RECOMMENDED FUEL
Use unleaded petrol with an octane
rating of 86 or higher. DO NOT overfill.
WARNING: ALWAYS REFUEL IN A WELL VENTILATED AREA AWAY FROM
ANY SOURCES OF IGNITION AND HEAT.
WARNING: ALLOW THE UNIT TO COOL DOWN BEFORE REFUELLING.
WARNING: DO NOT LEAVE FUEL WITHIN THE REACH OF CHILDREN.
PRESSURE REGULATOR
When supplied, the pressure
regulator may be set to minimum.
Turn the pressure regulator on the
pump fully clockwise to allow water
pressure to build up when the
pressure washer is running.
If you find the pressure is too high, you
can adjust this later by turning the
regulator counter clockwise.
Bypass mode: In bypass mode, the pump recirculates the water because the
trigger of the spray gun is not being pulled. If the unit is left in bypass mode for
more than two minutes, the water temperature will rise to a dangerous level
and could damage internal components of the pump.
NOTE: Any damage to the pump due to these causes will not be covered
under warranty.
Thermal Relief Valve: In an effort to
prevent damage, pumps are
equipped with a thermal relief valve.
This valve will open when the
temperature inside the pump
becomes too high. The valve will then
release a gush of water in an effort to
lower the temperature inside the
pump. Immediately after this occurs,
the valve will close.
STARTING YOUR POWER WASHER
Prior to starting, refer to your engine manual for proper starting procedures for
your engine type.
1. Make sure the engine has sufficient fuel. See page 10.

• Stand on a stable surface and grip the gun/spray wand firmly with
both hands.
• Expect the gun to kick when the trigger is pulled.
2. Release the trigger to stop water flow.
NOTE: The power washer will automatically go into bypass mode, In
bypass mode, the pump recirculates the water because the
trigger of the spray gun is not being pulled. If unit is left in bypass
mode for more than two minutes, the water temperature will rise
to a dangerous level and could damage internal components of
the pump.
WARNING: DO NOT ALLOW THE UNIT TO OPERATE IN BYPASS MODE FOR

For long term storage, the petrol tank should be drained before the fuel
deteriorates with time. Ensure that the engine is cold before draining the tank.
Remove the fuel tank cap and use a pump type syphon to drain the petrol
into an appropriate, clean container. DO NOT store petrol for long periods of
time.
Dispose of excess petrol in an environmentally safe way, ideally by re-using in
a vehicle. Your local recycling centre can advise you on the best method of
disposal. After the petrol tank has been drained, start the engine and allow it
to use any petrol that may remain in the engine or fuel pipe. Make sure that
the power washer has been thoroughly cleaned before storing it in a clean
dry place.
