DANGER
– Do not use high pressure cleaners
when there has been an oil spill; move
the appliance to another spot and avoid
any sort of spark formation.

Safety Devices

Safety devices serve for the protection of the
user and must not be put out of operation or
bypassed with respect to their function.
Overflow valve
– If the hand spray gun is closed, the
overflow valve opens and the high pres-
sure pump diverts the water back to the
pump suction side. Thus the permissi-
ble working pressure is not exceeded.
– The overflow valve is set by the manu-
facturer and sealed. Setting only by
customer service.
Safety valve
The safety valve opens when the permissi-
ble operating pressure is exceeded (see
Technical Data); water flows outside.
The safety valve is set by the manufacturer
and sealed. Setting only by customer service.
Thermostat valve
The thermostat valve protects the high-
pressure pump from unacceptable heating
during circuit operation when the trigger
gun is closed.
The thermostat valve opens when the permis-
sible water temperature of 80°C is exceeded
and lets out the hot water into the open.

Start up

DANGER
