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.
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.
Observe regulations of water supplier.
For connection values, see type plate/tech-
nical data.
 Use a fibre-reinforced water hose (not

(Minimum diameter 1/2 inch (13 mm),
minimum length 7.5 m).

ter connection on the appliance.

This high-pressure cleaner is suited to work
with the KÄRCHER suction hose with back-
flow valve (Optional accessory, order no.

from water butts or ponds (see specifica-
tions for max. suction height).

backflow valve with water, screw to wa-
ter supply and hang into the water butt.
 Separate the high pressure hose from
the high pressure connection of the ap-
pliance.
 Switch the appliance on (I/ON) for a
max. of 2 minutes and wait until the wa-
ter exits the high-pressure connection
without bubbles.
 Turn off the appliance "0/OFF".
