Important – Care And Maintenance - Kärcher K 7.85 M Operating Instructions Manual

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 water inlet filter for dirt or debris.
• Visually check to see if the nozzle is blocked by dirt or grit, if so,
remove 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
invalidate the warranty.
• 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.
