OPERATION
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 require-
ments. Before using 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 percentages
of oxygenates:
Ethanol (ethyl or grain alcohol) 10% by volume.
You may use gasoline containing up to 10% ethanol
by volume. Gasoline 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 inhibitors 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 resulting from the use of an oxygen-
ated fuel containing more than the percentages
of oxygenates stated previously are not covered
under warranty.
FILLING THE FUEL TANK
See Figure 2.
Clean the surface around the fuel cap to prevent
contamination.
Loosen the fuel cap slowly.
Carefully pour the fuel mixture into the tank.
Avoid spillage.
Prior to replacing the fuel cap, clean and inspect the
gasket.
Immediately replace the fuel cap and hand
tighten. Wipe up any fuel spillage.
NOTE: It is normal for the engine to emit smoke
during and after the first use.
