5. IMPORTANT – CARE AND MAINTENANCE
To ensure prolonged life and trouble-free use of your
Karcher Pressure Washer we strongly recommend
that you always adopt the following procedures:
Water
• Before use, always check the inlet filter for dirt or debris.
• Visually check to see if the nozzle is blocked by dirt or grit, if so, re-
move the dirt from the nozzle hole with a needle and rinse with water
from the front.
Failure to do this will seriously damage your machine and invali-
date the warranty.
• Connect the water supply hose and, without the lance attached,
squeeze the trigger gun to run water through your pressure washer
until the water flow is constant. Then plug in to the electric supply.
• Unless drawing water from an open water source such as a water butt,
always have a minimum of 10 metres (25 feet) of uncoiled hose bet-
ween the water tap and your machine. The internal diameter of the
feed water hose should be 12 mm (1/2”).
• Water Regulations require the use of a back-flow preventer valve at
the tap end of the supply hose.
Only use a full flow connector to connect the hose to the machine.
Electricity
• If using an electrical extension lead it must be rated at a minimum of
13 amps.
• Always fully uncoil any extension lead when used.
Chemicals
Use of chemicals other than those recommended by Karcher could cau-
se significant damage which may not be covered by your warranty.
• After using chemicals, always run fresh water through your machine.
• The high pressure hose of your Karcher Pressure Washer should not
be mistreated. It is designed to withstand high pressure operation so
vehicles should NOT run over it, nor should it be pulled across sharp or
abrasive edges. These actions may weaken the hose and cause bal-
looning.
