According to the applicable regula-
tions, the appliance 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
separator as per EN 12729 Type BA. Water
flowing through a system separator is consid-
ered non-drinkable.
Caution
Always connect the system separator to the
water supply, never directly to the appliance!
Note: Impurities in the water can damage
the high-pressure pump and accessories.
For protection, the use of the KÄRCHER
water filter (optional accessory, order no.
4.730-059) is recommended.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/tech-
nical data.
 Screw the coupling element to the wa-
ter connection on the appliance.
 Use a fibre-reinforced water hose (not
included) with a standard coupling.
(Minimum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
 Push the water supply hose onto the cou-
pling 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 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 KÄRCHER suction hose with
backflow valve with water, screw to wa-
ter supply and hang into the water butt.
 Remove air from appliance before oper-
ation.
Switch on the appliance without con-
nection the high-pressure hose (max. 2
minutes) and run it until the water dis-
charging from the high-pressure outlet
is free of bubbles. Switch off appliance
and reconnect high-pressure hose.
 Turn off the appliance "0/OFF".
