Î Push the high pressure hose into the trigger

gun until it locks audibly.

Note: Make sure the connection nipple is

aligned correctly.

Î Check the secure connection by pulling on

the high-pressure hose.

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.

Observe regulations of water supplier.

For connection values, see type plate/technical

data.

Î 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).

Î Screw the coupling element (supplied) to the

water connection on the appliance.

Î Push the water supply hose onto the cou-

pling unit, then connect it to the water supply.

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).

Î Fill the KÄRCHER suction hose with back-

flow valve with water, screw to water supply

and hang into the water butt.

Î Separate the high pressure hose from the

high pressure connection of the appliance.

Î Switch the appliance on (I/ON) for a max. of

2 minutes and wait until the water exits the

high-pressure connection without bubbles.

Î Turn off the appliance "0/OFF".

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".
