Refer to the Maintenance section of this manual.
Ensure petrol and oil are well mixed before lling the fuel tank.

Incorrect Fuel mix can damage the engine -
Too much oil will cause excessive smoking.
Too little will cause the moving parts to wear rapidly
& cause the engine to seize and may be irreparable.
Modern fuels are unleaded & will not harm the engine.
Use low octane Fuel. Petrol must be stored in a fuel-safe container.
Modern fuels may fail if stored for longer than 4 to 6 months.

PRECAUTIONS:
Always operate petrol powered engines outside in a well ventilated area.
Exhaust fumes contain carbon monoxide an odourless and deadly gas,
amongst other toxic chemicals. Small children and pregnant women are at
great risk from these gases.
Exhaust fumes are Dangerous to ALL Humans and other creatures.
Do NOT touch the mufer or engine body while operating or until
the stopped motor has cooled, the engine operates at temperatures
that can cause serious burns.
Do NOT touch the ignition system or Spark Plug while the machine
is operating. The ignition system generates a high voltage charge
that can cause a painful shock.
Do NOT smoke or permit naked fames anywhere near the engine, or
near fuel containers. Resulting explosion can cause Death.
NEVER mix or store petrol/oil mixture indoors or in enclosed, poorly
ventilated areas, where fuel fumes may reach an open ame, spark
or pilot light as on a furnace, water heater, clothes dryer or other
gas appliance.
GOLDEN RULES FOR ‘TROUBLE FREE’ OPERATION
START UP
1. Turn on the fuel tap and allow the carburettor to ll.
2. Close the choke on the carburettor completely (for cold starts) by moving
the throttle control fully forward (refer mower owner manual).
3. Pull the starter cord until the engine starts, then open the choke and
allow the engine to warm up at low revs for 3-5 minutes.
4. When the engine is heated enough, adjust the throttle handle to the
required speed.
NOTE: High revs at start up will damage the engine as lubrication is less
effective in a cold engine.
This motor will run at moderate to full speed without problems, providing the
factory approved settings have not been altered.
NEVER run engine indoors or in enclosed, poorly ventilated areas.
Engine exhaust contains carbon monoxide, an odorless and deadly
gas.
Keep hands, feet, hair and loose clothing away from any moving
parts on the engine.
WARNING - Temperature of mufer and nearby areas may exceed
65ºC avoid these areas.
STOPPING
1. Reduce the engine speed to the lowest setting for 3-5 minutes.
2. Stop the engine with either the throttle control or by turning off the fuel.
Note: do not wash the engine down while it is still hot, this can cause
damage to the block and seals.
REFUELLING
Always stop the engine before refuelling, and allow the engine to cool.
Petrol fumes are highly inammable so remove the fuel cap carefully to
release pressure gently, ensure the engine is re-fuelled from a petroleum-
safe container and that refuelling takes place outdoors in a well ventilated
area to avoid fumes build-up.
DO NOT start or run the engine if the fuel tank has been over-lled or
spillage has occurred.
Ensure excess fuel is completely removed, areas cleaned and washed
before attempting to start or run the engine.
NEVER ll the tank indoors, NEVER ll fuel tank when engine is
running or hot.
DO NOT smoke when lling fuel tank.
NEVER ll fuel tank completely. Fill tank to 1/2” below bottom of ller
neck to provide space for fuel expansion.
Wipe any fuel spillage from engine and equipment before starting
the engine.
REMEMBER: INCORRECT FUEL RATIO = ENGINE FAILURE
MAINTENANCE
Check at each operation;
• Check all screws and nuts are tight
• Check for fuel leaks.
• All fuel leaks must be repaired immediately
DO NOT use the engine.
Check after running 20 hours;
• Clean the air lter – rinse in petrol, wring dry and add 5ml of clean
engine oil to the lter, squeeze lter to spread oil before re-tting
(ensure petrol has evaporated before re-tting)
• Clean the fuel strainer
Check after running 50 hours;
(will likely require Mechanic to undertake)
• Check the cylinder head nuts for tightness. Tighten to 8-10N.m.
• Clean the accumulated carbon off both the head and exhaust port
(see below).
• Clean the spark plug, and adjust the clearance to 0.6mm.
• Clean the mufer of excess carbon
0.6mm
Clean the accumulated carbon off
both the head and exhaust port.
Never store engine with fuel in tank indoors or in enclosed, poorly
ventilated areas, where fuel ames may reach an open ame, spark
or pilot light as on a furnace, water heater, clothes dryer or other gas
appliances.
DO NOT MAKE ANY UNNECESSARY ADJUSTMENTS. FACTORY SETTINGS
ARE SATISFACTORY FOR MOST CONDITIONS.
CARBURETOR
If you think your carburetor needs adjusting, see your nearest
AUTHORISED MASPORT SERVICE OUTLET. Engine performance
should not be affected at altitudes up to 7,000 feet. For operation at
higher elevations, contact your AUTHORISED MASPORT SERVICE OUTLET.
ENGINE SPEED:
NEVER TAMPER WITH ENGINE GOVERNOR WHICH IS FACTORY SET FOR
PROPER ENGINE SPEED. OVERSPEEDING ENGINE ABOVE FACTORY HIGH
SPEED SETTING CAN BE DANGEROUS. CHANGING OF ENGINE GOVERNED
SPEED WILL VOID ENGINE WARRANTY.
STORAGE
If the engine is to be stored for any extended period (over 30 days);
• Remove all fuel from the tank
• Close the choke fully on the carburettor
• Remove the spark plug and insert 10ml of engine oil through the
spark plug hole.
• Turn the engine over 3-4 times with the starter cord, leaving the
piston at the top of the stroke, reinsert the spark plug.
(Some smoking will occur on rst start-up after storage but this should not
effect engine components & should cease after a short period)
Store engine in a dry, well ventilated area.
The engine will not shut down:
Turn off the fuel – and let the engine stop by running out of fuel.
The ignition switch is not earthed:
Test the circuit or take to your service agent
The engine stops suddenly:
Check to see if the fuel tank is empty.
Check the fuel is owing, if not, clean the fuel lter.
Ensure the breather hole in the fuel cap is not clogged.
Check that water, dirt or gum hasn’t contaminated the fuel.
(In certain conditions condensation can occur inside the fuel tank causing droplets of
water that can accumulate at the bottom of the Fuel Tank.)
Check the spark plug lead is undamaged and in place on the plug.
Check the spark plug isn’t oiled or carboned up, check spark by removing
the plug from the engine, reattach the lead and, while resting the spark
plug thread against the engine body, turn over the engine by pulling on
the starter cord. If a spark isn’t seen, try a new plug. If this fails see your
service agent.
(NOTE: DO NOT hold the plug in the hand as the high voltage will cause a painful electrical shock.)
The engine is hard to start:
Weak spark, faulty Spark plug or Spark plug lead Choke has not been set
correctly – must be closed on initial start-up.
Using old fuel that has been stored too long, or poor quality fuel.
Blade impact on a solid object may have bent the crank shaft or snapped
the Woodruff Key.
