THANK YOU FOR PURCHASING A KARCHER
PRESSURE WASHER
PLEASE READ THIS LEAFLET CAREFULLY
BEFORE OPERATING YOUR MACHINE.
WHATIS APRESSURE 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.
AKarcher 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 excellent 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.

If you have followed all the instructions so far, you are
now ready to have fun cleaning the KARCHER way!!!
•Turn on the supply water and press the Spray Gun lever (No. 8) until
the water flows freely and removes all air locks from the hoses
•You may now attach the Spray Lance (No. 6) or required accessory
to the Spray Gun
All accessories are bayonet fit, simply push in and twist
until they click into position !
•Once water is flowing through the machine, you may now switch
on your Karcher Pressure Washer using the Power Switch (No. 3)
WHEN USING YOUR KARCHER PRESSURE WASHER ON
THE HIGH PRESSURE SETTING, THE RECOMMENDED
WORKING DISTANCE BETWEEN THE NOZZLE AND THE
OBJECT OR SURFACE TO BE CLEANED IS 30 CM.

4.1 High Pressure Operation
•Ensure the Spray Lance with Vario Power Nozzle (No. 6) or the Spray
Lance with Dirt Blaster (No. 12) are attached securely to the Spray Gun
(No. 8).
•Set vario power nozzle to high pressure mode
"+".
•Aim the lance towards the object to be cleaned making sure the
recommended working distance is used for reference (See Page 9).
Release the safety ratchet on the Spray Gun and squeeze the trigger.
•Switch on the pressure washer (No. 2)
The pressurised water jet alone is capable of fulfilling most
cleaning tasks around the garden or on building work but
detergent and wash brush are advantageous when cleaning
vehicles or other paint finishes.
4.2 Low Pressure Operation
•Dilute the detergent in a suitable container to the required concentra-
tion before using. (The correct dilution is dependent on the degree of
soiling of surface and is best determined by experience).
•Hang the Detergent Suction Tube (No. 1) in the
Detergent Container.
•Set Vario Power Nozzle to low pressure mode "–".
Note: No detergent in high pressure mode
Note: the Dirt Blaster (No. 12) is not for use in low pressure operati-
on.
•Aim the Spray Gun towards the object to be cleaned, release the
Safety Ratchet on the Spray Gun and squeeze the trigger to apply
the detergent to the working area.
•Switch on the pressure washer (No. 2)
