Fuel Safety
DANGER
Gasoline is extremely flammable and vapors are
explosive.
A fire or explosion from gasoline can burn you,
others, and cause property damage.
• Fill the fuel tank outdoors on level ground,
in an open area, when the engine is cold. If
fuel is spilled, Do Not attempt to start the
engine. Move away from the area of the spill
and avoid creating any source of ignition until
fuel vapors have dissipated.
• Do Not refill the fuel tank or drain the
machine indoors or inside an enclosed trailer.
• Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by spark.
• Add fuel before starting the engine. Never
remove the cap of the fuel tank or add fuel
when engine is running or when the engine
is hot.
• Store gasoline in an approved container and
keep it out of the reach of children.
• Do Not operate without entire exhaust system
in place and in proper working condition.
• In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite gasoline vapors.
– Do Not fill containers inside a vehicle or on a
truck or trailer bed with a plastic liner. Always
place containers on the ground and away from
your vehicle before filling.
– When practical, remove gas-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on the
ground. If this is not possible, then refuel
such equipment on a truck or trailer from a
portable container, rather than from a gasoline
dispenser nozzle.
– If a gasoline dispenser nozzle is used, keep the
nozzle in contact with the rim of the fuel tank
or container opening at all times until fueling
is complete. Do Not use a nozzle lock open
device.
• Do Not overfill the fuel tank. Fill the fuel tank to
the bottom of the filler neck. The empty space in
the tank allows gasoline to expand. Overfilling
may result in fuel leakage or damage to the engine
or emission system.
• Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors may cause serious
injury and illness.
– Avoid prolonged breathing of vapors.
– Keep face away from nozzle and gas
tank/container opening.
– Keep away from eyes and skin.
• To help prevent fires:
– Keep engine and engine area free from
accumulation of grass, leaves, excessive grease
or oil, and other debris which can accumulate
in these areas.
– Clean up oil and fuel spills and remove fuel
soaked debris.
– Allow the machine to cool before storing the
machine in any enclosure. Do Not store the
machine or fuel container, or refuel, where
there is an open flame, spark, or pilot light
such as on a water heater or other appliance.
Filling the Fuel Tank
Use a fuel stabilizer/conditioner in the machine to
provide the following benefits:
• Keeps gasoline fresh during storage of 30 days or
less. For longer storage it is recommended that
the fuel tank be drained.
• Cleans the engine while it runs.
• Eliminates gum-like varnish buildup in the fuel
system, which causes hard starting Add the
correct amount of gas stabilizer/conditioner to
the gas.
Note: A fuel stabilizer/conditioner is most
effective when mixed with fresh gasoline. To
minimize the chance of varnish deposits in the
fuel system, use fuel stabilizer at all times.
Make sure the engine is shut off and the parking
brake is engaged. Tank maximum capacity is 3 gallons
(11 L).
Note: Use the fuel window to verify the presence of
gasoline before filling the tank.
Important: Do Not overfill fuel tank. Fill the
fuel tank to the bottom of the filler neck. The
