KEEP OUT OF REACH OF CHILDREN.
To remove the battery
1. Remove the seat. (See page 4-10.)
2. Unhook the band securing the owner’s tool kit,
and then remove the battery holding plate by
removing the bolts.
3. Disconnect the negative battery lead first,
then the positive battery lead by removing
their bolt.
4. Pull the battery out of its compartment.
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


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.

If the battery will be stored for more than two
months, check it at least once a month and fully
charge it if necessary.
To install the battery
TIP

Be sure the battery is fully charged.
1. Place the battery in its compartment.
2. Connect the positive battery lead first, then
connect the negative battery lead by installing
their bolt.
3. Install the battery holding plate by installing
the bolts, and then hook the band to secure
the owner’s tool kit.
4. Install the seat. (See page 4-10.)

the next step.)
d. Turn the engine over several times with
the starter. (This will coat the cylinder wall
with oil.)
e. Remove the spark plug cap from the spark
plug, and then install the spark plug and
the spark plug cap.
6. Lubricate all control cables and the pivoting
points of all levers and pedals.
7. Check and, if necessary, correct the tire air
pressure, and then block up the ATV so that
all of its wheels are off the ground. Alternative-
ly, turn the wheels a little every month in order
to prevent the tires from becoming degraded
in one spot.
8. Cover the muffler outlet with a plastic bag to
prevent moisture from entering it.
9. Remove the battery and fully charge it. Store
it in a cool, dry place and charge it once a
month. Do not store the battery in an exces-
sively cold or warm place [less than 0 °C (30
°F) or more than 30 °C (90 °F)]. For more in-
formation on storing the battery, see page
8-36.
TIP

Make any necessary repairs before storing the
ATV.
