when the water jet is discharged. Make
sure that you have a firm footing. Hold the
handgun and spray lance firmly.
Power nozzle
The appliance is equipped with the follow-
ing nozzles:
 Power nozzle, 15° spray angle
High pressure flat spray (15°) for large
–
dirt areas
Note
To prevent damage due to too much pres-
sure, always position high pressure ray first
from a greater distance towards object to
be cleaned.
Set working pressure and flow rate
 Pull the lever on the handgun.
 Set the working pressure and quantity
by turning the pressure/ quantity regula-
tion mechanism at the pump unit.
The working pressure can be read from
the manometer.

Interrupting operation

 Release the lever on the trigger gun.
 Use the safety catch to secure the
handgun lever.
 Store the hand spray gun and spray
pipe in the accessory mount.
 In case of extended interruptions (sev-
eral minutes), switch off the engine.
Note
When the lever of the hand spray gun is re-
leased, the engine continues to run at de-
creased 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.

water (sea water), open the hand spray
gun and rinse the appliance for at least
2 - 3 minutes using tap water.

to OFF and close the fuel supply valve.
