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.
AKarcherPressureWashercanbeusedforanendlesslistofapplications
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
suitablecoldwatersupplyalthoughsomemodelswillacceptawaterinlet
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.

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.10) until
the water flows freely and removes all air locks from the hoses
• You may now attach the High Pressure 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.2)
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.
ITCANBECLOSERIFREQUIREDFORPATIOSORMASONERY
It is your responsibility to check the suitability of the surface to be cleaned.
Karcher (UK) Ltd. cannot be held responsible for any damaged caused.

10
4.1 High Pressure Operation
• Ensure the High Pressure Lance (No.6) is attached securely to the
Spray Gun (No.10).
• 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 Lock Device (No.9) and squeeze the lever.
• Switch on the pressure washer (No.2)
Dirtblaster Lance (No.7)
A rapidly rotating pencil jet achieves a very high impact pressure so
that it has a very good cleaning effect. Use it to remove loose paint,
stubborn algae and moss from hard surfaces.
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
• Fill the Detergent Tank (No.12) with the selected detergent,
ensuring it is the correct concentration (See Page 8 or read
recommended dosage on label)
orDilute the detergent to the required concentration before filling the
Detergent Tank. (The correct dilution is dependent on the degree of
soiling of surface and is best determined by experience).
• Use the Spray Gun (10) without Spray Lance.
• Aim the Spray Gun towards the object to be cleaned, release the
Safety Lock Device (No.9) on the Spray Gun and squeeze the lever
to apply the detergent to the working area.
• Switch on the pressure washer (No.2)
• To rinse the detergent away, close the Spray Gun, attach the High
Pressure Lance (No.6). No detergent can be drawn in with a high
working pressure. Spray with the high pressure jet until no trace of
detergent can be found.

11
4.3 Low Pressure Operation with Brush (not included)
When cleaning surfaces with a grease contamination - typically car
paintwork that always has a greasy traffic film covering. Follow the
procedure of:
• Washing loose dirt away with the clean water high pressure spray.
• Apply the detergent in low pressure mode by removing the bayonet fit
spray lance and fitting the Washing Brush (Part No. 6.903-275) to the
Spray Gun.
• Leave for 2-4 minutes for the detergent to have maximum effect.
• With or without the pressure washer switched on, brush down the
surface being cleaned, this physical agitation removes all trace of
traffic film.
• Finally revert to the high pressure operation with the Spray Lance and
complete the wash down.
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.

12
4.4 End Of Operation
ALWAYS REMEMBER TO RINSE YOUR PRESSURE WASHER
AFTER USING DETERGENT BY FILLING THE DETERGENT
CONTAINER WITH CLEAN WATER AND RUN THE PUMP FOR
APPROXIMATELY ONE MINUTE
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.11) from the socket.
• Close the water inlet (tap) and disconnect the hosepipe.
•Squeeze the lever to remove all pressure from the machine.
Release the lever and then secure the lever with the Safety
Catch 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.

13
• 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
cause 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 HAS NOT BEEN COMPLETELY
EMPTIED OF WATER AFTER USE. ALWAYS STORE IN A
FROST FREE AREA.
