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.

Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”) con-
tain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine
performance.
