Start up

WARNING
Risk of injury! Appliance, accessories, sup-
ply lines and connections must be in fault-
free condition. If they are not in a perfect
state then the appliance must not be used.

Electrical connection

DANGER
Danger of injury by electric shock.
The appliance may only be connected to al-
ternating current.
Minimum fuse strength of the socket (see
Technical Data).
The highest allowed net impedance at the
electrical connection point (refer to techni-
cal data) is not to be exceeded. In case of
confusion regarding the power impedance
present on your connection, please contact
your utilities provider.
It is imperative to connect the appliance to
the electric mains by means of a plug. It is
forbidden to permanently connect the appli-
ance to the power supply. The plug serves
for the disconnection from the mains.
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.

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 (min. length
7.5 m, minimum diameter 1/2") to the
water connection point of the machine
and at the water supply point (for e.g. a
tap).
Note:
The supply hose is not included.

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.
