• Connect the water supply hose and, without the lance attached,
squeeze the Spray Gun lever 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
between 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
cause 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 HAS NOT BEEN COMPLETELY
EMPTIED OF WATER AFTER USE. ALWAYS STORE IN A
FROST FREE AREA.
