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
– If the hand spray gun is closed, the
overflow valve opens and the high pres-
sure pump diverts the water back to the
14
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.
DANGER
Risk of injury! Device, tubes, high pressure
hose and connections must be in faultless
condition. If they are not in a perfect state
then the appliance must not be used.
