Battery The battery is located behind panel A.
(See page 6-5 for panel removal and
installation procedures.)
This 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.
EC000101
CAUTION:_ Never attempt to remove the battery
cell seals, as this would permanent-
ly damage the battery. _
EW000116
WARNING
_
Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for
15 minutes and seek prompt
medical attention.
Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.
KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.

6 To charge the battery
Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to
have discharged. Keep in mind that the
battery tends to discharge more quickly
if the motorcycle is equipped with op-
tional electrical accessories.
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 in-
stallation.4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals.
EC000102
CAUTION:_
Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.
To charge a sealed-type (MF)
battery, a special (con-
stant-voltage) battery charger is
required. Using a conventional
battery charger will damage the
battery. If you do not have ac-
cess to a sealed-type (MF) bat-
tery charger, have a Yamaha
dealer charge your battery.
