ronment use detergent economically.

tions provided with these detergents.

Recommended cleaning method
– 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.
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 released, 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 tempertaure (80 °C),
the therm-valve on the pump opens and
lets out the hot water into the open.
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.
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.
Turn off the appliance
DANGER
Danger of scalding by hot water. After oper-
ation with hot water, the device must be op-
erated with open end handgun with cold
water for at least two minutes.
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.
