cause serious injury or death.
•WARNING Gasoline engines produce toxic carbon monoxide exhaust fumes.
INADEQUATE VENTILATION
•Materials placed against or near the pressure washer or operating in areas where the temperature
exceeds 40°C ambient (such as storage rooms or garages) can interfere with its proper ventilation
features causing overheating and possible ignition of the materials or buildings.
•Operate pressure washer in a clean, dry, well-ventilated area a minimum of 4’ (1.2 m) from any
building, object or wall. DO NOT OPERATE UNIT INDOORS OR IN ANY CONFINED AREA.
FUEL IS HIGHLY FLAMMABLE AND POISONOUS
•Always turn off the engine when refuelling.
•Never refuel while smoking or in the vicinity of an open flame.
•When operating or manoeuvring this pressure washer, be sure to keep it upright. If it tilts, fuel may
leak from the carburettor or fuel tank.
DO NOT ATTEMPT TO FILL GASOLINE TANK WHILE ENGINE IS RUNNING.
•Gasoline and gasoline vapours can become ignited by coming into contact with hot components
such as the muffler, engine exhaust gases, or from an electrical spark.
•Turn engine off and allow it to cool before adding fuel to the tank. Equip the area of operation with a

fire extinguisher certified to handle gasoline or fuel fires.
SPARKS, FIRE, HOT OBJECTS
•Cigarettes, sparks, fires, or other hot objects can cause gasoline or gasoline vapours to ignite.
ENGINE AND MUFFLER MAY BE HOT
•Place the pressure washer in an appropriate location, away from children and pedestrians.
•Avoid placing any flammable materials near the exhaust outlet during operation or shortly thereafter.
•Keep a 4’ (1.2 m) clearance from buildings or other equipment around the pressure washer to
prevent overheating.
•WARNING The engine muffler will be very hot during and after use, avoid touching the
engine or muffler while they are still hot.
HOT MUFFLER & HIGH PRESSURE HOSE
•Muffler will become very hot during operation. DO NOT TOUCH MUFFLER WHILE IN USE OR
SHORTLY THEREAFTER.
•Keep hose away from the hot muffler or it may damage the hose. Do not use a damaged high
pressure hose. Do not kink the high pressure hose.
APPLICATION

application other than which it is designed. This equipment is not designed for industrial use. Please
refer to icons above for suggested uses.
NEVER OPERATE UNDER THE FOLLOWING CONDITIONS
•When a noticeable change in engine speed occurs.
•Engine misfires.
•Loss of water pressure.
•Smoke or flames in the area.
•Excessive vibration.
WATER SPRAY
•Never direct the water spray towards ANY person, animal, electrical wiring or the pressure washer
itself.
•DO NOT spray too close to the surface or damage could occur.
•The vendor is not responsible for damage caused by improper use.

PREVENT ACCIDENTAL WATER SPRAY
•To prevent accidental water spray, the wand trigger should be placed in the locked position when
not in use.
KEEP HANDS AWAY
•Keep hands and other body parts away from high pressure water stream as water pressure will
cause severe bodily harm.
SAFETY GLASSES

WARRANTY.
SAFETY FEATURES
•Thermal Relief Valve
Protects the pump from overheating in case nozzle becomes clogged. This system should not be
abused. Make every effort to prevent the pump from overheating.
•Low-Oil Auto Shut-Off
This pressure washer is equipped with a low oil shut-off system. If the engine oil level goes below
the recommended oil level, the pressure washer will automatically shut-off. This protects your
engine and prevents operating without proper lubrication.

stored or placed near the pressure washer.
•When storing pressure washer for winter, ensure that the pressure washer is stored indoors (at
room temperature) in a dry location away from any heat sources.
•If unused gas will not be used for alternative purposes immediately, ensure you use fuel stabilizer to
keep the gas from breaking down.
•To protect and extend the life of your pressure washer when storing, use pump antifreeze which can
be found at your local Canadian Tire store.
PREVENT PUMP DAMAGE

WARNING! Before attempting to start
pressure washer, ensure you complete the
following important steps.
1) Fill gasoline tank with Unleaded Gasoline. This
is a 4-cycle engine with separate reservoirs for
gas and oil. DO NOT use pre-mixed gas! DO
NOT use old gas! Fuel must be purchased
separately.
2) Fill oil tank with SAE 10W-30 oil. Running
pressure washer without oil will severely
damage engine which is not covered by
warranty! Oil must be purchased separately.

1) Turn the oil gauge dipstick(A)
counter clockwise; remove it and clean it with a
clean cloth.
2) Fully reinsert the oil gauge dipstick and pull it
out to check the oil level.
3) If the oil level is halfway up the dipstick or
below, refill with SAE 10W-30 oil through the
dipstick hole until the oil level reaches 3/4 up
the dipstick or until it reaches the bottom lip of
the dipstick hole as shown in illustration to the
right.
4) Re-position the oil gauge dipstick and tighten it
by turning clockwise.
PRE-START CHECK FUEL LEVEL
WARNING! Make sure there is enough fuel in the fuel tank before operating.
1) If it is necessary to add fuel, first make sure
