Battery
A poorly maintained battery will corrode and dis-
charge quickly. The electrolyte level, battery lead
connections and breather hose routing should be
checked before each ride and at the intervals
specified in the periodic maintenance and lubrica-
tion chart.
To check the electrolyte level
1. Place the ATV on a level surface.
2. Check the electrolyte level in the battery.
NOTE:

The electrolyte should be between the minimum
and maximum level marks.
3. If the electrolyte is at or below the minimum
level mark, add distilled water to raise it to the
maximum level mark.CAUTION:

ECB00590
Use only distilled water, as tap water contains
minerals that are harmful to the battery.WARNING
EWB02160
Battery electrolyte is poisonous and danger-
ous, as it contains sulfuric acid, which can
cause severe burns. Avoid contact with skin,
eyes or clothing. Always shield your eyes
when working near batteries.
Recommended lubricant:
