Safety Devices

Safety devices serve for the protection of
the user and must not be put out of opera-
tion or bypassed with respect to their func-
tion.
Overflow valve
The overflow valve prevents the permissi-
ble working pressure from being exceeded.
Pressure switch
– If the pulling lever on the trigger gun is
released the pressure switch turns off
the pump, the high-pressure jet is
stopped. If the pulling lever is pulled the
pump is turned on again.
– The overflow valve and pressure switch
are set and sealed at the factory. Set-
ting only by customer service.
Motor protection switch
The motor protection switch switches off
the device if the power consumption is high.
