Interrupting operation

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

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.
