ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide.
Carbon monoxide is a deadly, colorless, tasteless,
odorless gas which may be present even if you do
not smell or see engine exhaust. Levels of carbon
monoxide, which can be deadly, can be present for
days in an enclosed area that has poor ventilation.
Any level of carbon monoxide, if inhaled, can cause
headaches, drowsiness, nausea, dizziness, confusion
and eventually death. If you experience any of these
symptoms, seek fresh air and medical attention
immediately.
Preventing Carbon Monoxide Poisoning
• Never run engine indoors or in a conned area.
• 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 removed. (Examples include large holes
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 away from the operator.
• Never point the exhaust muer towards anyone.
Bystanders should always be many feet away from
the operation of the engine.
Gasoline Fires and Handling Fuel Safely
Fuel and fuel vapors are highly ammable. Never use
fuel where a spark or ame may be present. Never use
fuel where a potential source of ignition could occur.
(Examples include: hot water or space heaters, clothes
dryer, electric motors, etc.) Keep ames and sparks
away from engine and fuel to prevent res. Fuel res
spread very quickly and are highly explosive.
Prevention of Gasoline Fires
• Always ll fuel tank outside in a well ventilated area
with the engine stopped.
• Never remove the fuel cap or add fuel with the
engine running. Stop engine and allow to cool
before lling.
• Never drain fuel from engine in an enclosed area.
• Always wipe up excess (spilled) fuel from engine
before starting. Clean up spilled fuel immediately.
• If fuel spillage occurs, wipe away carefully and allow
fuel to dry before starting the engine.
• Allow fuel fumes/vapors to escape from the area
before starting engine.
• Test the fuel cap for proper installation before
starting and using engine.
• Always run the engine with fuel cap properly
installed on the engine.
• Never smoke while relling engine fuel tank.
• 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).
• Do not store engine with fuel in fuel tank indoors.
Fuel and fuel vapors are highly explosive.
• During storage, screw down gas cap vent screw
tightly.
• Never pour fuel from engine fuel tank.
• Never siphon fuel by mouth to drain fuel tank.
• Always have an adult ll the fuel tank.
• Never allow anyone under the inuence of drugs or
alcohol to ll engine.
• Never allow children to ll the fuel tank.
