PREVENTING CARBON MONOXIDE POSIONING
• Always start and run engine outdoors. Do not start or run engine in an enclosed area,
even if doors or windows are open.
• 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 pointed in the direction away from the operator.
• Never point the exhaust towards anyone. People should always be a minimum of ten feet
away from the operation of the engine and its attachments.
• Do not change the engine governor settings or over-speed the engine.
• Stop the engine (motor) when leaving the operating position.
GASOLINE FIRES AND HANDLING FUEL SAFELY
⚠ Warning gasoline is highly flammable and explosive
You can be burned or seriously injured when handling fuel. Use extreme care when handling
gasoline or other fuels. They are flammable and vapors are explosive.
• When storing extra fuel be sure that it is in an appropriate
container and away from any fire hazards.
• Prevent fire 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 fill fuel tank outside in a well-ventilated area. Never fill
fuel tank with fuel indoors. (Examples include basement, garage,
barn, shed, house, porch, etc.) Never fill tank near appliances
with pilot lights, heaters, or other ignition sources. If the fuel
must be drained, this should be done outdoors. The drained fuel should be stored in a
container specifically 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 filling.
• Do not smoke while using engine or around fuel.
• Never drain fuel from engine in an enclosed area.
