Transportation; Storage; Care And Maintenance - Kärcher HDS 8/20 De Bedienungsanleitung

Note
When the trigger gun is closed, the engine continues to
run at no load speed. The water thus circulates within
the pump and gets heated. When the cylinder head at
the pump has reached the maximum permissible tem-
perature (80°C), the safety thermostat at the cylinder
head will switches off the engine. The device can be re-
started after cooling down to below 50°C.
3. Cooling can be hastened while using compressed
water from the water supply pipes: Pull the lever of
the trigger gun for 2 - 3 minutes so that the circulat-
ing water cools down the cylinder head.
After each operation
DANGER
Danger of scalding by hot water. After cleaning with hot
water, release the gun and rinse the appliance with cold
water for at least 2 minutes.
Turning off the appliance
WARNING
Never stop the engine at full load when the trigger gun
is opened.
Note
After operating the water using saline water (e.g. sea
water), open the trigger gun and rinse the appliance for
at least 2 - 3 minutes using tap water.
1. Turn the temperature adjustment switch off and wait
until the discharge water is at normal temperature.
2. Release the lever on the trigger gun for 2 minutes.
3. Turn off the engine according to the requirements in
the engine operating instructions.
