CAUTION:l
Do not use accessories requiring more
than the above maximum capacity. This
may overload the circuit and cause the
fuse to blow.
l
If accessories are used without the engine
running or with the headlight turned on,
the battery will lose its charge and engine
starting may become difficult.
l
Do not use an automotive cigarette light-
er or other accessories with a plug that
gets hot because the jack can be dam-aged.

WARNING

l
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.
l
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.
l
Do not refuel right after the engine has
been running and is still very hot.
