• 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 12mm (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
ballooning.
IMPORTANT
REMEMBER FROST WILL DAMAGE YOUR KARCHER
PRESSURE WASHER IF IT HS NOT BEEN COMPLETELY EMP-
TIED OF WATER AFTER USE. ALWAYS STORE IN A FROST
FREE AREA.
