Safety devices serve to protect the user
and must not be rendered inoperational or
their functions bypassed.
The switch prevents unintented starting of
the appliance. Stop the appliance during
breaks or after operation.
The safety catch on the trigger gun pre-
vents the appliance from being switched on
unintentionally.
–
While reducing the water supply/quanti-
ty regulation at the pump head, the
overflow valve opens and part of the
water flows back to the pump suck side.
–
If the hand spray gun is closed, the
overflow valve opens and the entire wa-
ter volume will flow back to the pump
suction side. The pressure switch on
the overflow valve sends a signal to the
control, which switches the pump off af-
ter approx. 30 seconds of trailing time.
–
If the hand spray gun is opened, the
pressure switch on the cylinder head
turns the pump back on.
The overflow valve and pressure switch are
set and sealed at the factory. Setting only
by customer service.
The safety valve opens when the overflow
valve is defective.
The safety valve is set by the manufacturer
and sealed. Setting only by customer serv-
ice.
The lack of water fuse shuts off the engine
when the water supply is scarce (water
pressure too low).
The indicator lamp "lack of water" will illumi-
nate.
The electrical circuit breaker breaks the
power circuit when there is no voltage in
one of the phases.
The winding proctection contact in the mo-
tor winding of the pump drive switches off
the engine when there is a thermal over-
load.
