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.

max. of 2 minutes and wait until the wa-
ter exits the high-pressure connection

Caution
Dry runs lasting longer than two minutes
lead to damages to the high pressure
pump. If the appliance does not build up
pressure within two minutes, switch it off
and proceed as instructed in the Chapter
"Troubleshooting".
