Battery
ELECTRICAL COMPONENTS: KEY-START WITH
NEUTRAL REV GAS VEHICLE
VIBRATION DAMAGE
The battery hold-down clamp should always be tight enough to keep the battery from bouncing. Battery life may be
severely shortened if the clamp is too loose. Excessive vibration shortens the life of the battery. It may also cause acid
to leak out of the vent caps and corrosion to build up on surrounding metal parts. The acid that is lost reduces the
capacity of the battery and cannot be replaced.
MINERAL CONTENT
For the longest battery life, distilled water should be used in the battery. However, if tap water is going to be used,
contact your local water department to be sure mineral contents are below the levels listed in the following table.
See
following NOTE.
NOTE:
Contact your local water department for mineral content analysis.
