•
Batteries can present a risk of electrical shock or burn from high short circuit current. The following
precautions should be observed: 1) Remove watches, rings, or other metal objects; 2) Use tools with
insulated handles; 3) Do not lay tools or metal parts on top of batteries; 4) Disconnect charging source prior
to connecting or disconnecting battery terminals; 5) Wear voltage rated gloves and electrical hazard

•
When replacing batteries, replace with the same type and number of batteries or battery packs. Contact
your service representative to order new batteries.
•
Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
•
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
•
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes and
may be extremely toxic.
•
Determine if the battery is inadvertently grounded. If inadvertently grounded, remove source of ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock will
be reduced if such grounds are removed during installation and maintenance (applicable to equipment and
remote battery supplies not having a grounded supply circuit).
•
ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or connectors. Attempting to alter
wiring can cause injury.
