ENGINE SAFETY PRECAUTIONS
Preventing Carbon Monoxide Poisoning
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may be
pulled into a building.
• Never run engine outdoors in a poorly ventilated area
where the exhaust fumes may be trapped and not easily
taken away. (Examples include: in a large hole or areas
where hills surround your working area.)
• Never run engine in an enclosed or partially enclosed area.
(Examples include: buildings that are enclosed on one or
more sides, under tents, car ports or basements.)
• Always run the engine with the exhaust and muer
pointed in the direction away from the operator.
• Never point the exhaust muer towards anyone. People
should always be many feet away from the operation of
the engine and its attachments.
• Do not change the engine governor settings or overspeed the engine.
• Stay away from rotating parts. Place protective covers over
rotating parts.
• Do not use engine around dry brush, cloth rags, or other
ammable materials.
• Always keep materials and debris clear of muer guard
and other hot engine parts.
• Never operate the engine without the muer guard in
place.
• Always make sure the exhaust pipe is free of foreign
objects.
• The engine exhaust becomes very hot during operation.
Keep engine at least three feet away from buildings and
other equipment during operation.
• Wear appropriate clothing such as a long-sleeved shirt
or jacket. Also wear long trousers or slacks. Do not wear
shorts. Never wear sandals, sneakers, or open shoes, and
never operate the machine with bare feet.
• Do not wear loose clothing or jewelry. They can get caught

Gasoline Fires and Handling Fuel Safely
Use extra care in handling gasoline and other fuels. They are
ammable and vapors are explosive.
• When storing extra fuel be sure that it is in an appropriate
container and away from any re hazards. Prevent re
and explosion caused by static electric discharge. Use
only nonmetal, portable fuel containers approved by the
Underwriter’s Laboratory (U.L.) or the American Society for
Testing & Materials (ASTM).
• Always ll fuel tank outside in a well ventilated area. Never
ll your fuel tank with fuel indoors. (Examples include:
basement, garage, barn, shed, house, porch, etc.) Never
ll tank near appliances with pilot lights, heaters, or other
ignition sources. If the fuel has to be drained, this should
be done outdoors and with the proper equipment. Do not
pour fuel from fuel tank. The drained fuel should be stored
in a container specically designed for fuel storage or it
should be disposed of carefully.
• Never remove the fuel cap or add fuel with the engine
running. Stop engine and allow to cool before removing
the fuel cap/and or relling the engine.
• Do not smoke near or while handling engine fuel.
• Never drain fuel from engine in an enclosed area.
• During storage, tightly screw down fuel cap.
• Never pour fuel from engine fuel tank.
• Never siphon fuel by mouth to drain fuel tank.
• Always have an adult ll the fuel tank and never allow
children to ll the engine.
• Never allow an adult or anyone under the inuence of
drugs or alcohol to ll engine.
• When storing gasoline or equipment with fuel in the tank,
store away from furnaces, stoves, water heaters or other
appliances that have a pilot light or other ignition source
because they can ignite gasoline vapors.
Burns and Fires
• The muer, muer guard and other parts of the engine
become extremely hot during the operation of the engine.
These parts remain extremely hot after the engine has
stopped.
Prevention of Burns and Fires
• Never remove the muer guard from the engine.
• Never touch the muer guard because it is extremely hot
and will cause severe burns.
• Never touch parts of the engine that become hot after
operation.
• Always keep materials and debris away from muer guard
and other hot parts of the engine to avoid res.
SERVICE
• Always stop the engine whenever you leave the
equipment, before cleaning, repairing or inspecting the
unit. Engine should be turned o and cool, spark plug
wire must be removed from spark plug before any repairs
or adjustments are attempted. Never make adjustments or
repairs with the engine (motor) running. Disconnect the
spark plug wire, and keep the wire away from the plug to
prevent accidental starting.
• Always wear eye protection when you make adjustments
or repairs.
• Keep all nuts and bolts tight and keep equipment in good
condition. Never tamper with safety devices. Check their
proper operation regularly.
• When servicing or repairing the engine, do not tip the
engine over or up unless specically instructed to do so in
this manual. Service and repair procedures can be done
with the engine in an upright position. Some procedures
will be easier if the engine is lifted on a raised platform or
working surface.
• To reduce re hazard, keep engine free of grass, leaves, or
other debris build-up. Clean up oil or fuel spillage. Allow
engine to cool before storing.
• Stop and inspect the equipment if you strike an object.
Repair, if necessary, before restarting.
• Clean and replace safety and instruction decals as
necessary.
• To guard against engine over-heating, always have engine
