몇 Warning

Unsuitable detergents can cause damage

to the appliance and to the object to be

cleaned. Use only those detergents that

have been approved by Kärcher. Observe

the dosage and other instructions provided

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.

 Suspend end of suction hose in a con-

tainer filled with detergent.

 Set nozzle to "CHEM".

 Set dosing value for detergent to the

desired concentration.

– Loosen the dirt:

Spray detergent economically and let it

work for 1...5 minutes but do not let it

dry up.

– Remove the dirt:

Spray off loosened dirt with the high

pressure jet.

 Set dosing value for detergent to "0".

 Open the hand spray gun and rinse the

appliance for at least 1 minute.

 Release the lever on the trigger gun.

Note

When the lever of the hand spray gun is re-

leased, the engine continues to run at zero

speed. The water thus circulates within the

pump and gets heated. 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 engine. The appliance can

be restarted after being cooled down to be-

low 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.
