• CAUTION: A battery can present a risk of electrical shock and high short-
circuit current. The following precautions should be observed when working
on batteries:
– Disconnect the charging source prior to connecting or disconnecting
battery terminals.
– Do not wear any metal objects including watches and rings.
– Do not lay tools or metal parts on top of batteries.
– Use tools with insulated handles.
– Wear rubber gloves and boots.
– Determine if battery is either intentionally or inadvertently grounded.
Contact with any part of a grounded battery can result in electric shock
and burns by high short-circuit current. The risk of such hazards can be
reduced if grounds are removed during installation and maintenance
by a skilled person.
