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.

2. SAFETY INSTRUCTIONS
Electrical Connection
Never use defect connection or e tension lines! If the connection line
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.
The appliance may only be connected to an electrical connection that
was performed by an electrician according to IEC 60364.
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 specifically
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.

4. OPERATING YOUR PRESSURE WASHER
If y u have f ll wed all the instructi ns s far, y u are
n w ready t 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 Dirtblaster Lance (No.7) or required
accessory to the Spray Gun.
All access ries are bay net fit, simply push in and twist
until they click int p siti n !
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 NO LE AND THE
OBJECT OR SURFACE TO BE CLEANED IS 30 CM.
IT CAN BE CLOSER IF REQUIRED FOR PATIOS OR MASONERY
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.

12
4.1 High ressure
 Ensure the Dirtblaster Lance (No.7) 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 11).
Release the Safety Lock Device (No.9) and squeeze the lever.
 Switch on the pressure washer (No.3)
The pressurised water jet al ne is capable f fulfilling m st
cleaning tasks ar und the garden r n building w rk but
detergent and wash brush are advantage us when cleaning
vehicles r ther paint finishes.
4.2 Low ressure 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 e perience).
 Hang the Detergent Suction Tube (No.2) in the Detergent container.
 Use the Spray Gun (No.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.3)
 To rinse the detergent away, close the Spray Gun, attach the Dirtblaster
Lance (No.7). 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.

13
4.3 Low ressure Operation with Brush (not included)
When cleaning surfaces with a grease contamination - typically car paint-
work 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 ma imum 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 rec mmend the f ll wing cleaning meth d:
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.

14
4.4 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 asher, always switch off the pump to avoid
damage due to overheating.
 Switch off the pressure washer by the Power Switch (No.3) 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
Locking Device to prevent accidental opening.
5. IMPORTANT  CARE AND MAINTENANCE
T ensure pr l nged life and tr uble-free use f y ur
Karcher Pressure Washer we str ngly rec mmend
that y u always ad pt the f ll wing pr cedures:
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
invalidate the warranty.

15
 Connect the water supply hose and, without the lance attached,
squeeze the Spray Gun lever 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 e tension lead it must be rated at a minimum of 13
amps.
 Always fully uncoil any e tension 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.
