Caution
Car tyres, paint or sensitive surfaces such
as wood should not be cleaned with the dirt
blaster, as there is a risk of damage.
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 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.

ervoir and press the detergent reservoir
