to start-up.
Illustration
Push the high pressure hose into the trigger
gun until it locks audibly.
Note: Make sure the connection nipple is
aligned correctly.
Check the secure connection by pulling on
the high-pressure hose.
Water supply
According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply with-
out 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 sys-
tem separator is considered non-drinkable.
Note: Impurities in the water can damage the
high-pressure pump and accessories. For pro-
tection, the use of the KÄRCHER water filter (op-
tional accessory, order no. 4.730-059) is
recommended.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/technical
data.
Use a fibre-reinforced water hose (not in-
cluded) with a standard coupling. (Minimum
diameter 1/2 inch (13 mm), minimum length
7.5 m).
Screw the coupling element (supplied) to the
water connection on the appliance.
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 backflow valve
(Optional accessory, order no. 4.440-238) to
draw in surface water, e.g. from water butts or
ponds (see specifications for max. suction
height).
Fill the KÄRCHER suction hose with back-
flow valve with water, screw to water supply
and hang into the water butt.
Separate the high pressure hose from the
high pressure connection of the appliance.
Switch the appliance on (I/ON) for a max. of
2 minutes and wait until the water exits the
high-pressure connection without bubbles.
Turn off the appliance "0/OFF".
Start up
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 min-
utes, switch it off and proceed as instructed in
the Chapter "Troubleshooting".
