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 with pressure switch
While reducing the water supply/quantity
regulation at the pump head, the overflow
valve opens and part of the water flows
back to the pump suck side.
If the lever on the trigger gun is released
the pressure switch turns off the pump, the
high pressure jet is stopped. If the lever is
pulled the pump is turned on again.
The safety valve opens when the permissi-
ble operating pressure is exceeded; water
flows back to the suction side of the pump.
The overflow valve, pressure switch and
safety valve are set and sealed at the fac-
tory.
Setting only by customer service.
