Fuel
Make sure there is sufficient gasoline in the
tank.
WARNING
Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and ex-
plosions and to reduce the risk of injury
when refueling, follow these instructions.
1. Before refueling, turn off the engine and
be sure that driver and passenger are
outside the vehicle.
Never refuel while smoking, or while in
the vicinity of sparks, open flames, or oth-
er sources of ignition such as the pilot
lights of water heaters and clothes dry-
ers.
2. Do not overfill the fuel tank. Because fuel
expands when it heats up, heat from the
engine or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel immediately.
4. Be sure the fuel tank cap is closed se-
curely.
WARNING
Gasoline is poisonous and can cause inju-
ry or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline or inhale a
lot of gasoline vapor, or get some gasoline
in your eyes, see your doctor immediately.
If gasoline spills on your skin, wash with
soap and water. If gasoline spills on your
clothing, change your clothes.
Your Yamaha engine has been designed to
use regular unleaded gasoline with a pump
octane number ([R+M]/2) of 86 or higher, or
research octane number of 91 or higher. If
knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
Unleaded fuel will give you longer spark plug
life and reduced maintenance cost.
