Overcharging could cause damage to battery
cells.
Battery wire terminals that are damaged or cor-
roded should be replaced or cleaned as neces-
sary. Failure to do so may cause them to over-
heat during operation.
Danger: Batteries produce explosive hydrogen
gas at all times, especially when being charged.
To avoid personal injury, keep cigarettes, open
flame and sparks away from the battery at all
times. Ventilate area when charging battery.
Raise body or seats over batteries while charg-
ing vehicle to allow hydrogen gas to escape
freely.
Ventilation fans should be located at the highest
point in the room, and must be capable of
changing the total volume of air in the room five
(5) times per hour.
