Danger of injury!
Owing to the water jet emerging from the
high-pressure nozzle a recoil force opera-
tes on the handgun. Ensure you have a
secure footing and hold the handgun and
spray lance firmly.
If necessary wear protective clothing for
protection against return spray.
Water supply
Caution! Impurities in the intake water
damage the pump. To prevent this we ex-
pressly urge you to use the Kärcher water
filter (not included, order no. 4.730-097).
The operation of the high-pressure clea-
ner with a closed water supply line causes
damage to the pump. Please never ope-
