Battery 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

cell seals, as this would permanent-
ly damage the battery. @
EW000116
WARNING
@ l
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.
l
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.
l
KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
@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.
