machine corresponds with that of the power source
• The insulation of the supply cable is not damaged
• Only earthed sockets should be used
• If you are using an extension cable it must be completely unwound
from the cable drum and be the correct diameter:
10 meter length of cable should have a cross section of 1.5 mm²

4. OPERATING YOUR PRESSURE WASHER
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

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)

We recommend the following cleaning method:
Step 1:
Remove loose dirt by washing over the surface to be cleaned with the
high pressure jet.
Step 2:
Spray on the detergent and leave for 1-4 minutes, so assisting the easy
removal of fine dirt and associated greasy adhesions.
Step 3:
Finally, spray off the loosened dirt with the high pressure spray.
4.3 End Of Operation
ALWAYS REMEMBER TO RINSE YOUR PRESSURE WASHER
AFTER USING DETERGENT BY HANGING THE DETERGENT
SUCTION TUBE IN A CONTAINER WITH CLEAN WATER AND
RUN THE PUMP FOR APPROXIMATELY ONE MINUTE IN LOW
PRESSURE SETTING.
In the event of a break of 5 minutes in the operation of your
Karcher Pressure Washer, always switch off the pump to avoid
damage due to overheating.
• Switch off the pressure washer by the Power Switch (No. 2) and
unplug the Mains Electric Lead (No. 9) from the socket
• Close the water inlet (tap) and disconnect the hosepipe
• Release the trigger to remove all pressure from the machine
and then secure the trigger with the Safety Ratchet to prevent
accidental opening.

5. IMPORTANT – CARE AND MAINTENANCE
To ensure prolonged life and trouble-free use of your
Karcher Pressure Washer we strongly recommend
that you always adopt the following procedures:
Water
• Before use, always check the inlet filter for dirt or debris.
• Visually check to see if the nozzle is blocked by dirt or grit, if so, re-
move the dirt from the nozzle hole with a needle and rinse with water
from the front.
Failure to do this will seriously damage your machine and invali-
date the warranty.
• Connect the water supply hose and, without the lance attached,
squeeze the trigger gun to run water through your pressure washer
until the water flow is constant. Then plug in to the electric supply.
• Unless drawing water from an open water source such as a water
butt, always have a minimum of 10 metres (25 feet) of uncoiled hose
between the water tap and your machine. The internal diameter of
the feed water hose should be 12 mm (1/2”).
• Water Regulations require the use of a back-flow preventer valve at
the tap end of the supply hose.
Only use a full flow connector to connect the hose to the machine.
Electricity
• If using an electrical extension lead it must be rated at a minimum of
13 amps.
• Always fully uncoil any extension lead when used.
Chemicals
Use of chemicals other than those recommended by Karcher could cau-
se significant damage which may not be covered by your warranty.
• After using chemicals, always run fresh water through your machine.

• The high pressure hose of your Karcher Pressure Washer should not
be mistreated. It is designed to withstand high pressure operation so
vehicles should NOT run over it, nor should it be pulled across sharp
or abrasive edges. These actions may weaken the hose and cause
ballooning.
IMPORTANT
REMEMBER FROST WILL DAMAGE YOUR KARCHER
PRESSURE WASHER IF IT HS NOT BEEN COMPLETELY
EMPTIED OF WATER AFTER USE. ALWAYS STORE IN A
FROST FREE AREA.
