe frrame and
carry it.
 When transporting in vehicles, secure
the appliance according to the guide-
lines from slipping and tipping over.
