Electrical connection

DANGER
Danger of injury by electric shock.
– It is imperative to connect the appliance
to the electric mains by means of a plug.
It is forbidden to permanently connect
the appliance to the power supply. The
plug serves for the disconnection from
the mains.
– The appliance may only be connected
to alternating current.
– The highest allowed net impedance at
the electrical connection point (refer to
technical data) is not to be exceeded. In
case of confusion regarding the power
impedance present on your connection,
please contact your utilities provider.
– The plug and coupling of the extension
cable used must be watertight.
– Use the extension cord that has an ade-
quate cross-section (see "Technical Data")
and unwind it fully from the cable drum.
For connection values, see type plate/tech-
nical data.
 Unwind the mains cable and place it on
the floor.
 Insert the mains plug into a socket.

Water connection

Connection to the water supply
WARNING

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!
For connection values refer to technical
specifications
 Connect the supply hose (minimum
length 7.5 m, minimum diameter 1") to
the water connection point of the appli-
ance (such as the tap).
Note:
The supply hose is not included.
 Open the water supply.
Drawing in water from open reservoirs
 Screw the suction hose (order no. 4.440-
270.0) onto the water connection.
 Connect filter (order-no. 4.730-012.0) to
suction hose.
 Deaerate the appliance:
Unscrew the nozzle.
Switch on the appliance and let it run
until the water exiting is bubble-free.
At the end let the appliance run for ap-
prox. 10 seconds - then switch off. Re-
peat the procedure for a couple of
times.
 Switch off the appliance and fit the noz-
zle again.
DANGER

the spray pipe firmly with both hands.
Risk of injury! The trigger and safety lever
may not be locked during the operation.
Risk of injury! Contact Customer Service if
the safety lever is damaged.
Risk of injury from high-pressure water jet.
Slide the safety catch on the trigger gun for-
ward before performing any work with the
appliance.
CAUTION
Clean engines only at places with corre-
sponding oil separators (environmental
safety).
ATTENTION
Risk of blocking. Place the nozzles in the
accessory compartment with their joint
pointing upward.
