■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the 12-volt battery:
● Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
● Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
● Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near the 12-
volt battery.
