3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10071]
4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15151
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor immedi-ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU41982
For CanadaNOTICE
ECA15590
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the piston rings as well as to
the exhaust system.Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a pump octane number
[(R+M)/2] of 86 or higher, or a research
octane number of 91 or higher. If
knocking (or pinging) occurs, use a
gasoline of a different brand or premi-um unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce
maintenance cost.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if ethanol content
does not exceed 10% (E10). Gasohol
containing methanol is not recom-
mended by Yamaha because it can
cause damage to the fuel system or ve-
hicle performance problems.
