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 the applicable regu-
lations, the appliance must never 
be used on the drinking water net 

without a system separator. Use a suitable 
system separator manufactured by Kärch-
er; or, as an alternative, a system separator 
as per EN 12729 Type BA.
Water flowing through a system separator 
is considered non-drinkable.

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.

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.

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.
