Always wear eye protection when checking the bat- tery, acid can cause serious injury to skin and eyes. If contact occurs, flush area with clean water and call physician immediately. Acid will also damage cloth- ing.

Do not drink the battery electrolyte.

Do not allow open flame near the battery when charg- ing.

Hydrogen gas forms inside the battery. This gas is both toxic and flammable and may cause an explosion if exposed to flame. Always remove the negative ground first and replace it last.

Do not overfill battery.

Electrolyte may overflow and damage paint, wiring or structure. When cleaning the battery, use soap and water. Be careful not to get soap and water into the battery. Clean the battery terminals with a solution of four parts water and one part baking soda when they become corroded.

WARNING: Shorts caused by battery terminals or metal tools touching metal tractor components can cause sparks. Sparks can cause a battery gas explo- sion which will result in personal injury.

Prevent the battery terminals from touching any metal tractor parts when removing or installing the battery. Do not allow metal tools to short between the battery terminals and metal tractor parts.

WARNING: Incorrect battery cable routing could cause damage to the tractor and battery cables. This can cause sparks which can cause a battery gas explo- sion which will result in personal injury.

Always disconnect the negative (black) battery cable(s) before disconnecting the positive (red) cable(s).

Always connect the positive (red) battery cable(s) before connecting the negative (black) cable(s).

Use SAE multi-purpose grease.
