Working with detergent

Please use exclusively KÄRCHER detergents
and care products to carry out the respective
cleaning task, as these were specifically de-
velopped for your appliance. The use of other
detergents and care products may lead to
premature wear and can invalidate your war-
ranty claims. Please obtain information at
your local dealer or request information direct-
ly from KÄRCHER.
Notes regarding the detergent: The most
commonly use detergents can be purchased
ready to use in their detergent reservoirs with
locking lids. This will make the pesky refilling
and filling processes redundant.

Remove the lid from the detergent reser-
voir and press the detergent reservoir into
the detergent connection with the opening

Illustration
Adjust the suction volume of the detergent
solution by means of the dosage regulator

Spray the detergent sparingly on the dry
surface and allow it to react, but not to dry.
