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 maxi-
mum 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 be-
low 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 wa-
ter cools down the cylinder head.
 Restart the engine.
Turn off the appliance
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.
 Set the appliance switch at the engine
to OFF and close the fuel supply valve.
 Shut off water supply.
 Activate hand spray gun until device is
pressure-less.
 Secure the hand spray gun using the
safety catch so that it doesn't open ac-
cidentally.
 Remove the water inlet hose from the
appliance.
