1Terminals 2Hold-down clamp
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.
3. Tighten the hold-down clamp only enough to keep the
battery firmly in place. Overtightening may damage the battery
case.
NOTICE
Make sure the engine and all accessories are turned off before performing maintenance.
When checking the battery, remove the ground cable
first and reinstall it last.
Be careful not to cause a short circuit with tools.
Take care no solution gets into the battery when washing it.
