CAUTION:_ Use only unleaded gasoline. The use of leaded

rings, as well as to the exhaust system. _
WARNING
_

Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine 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 secure-
ly.
