Recommended cleaning method
1. Spray the detergent sparingly on the dry surface and
let it work for a while (do not let it dry).
2. Rinse off the loosened dirt with the high-pressure
jet.
Rinsing the cup foam lance
The foam lance must be rinsed after use to prevent the
development of detergent deposits.
1. Unscrew the container.
2. Pour the remaining detergent back into the original
packaging.
3. Fill the container with clear water.
4. Screw the container onto the foam nozzle.
5. Operate the foam nozzle for approx. 1 minute to
flush the detergent residue.
6. Empty the container.
Interrupting operation
1. Close the high-pressure gun.
2. Push the safety latch forwards.
The high-pressure gun is secured.
Note
If the high-pressure gun is closed, the motor continues
to run at idle speed. The water then circulates within the
pump and heats up. When the cylinder head at the
pump has reached the maximum permissible tempera-
ture (80 °C), the thermostat valve on the pump opens
and lets out the hot water into the open. Cooling can be
accelerated when operating with pressurized water
from the water pipe network:
3. Open the high-pressure gun for about 2-3 minutes.
The water flowing through it cools the cylinder head.
DANGER
Hot water
Risk of scalding
After operation with hot water, operate the device for at
least 2 minutes with cold water with the high-pressure
gun open for cooling down.
