Operating instructions

English 13
Use the high-pressure jet for cleaning machines, vehi-
cles, buildings, tools and similar objects.
We recommend using a rotary nozzle as a special ac-
cessory for stubborn soiling.
The HD...Plus is supplied with a rotary nozzle.
ATTENTION
Dirty water leads to premature wear or deposits in
the device.
Clean the device using only clean water, or recycled wa-
ter that does not exceed the following limits:
 pH value: 6.5...9.5
 Electrical conductivity: Conductivity of fresh water
+ 1200 µS/cm, maximum conductivity 2000 µS/cm
 Settleable particles (sample volume 1 l, settling time
30 minutes): < 0.5 mg/l
 Filterable particles: < 50 mg/l, no abrasive sub-
stances
 Hydrocarbons: < 20 mg/l
 Chloride: < 300 mg/l
 Sulphate: < 240 mg/l
 Calcium: < 200 mg/l
 Total hardness: < 28 °dH, < 50° TH, < 500 ppm (mg
CaCO
3
/l)
 Iron: < 0.5 mg/l
 Manganese: < 0.05 mg/l
 Copper: < 2 mg/l
 Active chloride: < 0.3 mg/l

Symbols on the device
The device may not be connected to the pub-
lic drinking water network.
The high-pressure jet must not be directed at
persons, animals, live electrical equipment or
at the device itself. Protect the device from
frost.
Safety devices
Safety devices protect the user and may not be disabled
or functionally circumvented.
The overflow valve, pressure switch an safety valve are
set and sealed by the manufacturer. Adjustments are
performed only by customer service.
Overflow valve with pressure switch
When the water quantity is reduced via the pressure/
quantity control on the trigger gun, the overflow valve
opens and part of the water flows back to the suction
side of the pump.
When the trigger on the high-pressure gun is release,
the pressure switch switches off the high-pressure
pump and the high-pressure jet stops.
The pump switches on again when the trigger is pulled.
Safety valve
The safety valve opens when the permissible operating
pressure is exceeded and the water flows back to the
suction side of the pump.
