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.
8EXTERNAL: Flush with
plenty of water.
8INTERNAL: Drink large
quantities of water or milk
and immediately call a
physician.
8EYES: 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 en-
closed space.To store the battery
1.If the scooter 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.
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.
8KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.

2.Remove the blown fuse, and
then install a new fuse of the
specified amperage.
EC000103
cCDo not use a fuse of a higher
amperage rating than recommend-
ed to avoid causing extensive
damage to the electrical system
and possibly a fire.3.Turn the key to ÒONÓ and turn on
the electrical circuit in question to
check if the device operates.

95.Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
6.Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
7.Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.8.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 excessively cold or warm
place (less than 0 ¡C or more
than 30 ¡C). For more informa-
tion on storing the battery, see
page 6-32.
NOTE:
Make any necessary repairs before
storing the scooter.
