Check the battery for corroded or loose connections,
cracks, or loose hold±down clamps.
1. If the battery is corroded, wash it off with a solution of
warm water and baking soda. Coat the terminals with grease
to prevent further corrosion.
2. If the connections are loose, tighten the clamp bolts ± but
do not overtighten.

battery firmly in place. Overtightening may damage the
battery case.NOTICE

off before performing maintenance.
When checking the battery, remove the ground cable
first and reinstall it last.

Take care no solution gets into the battery when
washing it.
