up.

Spray off loosened dirt with the high-
pressure ray.
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 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 maximum
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 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 water
cools down the cylinder head.
Restart the engine.
