Water supply

According to the applica-
ble regulations, the appli-
ance must never be used
on the drinking water supply
without a system separator. Use
a suitable system separator
manufactured by KÄRCHER; or,
as an alternative, a system sep-
arator as per EN 12729 Type
BA.
Water flowing through a system
separator is considered non-
drinkable.
Caution
Always connect the system sep-
arator to the water supply, never
directly to the appliance!
Note: Impurities in the water can dam-
age the high-pressure pump and ac-
cessories. For protection, the use of
the KÄRCHER water filter (optional ac-
cessory, order no. 4.730-059) is rec-
ommended.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/
technical data.

Use a fibre-reinforced water hose
(not included) with a standard cou-
pling. (Minimum diameter 1/2 inch
(13 mm), minimum length 7.5 m).
Illustration

Screw the coupling element to the
water connection on the appliance.

Push the water supply hose onto
the coupling unit, then connect it to
the water supply.
Drawing in water from open
reservoirs
This high-pressure cleaner is suited to
work with the KÄRCHER suction hose
with backflow valve (Optional accesso-
ry, order no. 4.440-238) to draw in sur-
face water, e.g. from water butts or
ponds (see specifications for max. suc-
tion height).

Fill the KÄRCHER suction hose
with backflow valve with water,
screw to water supply and hang into
the water butt.

Remove air from appliance before
operation.
Switch on the appliance without
connection the high-pressure hose
(max. 2 minutes) and run it until the
water discharging from the high-
pressure outlet is free of bubbles.
Switch off appliance and reconnect
high-pressure hose.
Caution
Dry runs lasting longer than two
minutes lead to damages to the
high pressure pump. If the appli-
ance does not build up pressure
within two minutes, switch it off
and proceed as instructed in the
Chapter "Troubleshooting".
Illustration

Insert the high pressure hose tightly
into the quick coupling on the appli-
ance, it will lock in audibly.

Note: Make sure the connection

nipple is aligned correctly.



Check the secure connection by

pulling on the high pressure hose.
