up. When the cylinder head at the pump
has reached the maximum permissible
temperature (80 °C), the safety thermostat
at the cylinder head switches off the motor.

down to below 50 °C.
Cooling can be hastened while using com-
pressed water from the water supply pipes:

minutes so that the circulating water
cools down the cylinder head.
