Kärcher 520 MH, Operating Instructions Manual

7

Please follow these instructions carefully

for troublefree cleaning.

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.11) and the other end should be connected to a suitable
water supply.

3.3 Electrical Connection

• Ensure the Power Switch (No.13) is in the “OFF” position before

connecting the factory fitted Plug attached to the Mains Electric Lead
(No.10) 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 Suction Mode - 

an added benefit of the Karcher Pressure Washer

• If you are drawing water from a static water supply such as a water

butt disconnect the high pressure hose from the machine.

• Disconnect the water connection/hosepipe with coupling (No.11)

from the machine and replace with a suction hose and filter (Part
No. 4.440.238) that can be purchased as an accessory.

• Allow the pressure washer to operate without the high pressure hose

fitted until water flows from the high pressure outlet without bubbles.

• Re-connect the high pressure hose to the high pressure outlet.

Dirt in the drawn water could damage your Pressure Washer !

To avoid this risk please use a suitable filter - Part No. 6.414.389.
