severe acid burns.

Batteries produce explosive
hydrogen gas while being charged.
To prevent a fire or explosion,
charge batteries only in well

flames, and other sources of ignition
away from the battery at all times.
Keep batteries out of the reach of
children. Remove all jewelry when
servicing batteries.

Before disconnecting the negative

switches are OFF. If ON, a spark will
occur at the ground cable terminal
which could cause an explosion if
hydrogen gas or gasoline vapors
are present.
