NOTICE
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 system.
Your E-TON engine has been designed to use
regular unleaded gasoline with a pump octane
number [(R+M)/2] of 86 or higher, or a research oc-
tane number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or premi-
um unleaded fuel. Unleaded fuel will give you long-
er spark plug life and reduced maintenance cost.
Gasohol
There are two types of gasohol: gasohol containing
ethanol and that containing methanol. Gasohol
containing methanol and ethanol are not recom-
mended by E-TON because it can cause damage
to the fuel system or ATV performance problems.
WARNING
Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is overfilled,
fuel could spill out due to heat from the en-
gine or the sun.
Be careful not to spill fuel, especially on the
engine or exhaust pipe which can cause a
fire and severe injury. Wipe up any spilled
fuel immediately.
Do not refuel right after the engine has been
running and is still very hot.
Be sure the fuel tank cap is closed securely.
