6 English
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 con-
sidered non-drinkable.
Observe regulations of water supplier.
For connection values, see type plate/tech-
nical data.
Î Use a fibre-reinforced water hose (not
included) with a standard coupling.
(Minimum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
Î Screw the coupling element (supplied)
to the water connection on the appli-
ance.
Î Push the water supply hose onto the
coupling unit, then connect it to the wa-
ter supply.
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).
Î Fill the KÄRCHER suction hose with
backflow valve with water, screw to wa-
ter supply and hang into the water butt.
Î Appliance ventilation: Switch the appli-
ance on with the high-pressure hose
detached and operate (max. 2 minutes)
until the water exits the high-pressure
connection without bubbles. Switch off
appliance and reconnect high-pressure
hose.
Mount loose parts delivered with appliance
prior to start-up.

Caution
Dry runs lasting longer than two minutes
