Good service work requires extensive and practice-
oriented training as well as well-structured training
materials.
Hence we offer regular basic and advanced training
programmes covering the entire product range for all
service engineers.
In addition to this, we also prepare service manuals
for important appliances - these can be initially used
as instruction guides and later on as reference
guides.
Apart from this, we also regular information about
product enhancements and their servicing.
If you should require supplements, have corrections
or questions regarding this document, please ad-
dress these citing the following subject to:
The responsible product specialist will take care of
your issue.

몇Warning
First remove the mains plug before doing any job on
the vacuum cleaner.
Safety devices serve to protect the user and must not
be rendered inoperational or their functions by-
passed.
Danger
Immediate danger that can cause severe injury or
even death.
몇Warning
Possible hazardous situation that could lead to se-
vere injury or even death.
Caution
Possible hazardous situation that could lead to mild
injury to persons or damage to property.
High-pressure jets can be dangerous if im-
properly used. The jet may not be directed
at persons, animals, live electrical equip-
ment or at the appliance itself. The high
pressure cleaner must only be used while
standing.
According to the applicable regulations, the
appliance must never be used on the drinking
water supply without a system separator. Use
a suitable system separator manufactured by
KÄRCHER; or, as an alternative, a system separator
as per EN 12729 Type BA. Water flowing through a
system separator is considered non-drinkable.
Caution
Always connect the system separator to the water
supply, never directly to the appliance!
This multi-purpose cleaning appliance is intended for
wet cleaning with or without detergent and to vacuum
up the wastewater.
This appliance is intended for inside use.
–Applying detergent solution with the low-pressure
jet.
–Removing dirt with the high pressure jet.
–Applying and vacuuming detergent solution with
the floor jet (accessory).
–Detergent suction with fine filter from free-standing
container
–Detergent suction via injector in vacuum.
The suction turbine creates a vacuum in the waste-
water reservoir.
The waste water is thus pumped from the floor nozzle
into the waste water reservoir through the suction
hose.
If the wastewater reservoir is full, the float closes the
suction opening.
The vacuum lips located on the floor nozzle can be
replaced without any tool.
The distance between the vacuum lip and the floor
can be adjusted without any tool.
