High-pressure jets can be dan-
gerous if improperly used. The
jet may not be directed at persons, animals,
live electrical equipment or at the appliance
itself.
According to applicable regula-
tions, the appliance must never be
used on the drinking water net
without a system separator. A suit-
able system separator by KÄRCHER or al-
ternatively a system separator according to
EN 12729 type BA must be used.
Water that was flowing through a system
separator is considered non-drinkable.
몇
CAUTION
Always connect the system separator to
the water supply, never directly to the appli-
ance!
Use this high pressure cleaner exclusively
for
– Cleaning using low pressure jet and de-
tergent (for e.g. for cleaning machines,
cars, buildings, tools),
– For cleaning using high pressure jet
without detergent (for e.g. for cleaning
facades, terraces, garden appliances).
For stubborn dirt, we recommend the use of
the dirt blaster as a special accessory.
HD...Plus includes a dirt remover as part of
standard delivery.
Quality requirements for water:
ATTENTION
Only clean water may be used as high
pressure medium. Impurities will lead to in-
creased wear and tear or formation of de-
posits in the appliance.
If recycled water is used, the following limit
values must not be exceeded.
Safety devices serve for the protection of
the user and must not be put out of opera-
tion or bypassed with respect to their func-
tion.
While reducing the water supply/quantity
regulation at the pump head, the overflow
valve opens and part of the water flows
back to the pump suck side.
If the pulling lever on the trigger gun is re-
leased the pressure switch turns off the
pump, the high-pressure jet is stopped. If
the pulling lever is pulled the pump is
turned on again.
The safety valve opens when the permissi-
ble operating pressure is exceeded; water
flows back to the suction side of the pump.
The overflow valve, pressure switch and
safety valve are set and sealed at the fac-
tory.
Setting only by customer service.
