THANK YOU FOR PURCHASING A KARCHER
PRESSURE WASHER
PLEASE READ THIS LEAFLET CAREFULLY
BEFORE OPERATING YOUR MACHINE.
WHAT IS A PRESSURE WASHER?
A Pressure Washer is essentially a powerful electric motor driving a set
of pistons that force water through a small nozzle, thus creating a
pressurised jet of water. This provides the cleaning power behind the
Karcher Pressure Washer.
A Karcher Pressure Washer can be used for an endless list of applications
around the home and garden. It provides an efficient, economical and
labour saving way of cleaning with e cellent results.
All Karcher domestic pressure washers are designed to run from a
suitable cold water supply although some models will accept a water inlet
temperature of between 40 °C and 60 °C.
Environmental Comment - Save water with high pressure.
The Karcher Pressure Washer is environmentally friendly enabling you
to reduce your water consumption compared to a normal garden hose.
A definite advantage with a metered water supply
OR
with the added benefit of suction mode, water can be drawn from an
open container such as a water butt.

is damaged, it must be replaced with a special connection line that is
available from the manufacturer or his customer service.
Please make sure that the connection or e tension lines are not
damaged by being ran over, pulled or dragged. Protect the
connection lines from heat, oil, and sharp edges.
Never touch the mains plug and the socket with wet hands.
The connection between connection line and e tension line must not
lie in the water.
All current-carrying components within the working area must be
jet-proof.

 Only connect the appliance to alternating current. The voltage must
comply with the voltage specified on the typeplate.
 To avoid electric accidents, we recommend to use sockets with a
series connected residual current operated device (rated breaking
current ma . 30 mA).
Warning: Inappropriate e tension lines may be dangerous. If you
work outside, only use e tension lines that are approved and specifi-
cally labelled and provide of a sufficient conductor cross section:
1 to 10 m: 1.5 mm² 10 to 30 m: 2.5 mm²
 The plug and the coupling of an e tension line must be waterproof.
 Always unwind the e tension line completely from the cable drum.
