Safety features
Overflow valve with pressure
switch
On reducing the flow rate with the pressure
and flow control, the relief valve opens and
part of the water runs back to the suction side
of the pump.
If the lever of the hand-held spray gun is re-
leased, the pressure switch switches the
pump off. If the lever is retracted, the pressure
switch switches the pump on again.
Safety valve
The safety valve opens when the admissible
operating excess pressure is exceeded; the
water flows back to the pump suction side.
Overflow valve, pressure switch and safety
valve are present in the factory and are
sealed.
Adjustments are made only by Customer
Service.

tents of the packaging. If there has been
any damage in transit inform the dealer.
– Do not dispose of the packaging with the
household rubbish, hand it in at the appro-
priate collection point for recycling.

gun with pressure and flow control.
For appliances without hose reel:
Screw on high-pressure hose to the high-
pressure outlet.
For appliances with hose reel:
Insert the crank handle in the hose reel
shaft, until it snaps into position.
It is advisable to lay the high-pressure hose
out in a straight line before reeling it up.
Wind the high-pressure hose up in even
layers on the hose reel by turning the crank
handle.
Select the rotational direction so that the
high-pressure hose does not kink.
The packaging material can be re-
cycled. Please do not place the pak-
kaging into the ordinary refuse for
disposal, but arrange for the proper
recycling.
Old appliances contain valuable ma-
terials that can be recycled. Please
arrange for the proper recycling of
old appliances. Batteries, oil, and si-
milar substances must not enter the
environment. Please dispose of your
old appliances using appropriate col-
lection systems.
