Water supply

Caution! Impurities in the intake water damage the

pump. To prevent this we expressly urge you to use

the Kärcher water filter (order no. 4.730-097).

The operation of the high-pressure cleaner with a clo-

sed water supply line causes damage to the cylinder

head unit. Please never operate the high-pressure

cleaner with a closed water supply tap.

The unit can either be supplied from the water main

or from water in an open container.

Water supply from the water main

• Connect a supply hose (not included) to the water

inlet of the unit and to the water supply (e.g. water

tap).

• Open the water supply.

Water supply from an open container

• Unscrew the coupling part for the water inlet.

• Screw the suction hose with filter (not included,

see “Special accessories”) onto the water connec-

tion of the unit.

• Hang the filter in the container.

• Vent the unit before operation.

– Unscrew the high-pressure line at the high-pres-

sure outlet of the unit.

– Switch on the unit and let it run until water free

of bubbles emerges at the high-pressure out-

let.

– Switch off the unit and screw on the high-pres-

sure hose again.

Preparation

• Insert power plug.

• Turn master switch to “I”.

Switching on

• Press safety button on the handgun and pull the

lever.

Switching off

• Release the lever.

During breaks in work and when leaving the unit

secure it against inadvertent switching on by pres-

sing the safety button.

Regulate operating pressure

Raise operating pressure:

twist spray lance in direction “+”.

Reduce operating pressure:

twist spray lance in direction “–”.

Adding the cleaning agent

• Draw the cleaning agent suction hose out of the

housing to the required length.

• Hang the cleaning agent suction hose in the cle-

aning agent container.

• Rotate the spray lance in the direction of “–” until

reaching the stop.

If cleaning agent has been added:

• Hang the cleaning agent suction hose in a container

of clear water, switch on the unit for about one mi-

nute and flush through.

Recommended cleaning method

1. Spray the cleaning agent on the dry surface spa-

ringly and let it react (but not dry out).

2. Wash off the loosened dirt with the high-pressu-

re jet.

Connect accessories

Depending on the model the following accessories

are either included in the scope of delivery or are

obtainable from specialist dealers (see also “Spe-

cial accessories”).

• Exchange the respective accessory with the spray

lance.

Wash brush

for large, smooth surfaces – e.g. on the automobile,

caravan or boat.Cleaning agent can be added.

Rotating wash brush

for gentle and thorough cleaning – e.g. bodywork and

glass surfaces.

Cleaning agent can be added.

Rotary nozzle

for stubborn accumulations of grime – e.g. moss-

covered promenade tiles or facades.

Work without cleaning agent and with the highest

operating pressure.

Finishing operations

• Master switch to “0”.

• Draw out power plug.

Water supplied from the water main

• Close the water supply tap.

Water supplied from an open container

inlet of the unit.

thout pressure.

inadvertent switching on.

Safekeeping

Caution! Frost can destroy an incompletely emp-

tied unit. In the winter keep the unit in a frost-free

room.

• Separate the spray lance from the handgun.

• Wind up the power cord and, for example, hang it

around the handgun.

Why do clouds of mist come out of top cover when in use? Is this normal? Submitted on 25-7-2024 at 11:50
