Page 11
DESIGN FEATURES
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 MACHINE
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 the 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. Set the engine switch to ‘ON’.
11
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

position.
6. If you are starting the power
washer ‘cold’ set the choke lever
to the CHOKE position (left). If the
power washer is warm skip this
step.
7. Set the throttle to the 1/3rd of the
way towards the fast setting.
8. Pull the starting handle lightly until
you start to feel resistance and
then pull up sharply to start the
power washer.

Page 13
USING THE POWER WASHER
1. Pull the trigger on the gun to start water flow.
• 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 trigger to stop the 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 the unit is left in
bypass mode for more than two minutes, the water temperature
will rise to a dangerous level and could damage the internal
components of the pump.
WARNING: DO NOT ALLOW THE 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.

1. Adjust the pressure regulator on
the pump. Turn the pressure
regulator knob counter clockwise
to lower pressure. Once you have
finished work, 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. Slow the engine down and the water
pressure will drop.
4. Adjust the spray to a wider angle.
5. Slide the nozzle forward for low pressure and backwards for high pressure.

3. Store all other parts so that they are protected from damage.
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 using
elsewhere. 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.
