Water supply

Caution
Impurities in the water can damage the
high-pressure pump and the accessories.
For protection, the use of the KÄRCHER
water filter (optional accessory, order no.
4.730-059) is recommended.
For connection values, see type plate/tech-
nical data.
Observe regulations of water supplier.
Water supply from mains
Warning
According to applicable regulations, the ap-
pliance must never be used on the drinking
water net without a system separator. A
suitable system separator by KÄRCHER or
alternatively a system separator according
to EN 12729 type BA must be used.
Water that has flown through a system sep-
arator is no longer classified as drinking
water.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!
Illustration
 Screw the coupling element to the wa-
ter connection on the appliance.
Drawing in water from open reservoirs
This high-pressure cleaner is suited to work
with the KÄRCHER suction hose with back-
flow valve (Optional accessory, order no.
4.440-238) to draw in surface water, e.g.
from water butts or ponds (see specifica-
tions for max. suction height).
 Fill the suction hose with water.
 Screw the suction hose into the water
connection of the appliance and insert it
into the water source (e.g. rainwater
drum).
Caution
Dry running of more than 2 minutes leads to
damage of the high-pressure pump. If the
appliance does not build up pressure within
2 minutes, switch the appliance off and pro-
ceed in accordance with the instructions in
Chapter "Troubleshooting".
Illustration
 Unwind the high pressure hose com-
pletely from the hose drum. Hold on to
the transport handle during this proce-
dure.
Note: If the hand crank is in its secured
position, fold it up first.
