WARNING: TAKE CARE NOT TO TOUCH ANY HOT PARTS OF THE POWER
WASHER WHEN CHECKING THE OIL LEVELS.
IMPORTANT: The engine is supplied without any oil in it and must be filled to
the correct level before use, see below.
CHECKING THE PUMP OIL LEVEL
Look at the sight glass on the pump
to check the oil level inside.
If required, remove the oil filler cap
and top up with oil.
• We recommend the use of
SAE30 oil in this pump.
CHECKING THE ENGINE OIL LEVEL
1. Turn the oil filler cap/dipstick anticlockwise and remove it from the

2. Just inside the fuel tank is a fuel strainer
remove any contaminants which may have accumulated.
3. Refuel in a well-ventilated area,
before starting the engine. If the
engine has been running, allow it
to cool. Refuel carefully to avoid
spilling fuel. Do not fill above the
fuel strainer shoulder.
4. After refueling, Replace the fuel
filler cap securely.
. Check this filter periodically and

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.

USING YOUR POWER WASHER
POWER WASHER TERMINOLOGY
PSI: Pounds per square inch, the unit of measurement for water pressure.
GPM: Gallons per minute.
CU: Cleaning units, GPM x PSI.
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.
NOTE: Any damage to the pump due to these causes will not be
covered under warranty.
Thermal Relief Valve: In an effort to prevent extreme damage, pumps are
equipped with a thermal relief valve. This valve will open when the
temperature inside the pump becomes too high. This 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.
Chemical Injection System: This mixes cleaners or cleaning solvents with the
pressurised water to improve cleaning effectiveness.

STARTING THE 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.
2. Check engine oil level. See page 9.
3. Turn water supply on.
WARNING: FAILURE TO TURN ON THE WATER COULD CAUSE DAMAGE TO
THE PUMP.
4. Start the engine. See Engine Owners Manual for correct procedure.
NOTE: If the engine does not start after two pulls, pull the trigger on the
gun to relieve the pressure.
5. Pull the trigger on the gun to start water flow.
• Stand on a stable surface and grip gun/spray wand firmly with both
hands.
• Expect the gun to kick when the trigger is pulled.
6. Release 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 UNIT TO OPERATE IN BYPASS MODE FOR
MORE THAN TWO MINUTES AT ANY TIME.

ADJUSTING THE SPRAY
The nozzle is adjustable to allow you to change the spray from a narrow jet of
water to a wide spray.
To adjust the nozzle, proceed as follows.
1. Hold the shaft of the lance in one hand.
2. Twist the nozzle with the other hand.
3. To vary the spray between narrow and wide, turn the nozzle counterclockwise
through a half-of-a-turn.
ADJUSTING THE PRESSURE
1. Adjust the pressure regulator on
the pump. Turn the pressure
regulator
to lower pressure. Once you have
finished using your power washer,
return the pressure regulator to its
original position.
2. Back away from the surface to be
cleaned. The further away you
are the less the pressure will be on
the surface being cleaned.
3. Reduce the speed of the engine (RPM). Slow the engine down and the
water pressure will also go down.
4. Adjust the spray to a wider angle.
5. Slide the nozzle forward for low pressure
knob counter clockwise
and backwards for high pressure.

1. Shut off the power washer and turn off the water supply.
2. Pull the trigger on the gun handle to relieve any water pressure.
3. Disconnect the spray wand from the gun.
4. Remove any obstructions and back flush with clean water.
5. Direct the water supply into the spray wand end for 30 seconds to back
flush loosened particles.
6. Reconnect the spray wand to the gun and turn on the water supply.
CLEANING THE WATER INLET

STORAGE
ENGINE
See the separate engine manual supplied for information regarding the storage
procedure.
PUMP
1. Drain all water from the high pressure hose, coil it and store it on the gun/
hose holder located on the side of the power washer handle.
2. Drain all water from the spray gun and spray wand by holding the gun/
wand vertically with the nozzle pointing down and pulling the trigger. Store
in the gun/hose holder.
3. Store all other parts so that they are protected from damage.
STORAGE PROCEDURE
For long term storage, the petrol tank should be drained. 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. 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.
