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.

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.
