KEEP OUT OF REACH OF CHILDREN.
To charge the battery
Have a Yamaha dealer charge the battery as soon
as possible if it seems to have discharged. Keep in
mind that the battery tends to discharge more
quickly if the ATV is equipped with optional electri-
cal accessories.
To store the battery
1. If 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.
2. If the battery will be stored for more than two
months, check it at least once a month and ful-
ly charge it if necessary.
To install the battery
NOTE:

Be sure the battery is fully charged.
1. Place the battery in its compartment.
2. Make sure to properly connect the battery
leads to the battery terminals.
CAUTION:

ECB00630

Always keep the battery charged. Storing a
discharged battery can cause permanent
battery damage.

To charge a sealed-type (MF) battery, a spe-
cial constant-voltage battery charger is re-
quired. Using a conventional battery charger
will damage the battery. If you do not have
access to a constant-voltage battery charg-
er, have a Yamaha dealer charge your bat-
tery.
