BatteryA poorly maintained battery will cor-
rode and discharge quickly. The elec-
trolyte level, battery lead connections
and breather hose routing should be
checked before each ride and at the in-
tervals specified in the periodic main-
tenance and lubrication chart.
To check the electrolyte level
1. Place the scooter on a level surfa-
ce and hold it in an upright posi-
tion.
TIPMake sure that the scooter is posi-
tioned straight up when checking the
electrolyte level.2. Remove panel A. (See page 6-6.)
3. Check the electrolyte level in the
battery.TIPThe electrolyte should be between the
minimum and maximum level marks.4. If the electrolyte is at or below the
minimum level mark, add distilled
water to raise it to the maximum
level mark. NOTICE: Use only

WARNING
EWA10761
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.
5. Check and, if necessary, tighten
the battery lead connections and
correct the breather hose routing.
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.
NOTICE: When removing the
battery, be sure the key is
turned to “ ”, then disconnect
the negative lead before discon-
necting the positive lead.
[ECA17711]
2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte
at least once a month and fully
charge the battery whenever nec-
essary.
3. Fully charge the battery before
installation. NOTICE: When in-
stalling the battery, be sure the
key is turned to “ ”, then con-nect the positive lead before
connecting the negative lead.
[ECA17721]
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals
and that the breather hose is
properly routed, in good condi-
tion, and not obstructed. NOTICE:
If the breather hose is posi-
tioned in such a way that the
frame is exposed to electrolyte
or gas expelled from the bat-
tery, the frame could suffer
structural and external damag-
es.

TroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems your-
self. However, should your scooter re-
quire any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the scooter prop-
erly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
WARNING
EWA15142
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from waterheaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or prop-
erty damage.
