WARNING
Observe regulations of water supplier.
According to applicable regula-
tions, the appliance must never be
used on the drinking water net
without a system separator. A suit-
able system separator by KÄRCHER or al-
ternatively a system separator according to
EN 12729 type BA must be used.
Water that was flowing through a system
separator is considered non-drinkable.
"
CAUTION
Always connect the system separator to
the water supply, never directly to the appli-
ance!
Î Connect the supply hose to the water
connection point of the machine and at
the water supply point (for e.g. a tap).
Î Open the water supply.
Note:
The supply hose is not included.
! DANGER
Never suck in water from a drinking water
container. Never suck in liquids which con-
tain solvents like lacquer thinner, petrol, oil
or unfiltered water. The sealings within the
device are not solvent resistant. The spray
mist of solvents is highly inflammable, ex-
plosive and poisonous.
Î Connect suction hose (minimum diame-
ter 3/4“) with filter (accessory) to the
water connection point.
Î Set dosing value for detergent to "0".
Î Remove air from appliance before oper-
ation.
Note:
Do not use the Geka coupling (included in
delivery) for vacuuming operations! Not all
connector couplings are suitable for vacu-
uming operations (pump sucks air and
therefore does not build up pressure).
Î Open the water supply.
Î Start the engine according to the oper-
ating instructions of the engine manu-
facturer.
Î To dearate the appliance, unscrew the
nozzle and allow the appliance to run
until the water exits in a bubble-free
state.

zle again.
