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)

• You can choose between two modes of operation on the Spray Lance

(No. 6) by rotating the nozzle end.

High Pressure setting .................. A 25° high pressure flat jet

Low Pressure setting ................... A low pressure jet, for operation

with detergent

ONLY ROTATE THE DOUBLE NOZZLE WHEN THE

TRIGGER GUN IS CLOSED

WHEN USING YOUR KARCHER PRESSURE WASHER ON

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.

4.1 High Pressure Operation

• EnsuretheSprayLancewiththeDoubleNozzle(No.6)ortheDirtBlaster

(No.12)areattached securelytotheSprayGun(No.8), also the double

nozzle is set to the required jet.

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 the nozzle to the Low Pressure Setting. Note that the Dirt Blaster

is not for use in Low pressure Operation.

Always ensure the Spray Gun is closed before changing

the nozzle setting

• Aim the nozzle towards the object to be cleaned, release the Safety

Locking Device on the Spray Gun and squeeze the trigger to apply the

detergent to the working area.

• Switch on the pressure washer (No.2)

• To rinse the detergent away, close the trigger, increase the nozzle set-

ting towards High Pressure setting. No detergent can be drawn in

with a high working pressure. Spray with the required jet spray set-

ting until no trace of detergent can be found.
