Use the diagram on Page 6 for reference purposes.
3.2 Water Connection
• The minimum length of supply hosepipe advised for maximum user
convenience is 7.5 metres with a diameter of 12.5 mm (1/2") to allow
free flow of inlet water to the machine so avoiding backpressure and
any associated potential damage to your machine.
• Attach your supply hosepipe with its connector to the coupling on the
machine (No.10) and the other end should be connected to a suitable
water supply.
3.3 Electrical Connection
• Ensure the Power Switch (No.4) is in the “OFF” position before
connecting the factory fitted Plug attached to the Mains Electric Lead
(No.7) into an earthed socket. (it is recommended that an RCD plug
socket is used.)
If using an Extension Cable make sure it is completely unwound
from the cable drum and is the correct diameter.
3.4 SuctionMode-
anaddedbenefitoftheKarcherPressureWasher
• If you are drawing water from a static water supply such as a water
butt disconnect the water connection/hosepipe with coupling (No.10)
from the machine and replace with a suction hose and filter (Part
No. 4.440.238) that can be purchased as an accessory.
• Disconnect the Spray Lance from the Spray Gun.
• Allow the pressure washer to operate without the Spray Lance fitted
until water flows from the Spray Gun without bubbles.
• Re-connect the Spray Lance to the Spray Gun.
Dirt in the drawn water could damage your Pressure Washer !
To avoid this risk please use a suitable filter - Part No. 6.414.389.

Lance (No.14) by rotating the nozzle end until the symbol is aligned
with the marking on the spray lance (The marking on the spray lance
must be up during operation).
Low-pressure jet........................... for operating with detergent or for
cleaning with low pressure
High-pressure pencil jet .............. forespeciallystubbornspotsoiling
High-pressure fan jet ................... for large area soiling
High-pressure rotating pencil jet .. for stubborn large area soiling
ONLY ROTATE THE FOUR-WAY NOZZLE
WHEN THE TRIGGER GUN IS CLOSED
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. IT CAN BE CLOSER IF
REQUIRED FOR PATIOS OR MASONERY.
When cleaning painted surfaces, ensure that the paint is sound and
there are no signs or rusting or blistering.

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).

Always ensure the Spray Gun is closed before changing
the nozzle setting
• Set the Dosing Ring on the Detergent Suction Tube
(No.5) to the desired dosage.
