Safety Devices

Safety devices serve to protect the user
and must not be rendered in operational or
their functions bypassed.
Power switch
The switch prevents unintented starting of
the appliance. Stop the appliance during
breaks or after operation.
Safety catch
The safety catch on the trigger gun pre-
vents the appliance from being switched on
unintentionally.
Overflow valve with pressure
– 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
(does not apply to HD 16/15-4).
– 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.
Electrical circuit breaker
The electrical circuit breaker breaks the
power circuit when there is no voltage in
one of the phases.

Winding protection contact
The winding protection contact in the motor
winding of the pump drive switches off the
engine when there is a thermal overload.
The safety valve opens when there is a
problem in the pressure switch. This valve
is set and sealed in the factory. Do not
change the setting.
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.
Check oil level
 Cut off tip of oil container cover (HD 25/
15-4).

oil level display.
 Add oil if required (see technical speci-
fications).
