For your safety
Before you use the cleaner for the first time,
read these operating instructions and take
special note of the accompanying booklet
"Safety Instructions for High-Pressure Clean-
ers" No. 5.951-949.
Use of the cleaner
Use this unit exclusively for
– cleaning with high-pressure jet and deter-
gent (e.g. cleaning of machines, vehicles,
buildings, tools),
– cleaning with high-pressure jet without de-
tergent (e.g. cleaning facades, terraces,
gardening equipment).
For stubborn dirt we recommend the dirt
blaster as an optional accessory (for HD ...
Plus included in the delivery).
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.
