The battery system can present a risk of electrical shock. These batteries
produce sufficient current to burn wire or tools very rapidly, producing molten
metal. Observe these precautions when replacing the batteries:
1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3. Wear protective eye gear (goggles), rubber gloves and boots.
4. Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or disconnecting the
battery terminals.
6. Determine if the battery is inadvertently grounded. If the battery is, remove
the source of the grounding. Contact with any part of a grounded battery
can result in an electrical shock. The likelihood of such shock will be re-
duced if such grounds are removed during installation and maintenance.
