ASSEMBLY
FILLINg TANK
 Clean surface around fuel cap to prevent contamina-
tion.

Loosen fuel cap slowly. Rest the cap on a clean
surface.

Carefully pour fuel into the tank. Avoid spillage.

Prior to replacing the fuel cap, clean and inspect the
gasket.

Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage.
NOTE: It is normal for smoke to be emitted from a new
engine after first use.
WARNINg:
Always shut off engine before fueling. Never add fuel to
a machine with a running or hot engine. Move at least
30 ft. from refueling site before starting the engine. Do
not smoke! Failure to heed this warning could result in
serious personal injury.
OXYgENATED FUELS
Some conventional gasolines are blended with alcohol or an
ether compound. These gasolines are collectively referred
to as oxygenated fuels. To meet clean air standards, some
areas of the United States and Canada use oxygenated fuels
to help reduce emissions.
If using an oxygenated fuel, make sure it is unleaded and
meets the minimum octane rating requirements. Before us-
ing an oxygenated fuel, try to confirm the fuel’s contents.
Some states/provinces require this information to be posted
on the pump. The following are the EPA approved percent-
ages of oxygenates:
Ethanol (ethyl or grain alcohol) 10% by volume. You may
use gasoline containing up to 10% ethanol by volume. Gaso-
line containing ethanol may be marketed under the name
“Gasohol.”
Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (methyl or wood alcohol) 5% by volume. You
may use gasoline containing up to 5% methanol by volume
as long as it also contains cosolvents and corrosion inhibi-
tors to protect the fuel system. Gasoline containing more
than 5% methanol by volume may cause starting and/or
performance problems. It may also damage metal, rubber,
and plastic parts of the product or your fuel system.
If you notice any undesirable operating symptoms, try another
service station or switch to another brand of gasoline.
NOTE: Fuel system damage or performance problems re-
sulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated previously are
not covered under warranty.
