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.
몇CAUTION
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.
When the maximum operating over pres-
sure is exceeded, the overlow valve opens
and the water flows back to the pump inlet.
The overflow valve and pressure switch are
set and sealed at the factory. Setting only
by customer service.

몇WARNING
Risk of injury! Appliance, accessories, sup-
ply lines and connections must be in fault-
free condition. If they are not in a perfect
state then the appliance must not be used.
몇DANGER
Danger of injury by electric shock.
–It is imperative to connect the appliance

case of confusion regarding the power
Environmental protection
The packaging material can be
recycled. Please do not throw
the packaging material into
household waste; please send it
for recycling.
Old appliances contain valuable
materials that can be recycled;
these should be sent for recy-
cling. Batteries, oil, and similar
substances must not enter the
environment. Please dispose of
your old appliances using appro-
priate collection systems.
