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
Cleaners” No. 5.951-949.
Use of the cleaner
Use this cleaner exclusively for
– cleaning with high-pressure jet and
detergent (e.g. cleaning of machines,
vehicles, buildings, tools)
– cleaning with high-pressure jet without
detergent (e.g. cleaning facades,
terraces, gardening equipment).
For stubborn dirt we recommend the dirt
blaster as an optional accessory.
Safety features
Relief 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 is released, the pressure switch
switches the pump off. If the lever is
retracted, the pressure switch switches the
pump on again.
Safety valve (only in HD 690/
HD 690 SX)
The safety valve opens when the maximum
allowable operating pressure is exceeded:
the water flows back to the suction side of
the pump.
