BEFORE USE
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
1. Look at the sight glass on the
pump to check the oil level inside.
• The oil should be half way up
the sight glass.
2. If required, top up with oil. See
“Changing the pump oil” on
page 18.
• We recommend the use of
10W-SAE30 oil in this pump.
CHECKING THE ENGINE OIL LEVEL
1. Turn the oil filler cap/dipstick anti-
clockwise and remove it from the
oil filler tube.
2. Wipe the oil filler cap/dipstick with
aclean cloth.
3. Insert the oil filler cap/dipstick
back into the oil filler tube and
then remove it again. Do not
screw it in when doing this.
WARNING: TO CARRY OUT THIS CHECK, PLACE THE POWER WASHER ON
LEVEL GROUND WITH THE ENGINE SWITCHED OFF.
WARNING: TAKE CARE NOT TO TOUCH ANY HOT PARTS OF THE POWER
WASHER WHEN CHECKING THE OIL LEVELS.

10
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
4. If the oil is low, fill the oil reservoir to
the edge of the oil filler hole.
• We recommend the use of
10W-SAE30 oil in the engine.
5. Replace the oil filler cap.
CHECKING THE FUEL LEVEL
1. To check the fuel level, remove the fuel tank cap.
2. Just inside the fuel tank is a fuel strainer. Check this filter periodically and
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.
RECOMMENDED FUEL
Use unleaded petrol with an octane
rating of 86 or higher. Do not overfill.
CAUTION: RUNNING THE
ENGINE WITH INSUFFICIENT OIL
WILL CAUSE ENGINE DAMAGE.
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.
SAFETY FEATURES
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.

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 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.
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 spray wand in one hand.
2. Twist the nozzle with the other hand.
3. To vary the spray between narrow and wide, turn the nozzle counter-
clockwise through a half-of-a-turn.
• Slide the nozzle forward for low pressure and backwards for high
pressure.
WARNING: DO NOT ALLOW THE UNIT TO OPERATE IN BYPASS MODE FOR
MORE THAN TWO MINUTES AT ANY TIME.

ADJUSTING THE PRESSURE
There are 4 ways to adjust the pressure.
1. Adjust the pressure regulator on
the pump. Turn the pressure
regulator knob counter clockwise
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.
• Slide the nozzle forward for low pressure and backwards for high
pressure.
APPLYING DETERGENTS AND CLEANING SOLVENTS
