EBU25229Battery This model is equipped with a VRLA (Valve Regu-
lated Lead Acid) battery. There is no need to check
the electrolyte or to add distilled water. However,
the battery lead connections need to be checked
and, if necessary, tightened.NOTICEECB00620Never attempt to remove the battery cell seals,as this would permanently damage the battery.
WARNING

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.

INTERNAL: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten egg
or vegetable oil. Call a physician immediately.
EYES: Flush with water for 15 minutes and get

battery, a special (constant-voltage) battery
charger is required. Using a conventional bat-
tery charger will damage the battery. If you do
not have access to a constant-voltage battery
charger, have a Yamaha dealer charge yourbattery.
To store the batteryIf the ATV will not be used for more than one
month, remove the battery, fully charge it, and
then place it in a cool, dry place.If the battery will be stored for more than two
months, check it at least once a month and fully
charge it if necessary.NOTICEECB00940Always keep the battery charged. Storing a dis-
charged battery can cause permanent batterydamage.
