quick connect end of hose to base of
spray gun.
6.4.1. Pull down on collar of quick connect,
slide onto spray gun and let go of collar.
6.4.2. Tug on hose to be sure of tight
connection.
6.5. NEVER connect high pressure hose to nozzle extension.
6.5.1. Keep high pressure hose connected to pump and spray gun while system is pressurized.
6.5.2. Always make sure that the spray gun, nozzles and accessories are correctly attached.
6.6. Attach other end of high pressure hose to high pressure outlet (A) on pump.
6.6.1. Pull down on collar of quick connect, slide onto pump and let go of collar.
6.6.2. Pull on hose to be sure of tight connection.
A = High Pressure Outlet. B = Water Supply Inlet. C = Detergent adapter and syphon tube.
6.6.3. The detergent adapter and syphon tube (C) need only be fitted when required.
IMPORTANT
You must flush the detergent siphoning system after each use by placing the filter into a bucket
of clean water, then run the pressure washer in low pressure for 1-2 minutes.
The high pressure stream of water that this equipment produces
can cut through skin and its underlying tissues, leading to serious
injury and possible amputation.
Contact with chemicals can cause bodily injury and/or property damage.
NEVER use caustic liquid with the pressure washer.
Use ONLY pressure washer safe detergent/soaps.
Follow all of the manufacturer’s instructions.

6.7. Turn Water Supply on, point gun in a safe direction and squeeze the trigger to purge the
pump of air and debris.
6.7.1. Do this for at least 30 seconds.
6.8. Take a look at all connections to make sure there are no leaks or loose connections.
IMPORTANT
DO NOT siphon standing water for the water supply.
Use ONLY cold water (less than 100°F).
6.9. Connect the garden hose to the water inlet.
6.9.1. Tighten by hand.
With the pressure washer working as normal, it is not advisable to reduce the
pressure on the unloader valve (by twisting adjuster anti-clockwise) for long
periods of time, as this redirects a proportion of the water flow back through
the by-pass system, which increases the temperature of the pump. If the
pressure is too high, it can be reduced slightly by reducing engine speed
marginally (from 3400rpm max to around 2800rpm). If the pressure needs to
be reduced further, it is recommended to use a larger nozzle size to reduce the
pressure.
If the nozzle size is too small, it will reduce the water flow and activate the by-
pass system, which will reduce the pump life, as it will run at a higher
temperature.
The pressure washer pump will move the same volume of water whatever the
pressure. The pressure is created by the size of the nozzle. The smaller the
nozzle the higher the pressure. It is important not to go too small as this will
reduce flow, which reduces cleaning efficiency and pump lifespan.
6.10. Starting the engine (RECOIL STARTING). For full engine starting and stopping details see
supplied engine manual.
6.10.1. MAKE sure that the pre-operation checks have been carried out.
6.10.2. Turn the fuel cock (1) is turned ON.
6.10.3. To start the engine, locate the engine speed switch on the side of the engine. Undo
the knob (1) in an anti-clockwise direction (2) and the slide in to the down (RUN) position (3)
and switch it to the ON position. Once in RUN position (3) turn the knob (1) in a clockwise
direction (4) to lock it in position.
NEVER use a starting aid such as ether. Engine damage will occur.

6.10.4. Grasp the recoil starter handle (1).
6.10.5. Pull the handle out slowly until you feel strong resistance, slowly return the recoil
starter handle to the initial position.
6.10.6. Push the decompression lever down (1) and release it. The decompression lever will
automatically return to the original position when the engine starts.
6.10.7. Grasp the recoil starter handle and pull it out with a strong and even motion using
both hands if required. Slowly return the recoils starter handle to initial position.
6.10.8. If the engine does not start repeat from 6.10.
6.11. Starting the engine (ELECTRIC STARTING). For full engine starting and stopping details see
supplied engine manual.
6.11.1. Follow steps 6.10.1. to 6.10.3.
6.11.2. Insert key into key-switch (1), turn key in a clockwise direction to the START position. Release
the key as soon as the engine starts. The key-switch will return to the ON position, in the ON
position the ignition indicator lamp (2) will be ON (except when the engine is running).

6.11.3. If the engine fails to start;
6.11.3.1. Wait until the engine comes to a complete stop before you attempt to start it again.
Engaging the starter when the engine is still rotating will result in damage to the starter motor
and flywheel.
6.11.3.2. Wait at least 30 seconds before you attempt to start the engine again. This pause will
allow the battery to recover and to prevent damage to the starter motor due to a low battery
voltage.
6.12. Shutting down the engine.
6.12.1. Before shutting down the engine you MUST release the pressure in the wand by pulling the
trigger. ALWAYS point the spray gun in a safe direction, squeeze the spray gun trigger to
release the retained high water pressure. Once pressure is released shut down the engine.
IMPORTANT
The spray gun traps high water pressure, even when the engine has stopped and water
disconnected.
The couplings will not release if they are under pressure. To release hoses and coupling ALWAYS
de- pressurise by operating the trigger.
6.12.2. Run the engine at low idle speed or run without load for at least 5 minutes before you shut it
down.
6.12.3. To stop the engine.
6.12.3.1. Turn the key-switch to the off position or;
6.12.3.2. Locate the engine speed switch on the side of the engine. Undo the knob
