SERVICE
Have your pressure washer serviced by a qualified repair person using only factory approved
replacement parts. This will ensure that the safety of the pressure washer is maintained. Incorrectly
fitted parts will void your warranty.
The equipment may only be used, maintained or repaired by those persons who understand and have
been instructed about the potential dangers. Independent changes in the equipment cancel any
manufacturer’s liability for any damages that result from these changes.
APPROPRIATE USE
Use the equipment only when it is in technically perfect condition and only for appropriate jobs, with an
awareness of safety and possible dangers, based on observation of the operating instructions. In
particular, problems which could influence the operational safety must be dealt with immediately.
All of the manufacture’s safety, work and maintenance regulations as well as the given norms in the
Technical Data must be observed.
STATIC ELECTRICITY AND FILLING THE PETROL TANK
Static electricity can initiate from un-grounded petrol tanks or containers from flowing petrol and
persons carrying a static electric charge. Static electricity can explosively ignite petrol vapours that are
present during the fuelling process, resulting in serious burns to nearby persons.
Many objects can accumulate and retain a static electric charge. Objects made of non-conductive
materials (eg. plastics) easily accumulate and retain static electrical charge, as can objects made of
conductive material (eg. metal, water) if they are not electrically grounded.
To avoid static electricity while fuelling, certain steps must be followed before and during the fuelling
process in order to minimise and safely dissipate static charge build-up:
Touch a grounded metal object before starting. Always dissipate static charge from your body before
beginning the fuelling process by touching a grounded metal object at a safe distance away from the
fuel source.

6
Use a portable container to fill the tank. NEVER fill the engine’s petrol tank directly from the fuel pump –
the engine’s tank is not grounded and the high velocity flow of petrol from a fuel pump can cause static
electric build-up. Use an approved portable container to transfer to the engine’s tank.
TYPICAL SOURCES OF STATIC ELECTRIC HAZARDS DURING FUELLING
The following objects can accumulate a static electric charge and cause an ignition spark in typical
fuelling situations:
Ungrounded tanks/containers.
Any ungrounded fuel tank or container can accumulate a static electric charge as a result of
contact with other objects or friction during transportation. This static electricity can discharge
as a spark to the grounded petrol dispenser nozzle as the nozzle is first brought close to the
tank/container at the beginning of the fuelling process.
Flowing petrol.
People are not aware that petrol accumulates static electric charge while flowing through a hose
or pipe. This charge then transfers to and accumulates in the gas tank or container that is being
filled. The total amount of charge accumulation depends on the amount of gas pumped into the
container, the speed with which it is pumped, and whether or not the tank/ container is
grounded. If sufficient static electric charge accumulates in the fuel tank or container during the
fuelling process, the tank/container may discharge a spark to the grounded petrol dispenser
nozzle.
The person dispensing the petrol can carry a static electric charge on their body, typically
resulting from contact with their car seat or electronics. The static electricity can discharge a
spark between that person’s hand and either the grounded dispenser nozzle or the fuel tank
opening.

SAFETY RULES FOR GASOLINE ENGINES
Carbon Monoxide is a product of incomplete combustion, such as exhaust from the engine. Carbon
monoxide is colourless, odourless and tasteless and can kill in a matter of minutes.
Gas particulate filters and respirators will not protect someone from carbon monoxide
poisoning. If symptoms of carbon monoxide poisoning appear, take the affected person
outdoors immediately and away from all structures and equipment that could product gas.
Call for emergency medical treatment and make them aware of the situation.
Operate pressure washer only INDOORS. Do NOT allow exhaust gas fumes from entering confined areas
through windows, open doors, ventilation ducts and other openings.
DO NOT start or run engine indoors or in an enclosed area, such as a garage (even if windows and doors
are open). This also applies to the engine compartment of a recreational vehicle (RV).
The engine exhaust from this product contains chemicals known to Australia to cause cancer, birth
defects or other reproductive harm.
Install a battery powered Carbon Monoxide (CO) detector near all bedrooms to alert occupants of
dangers levels of carbon monoxide.
The emission control system for the engine is warranted for standards set forth by the EPA of Australia.

10
SYMPTOMS OF CARBON MONOXIDE POISONING
Carbon monoxide (CO) is a product of incomplete combustion of fuels and occurs in exhaust fumes of
fuel-burning heaters and all internal combustion engines. It collects in spaces where there is no
constant air flow or ventilation. If you or anyone near you starts to feel sick, dizzy or weak due to
exposure to CO while using the engine, GET FRESH AIR IMMEDIATELY.
ADDING OR DRAINING FUEL TO OR FROM THE ENGINE
Fuel and fuel vapours are extremely flammable and explosive. Fire and
explosions can result in severe burns and even death.
Turn engine to the OFF position and let cool at least two minutes before removing the fuel cap.
Loosen the cap slowly to relieve pressure in the fuel tank.
DO NOT fill or drain fuel tank inside enclosed structures. Accidental sparks can result in fires or
explosions leading to severe burns and even death.
DO NOT overfill fuel tank. Leave ample space for expansion of fuel.
DO NOT start engine in area of fuel spillage. Fire and explosion can occur.
Keep fuel away from sparks, open flames, pilot lights, heat and other ignition sources. DO NOT
smoke while operating the machine.
DO NOT tip engine or equipment at an angle that could result in fuel spilling from fuel tank.
STARTING THE ENGINE
Starter cord kickback (rapid retraction) can pull your hand and arm toward the
engine faster than you can let it go. Failure to be aware of this function can
result in broken bones, fractures and bruises.
When starting the engine, pull the cord slowly until resistance is felt, then pull rapidly to avoid kickback.
Unintentional sparking can result in fire or electric shock. Failure to observe
this warning can result in property damage, severe burns and/or death.
Ensure spark plug is in place before attempting to start engine.
Ensure muffler is secured to engine before starting.
Ensure fuel cap is on fuel tank and tightened securely.
Ensure air cleaner is clean and properly attached to engine.
A dirty air cleaner element changes the air to fuel ration and promotes incomplete
Combustion of fuel increase the output of carbon monoxide. Always make sure
Air cleaner element is clean before every operation of the engine.
DO NOT crank engine with spark plug removed. The resulting spark could ignite spilled fuel.

11
Do not make contact with the muffler area while the engine is running. The muffler gets extremely hot
and can cause severe burns. Exhaust gases can ignite combustible items such as clothing or structures in
close proximity. Gases leaking from a worn muffler can heat up and damage the fuel tank resulting in a

PRESSURE WASHER TERMINOLOGY
Below are common terms associated with the use of pressure washers:
PSI Pounds per square inch –common unit measure used for water pressure, air
pressure, hydraulic pressure and pounds of force.
GPM Gallons per minute (litres per minute (metric) –common unit measures used for
flow rate of water.
Bypass Mode In bypass mode, high pressure pump recirculates water because the spray gun
trigger is not squeezed.
Thermal relief valve When in bypass mode, this valve releases a jet of water to prevent water
temperatures from reaching harmful levels that damage the pump. Once the
water has cooled, the thermal relieve valve will reset itself. DO NOT allow the
pump to run without spraying (in bypass mode) for more than 5 minutes.

SELECTING THE RIGHT NOZZLE FOR THE JOB
The pressure washer comes furnished with five spray nozzles. Each nozzle is colour coded and delivers a
specific spray pattern and pressure for a particular cleaning job. The size of the nozzle determines the
size of the fan spray and the pressure out of the nozzle.
0 Degree Nozzle –RED:
This nozzle delivers as pinpoint stream of pressurised water and is extremely powerful. It covers
only a small area of cleaning. This nozzle should only be directed at surfaces that can withstand
high pressure such as metal or concrete. Do not use this nozzle to clean wood.
15 Degree Nozzle –YELLOW:
This nozzle delivers a power 15 degree spray pattern for intense cleaning of small areas. This
Nozzle should only be used on areas and materials that can withstand high pressure.
25 Degree Nozzle –GREEN:
This nozzle delivers a 25 degree spray pattern for intense cleaning of larger areas. This nozzle
should only be used on areas that can withstand pressure from this nozzle.
40 Degree Nozzle –WHITE:
This nozzle delivers a 40 degree spray pattern and a less powerful stream of water. This
nozzle can cover a wide area and should be used for most general cleaning jobs.
Chemical Nozzle –BLACK:
This nozzle is used to apply special chemicals and cleaning solutions. This nozzle produces the
weakest pressure stream of the five nozzles.
The pressure washer nozzles are stored in receptacles on a panel mounted to the handle
of the washer. Colours on the panel identify nozzle location and spray panel.
NOZZLES TO SPRAY WAND
NEVER place hands in front of the nozzle. Never grasp the hose or fittings during operation. Never
attempt to attach or remove spray wand or hose fittings while the pressure washer system is
pressurised.
TURN OFF the pressure washer and lock the gun trigger before attempting to change pressure nozzles.
To attach, insert the nozzle into the female quick-disconnect spray wand and press
To snap into the nozzle.
To detach, slide down the slip ring on female quick-disconnect to eject the nozzle.
PRESSURE PUMP TO WATER SUPPLY
Connect the garden hose to the water supply and turn water supply on to fill the hose
with water and also remove any debris in the hose. Turn OFF water supply.
Make sure that the filter inside the pressure washer water inlet is clean and
Undamaged. Thread the garden hose fitting into the water hose inlet. Hand tighten the inlet nut.
Turn on water supply.

PREPARING THE PRESSURE WASHER
PRESSURE PUMP
The pressure washer is shipped with shipping oil plug to prevent oil leakage from the pump during
shipping. To replace the shipping plug with the breather plug (provided), perform the following:
Using a wrench, remove shipping plug from pressure pump. Discard shipping plug.
Remove the pump breather plug from the parts bag and insert it into the pressure
pump.
Tighten pump breather plug securely by hand. Do not use a wrench to tighten.
Using a wrench to tighten the pump, could strip the threads.
Use the oil level glass window on the side of the pump to ensure that the pump oil
is at mid-point or above.
Add oil to pressure pump if level is below the prescribed level. Use only 30 weight
Non-detergent oil.
ADDING ENGINE OIL
Move the pressure washer outside and place on a flat and level surface.
Remove the engine oil dip stick and place funnel in the oil reservoir.
Pour the supplied engine oil (30 weight) until oil level reaches the threads
Inside the oil reservoir.
Hand tighten oil dip stick and wipe off any spilled oil.
LOW OIL SENSOR
To prevent engine damage caused by an insufficient amount of oil in the crankcase, the engine is
equipped with a low oil sensor. If the oil is below the safe amount, the sensor will activate and will
prevent engine start-up or will stop the running engine.
If the pressure washer shuts off and the oil level is within specifications, check to see if the pressure
washer is sitting at an angle that forces oil to shift.
Place on an even surface to correct this. If the engine fails to start, the oil level may not be sufficient to
deactivate the low oil level sensor. Add oil as described above.
