Please follow these instructions carefully
for troublefree cleaning.
Use the diagram on Page 6 for reference purposes.
3.2 Water Connection
• According to the applicable regulations, the appliance
must never be used on the drinking water net without a sy-
stem separator. Use a suitable system separator manu-
factured by Kärcher; or, as an alternative, a system separator as per
EN 12729 Type BA.
• 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.7) 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.14) 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 water connection/hosepipe with coupling (No.7)
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.
