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.

the water flows freely and removes all air locks from the hoses.

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.4)

• You can choose between four modes of operation on the Spray

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.

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.

4.1 High Pressure Operation

• Switch on the pressure washer (No.4)

• Ensure the Spray Lance with the Four–Way Nozzle (No.14) is attached

securelytotheSprayGun(No.12)andthenozzleissettotherequiredjet.

• 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.13) on the Spray Gun and

squeeze the lever.

The pressurised water jet alone is capable of fulfiling 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 without Brush

• Fill the Detergent Tank (No.5) 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).

• Set the Four–Way Nozzle to the Low Pressure Jet ( ).

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.

• Switch on the pressure washer (No.4)

• Aim the nozzle towards the object to be cleaned,

release the Safety Locking Device on the Spray Gun

and squeeze the lever to apply the detergent to the

working area.
