BatteryThis motorcycle is equipped with a
sealed-type (MF) battery, which does
not require any maintenance. There
is no need to check the electrolyte or
to add distilled water.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 dis-
charge more quickly if the motorcycle
is equipped with optional electrical
accessories.

w8Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.
9EXTERNAL: Flush with plen-
ty of water.
9INTERNAL: Drink large quan-
tities of water or milk and
immediately call a physician.
9EYES: Flush with water for
15 minutes and seek prompt
medical attention.
8Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes,
etc., away from the battery and
provide sufficient ventilation
when charging it in an
enclosed space.8KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
To store the battery
1. If the motorcycle 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 fully
charge it if necessary.
3. Fully charge the battery before
installation.

Replacing the fuses
Fuses, replacing
The main fuse and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located behind
panel A. (See page 6-5 for panel
removal and installation procedures.)
If a fuse is blown, replace it as fol-
lows.
1. Turn the key to “OFF” and turn
off the electrical circuit in ques-
tion.
EC000102
cC8Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.
8To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a
Yamaha dealer charge your
battery.
2. Remove the blown fuse, and
then install a new fuse of the
specified amperage.
