producing molten metal. Observe these precautions when re- placing 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.

The likelihood of such shock will be reduced, if such grounds are removed during installation and maintenance.
