BATTERY HANDLING

--------------------------------------------------------------------------------------
PREVENTING ELECTRICAL DAMAGE
1. When replacing, jumping, or otherwise connecting the battery
to the battery cables, the proper polarity must be observed.
Failure to observe the proper polarity could result in damage to
the charging circuit. The positive (+) battery cable has a red
terminal cover.
2. If the battery requires charging from an external charger,
disconnect the negative battery cable first and then the positive
battery cable before attaching the charger leads. Failure to do
so can result in damage to the internal charger components.
When reconnecting the cables, connect the positive cable first
and the negative cable last.
PREVENTING BATTERY DISCHARGE
Turn the RUN/STOP switch to stop when engine is not running.
