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.
ƽ
Danger
– Check whether the voltage indicated on
the type plate corresponds to the volt-
age of the socket.
– Unsuitable electrical extension cables
can be hazardous. Only use electrical
extension cables outdoors which have
been approved and labelled for this pur-
pose and have an adequate cable
cross-section:
1 - 10 m: 4 mm
2
10 - 30 m: 6 mm 2
With this appliance model, the matching
mains plug must be installed onto the
mains connecting line by an electrician.

Warning
Observe regulations of water supplier.
According to the applicable regula-
tions, 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 con-
sidered non-drinkable.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!
Quality requirements for water:
For connection values, see type plate/tech-
nical data.

Use a fibre-reinforced hose (not includ-
ed in standard delivery).
Diameter should be minimum 1".
 Connect the hose to the water connec-
tion of the appliance.
 Connect the hose to the water tap.
A prepressure pump must be connected in
front of the appliance to suction waer.
ƽ
Danger
Never suck in water from a drinking water
container.
ƽ
Danger
Never draw in fluids containing solvents or
undiluted acids and solvents! This includes
petrol, paint thinner and heating oil. The
spray mist thus generated is highly inflam-
mable, explosive and poisonous. Do not
use acetone, undiluted acids and solvents
as they are aggressive towards the materi-
als from which the appliance is made.
