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.

Replacing the fuse
The fuse holder is located beside the battery and
can be accessed as follows:
1. Remove the seat. (See page 4-10.)
2. Unhook the band, and then take out the own-
er’s tool kit and the low-pressure tire gauge.
3. Remove the battery cover by removing the
battery cover bracket bolts.

circuits.CAUTION:
ECB00640
To prevent accidental short-circuiting, turn off
the main switch when checking or replacing a
fuse.
2. Remove the blown fuse, and then install a
new fuse of the specified amperage.

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.
NOTE:

Make any necessary repairs before storing the
ATV.
