Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been desig-
ned to use regular unleaded gasoline
with a research octane number of 91
or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.

Catalytic converters
This vehicle is equipped with catalytic
converters in the exhaust system.
EWA10862
The exhaust system is hot after
operation. To prevent a fire hazard
or burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust
system has cooled down befo-
re doing any maintenance
work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
ECA10701
Use only unleaded gasoline. The
use of leaded gasoline will cause
unrepairable damage to the cataly-
tic converter.
