Working with detergent

Please use exclusively KÄRCHER deter-
gents and care products to carry out the re-
spective cleaning task, as these were
specifically developed for your appliance.
The use of other detergents and care prod-
ucts may lead to premature wear and can
invalidate your warranty claims. Please ob-
tain information at your local dealer or re-
quest information directly from KÄRCHER.
Notes regarding the detergent: The most
commonly used KÄRCHER detergents can
be purchased ready to use in their Plug 'n'
Clean detergent bottles with locking lids.
This will make the pesky refilling and filling
processes redundant.
Illustration
 Remove the lid from the Plug 'n' Clean
detergent bottle and press the deter-
gent bottle into the detergent connec-
tion with the opening facing down.
Illustration
 Adjust the suction volume of the deter-
gent solution by means of the dosage
regulator for detergents.
 Use spray lance with pressure regula-
tion (Vario Power).
 Turn the spray lance to "Mix" position.
Note: This will mix the detergent with
the water stream.
Recommended cleaning method
 Spray the detergent sparingly on the
dry surface and allow it to react, but not
to dry.
 Spray off loosened dirt with the high-
pressure jet.
