shield and rubber gloves when working on or near batteries.
5. Carefully check the electrolyte level and add distilled water if necessary. Do not fill the battery cells above
the designated fill line. Replace battery cell caps.
6. Clean both battery terminals with a solution of baking soda and water (1 cup (237 mL) baking soda per
1 gallon (3.8 L) of water). Rinse thoroughly. Do not allow this solution to enter the battery. Tighten battery
terminals to 144 in-lb (16 N·m). Let the terminals dry and then spray them with Battery Terminal Protector

WARNING
• If battery wire terminals are damaged or corroded, replace or clean them as necessary. Failure
to do so may cause them to overheat during operation and could result in a fire, property
damage, or personal injury.
Be sure the battery hold-down clight is properly tightened. Tighten to 9 ft-lb (12.2 N·m). A loose clight may
allow the battery to become damaged from vibration or jarring.
If battery appears weak, have it charged by a trained technician. The battery should never be left discharged
any longer than absolutely necessary (do not leave discharged overnight).
