MAINTENANCE AND LUBRICATION
Battery
Your ATV may have either a sealed battery, which requires little
maintenance, or a conventional battery. A sealed battery can be
identified by its flat covers on the top of the battery. A conventional
battery has six filler caps on the top of the battery.
Always keep battery terminals and connections free of corrosion. If
cleaning is necessary, remove corrosion with a stiff wire brush. Wash
with a solution of one tablespoon baking soda and one cup water.
Rinse well with tap water and dry off with clean shop towels. Coat the
terminals with dielectric grease or petroleum jelly. Be careful not to
allow cleaning solution or tap water into a conventional battery.
WARNING
Battery electrolyte is poisonous. It contains sulfuric acid. Serious
burns can result from contact with skin, eyes or clothing.
Antidote:
External: Flush with water.
Internal: Drink large quantities of water or milk. Follow with milk
of magnesia, beaten egg, or vegetable oil. Call physician
immediately.
Eyes: Flush with water for 15 minutes and get prompt medical
attention.
Batteries produce explosive gases. Keep sparks, flame,
cigarettes, etc. away. Ventilate when charging or using in an
enclosed space. Always shield eyes when working near
batteries. KEEP OUT OF REACH OF CHILDREN.
