CAUTION! Careful to reduce the risk or dropping a metal tool on the batteries. It could spark
or short circuit the batteries and could cause an explosion.
CAUTION! Remove personal metal items such as rings, bracelets, necklaces, and watches
when working with batteries. Batteries can produce a short circuit current high enough to
make metal melt, and could cause severe burns.
CAUTION! Avoid touching eyes while working near batteries.
CAUTION! Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.
CAUTION! NEVER smoke or allow a spark or flame in vicinity of a battery.
CAUTION! If a remote or automatic generator start system is used, disable the automatic
starting circuit or disconnect the generator to prevent accident during servicing.
