Keep sparks, flames, burning cigarettes, or other ignition sources away at all times. Always wear safety goggles and a face shield when working near batteries.
Maintenance Alternator Belt Alternator Belt The belt tension should be checked after the first 100 hours of operation, when the bat- tery is not charging properly or when the alternator belt is squealing. If the battery contin- ues to not charge properly or the belt continues to squeal after the initial belt adjustment, replace the belt.
