Safety devices
Safety devices protect the user and may not be disabled
or functionally circumvented.
Overflow valve with 2 pressure switches
● When the water volume at the pump head is re-
duced, the overflow valve opens and some of the
water flows back to the pump suction side.
● If the high-pressure gun is closed so that all the wa-
ter flows back to the pump suction side, the pres-
sure switch on the overflow valve switches off the
pump.
● If the high-pressure gun is opened again, the pres-
sure switch on the cylinder head switches the pump
on again.
● The overflow valve is set and sealed at the factory.
The adjustment is performed only by customer ser-
vice.
● The safety valve opens if the overflow valve or pres-
sure switch is faulty.
● The safety valve is adjusted and sealed at the facto-
ry. The adjustment is performed only by customer
service.
