Battery
1. Battery
2. Positive battery terminal
3. Negative battery terminal
A poorly maintained battery will
corrode and discharge quickly. The
electrolyte level, battery lead connec-
tions and breather hose routing
should be checked before each ride
and at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the electrolyte level
1. Place the scooter on a level sur-
face and hold it in an upright
position.
TIP
Make sure that the scooter is positio-
ned straight up when checking the
electrolyte level.
2. Remove panel B. (See page 6-7).
3. Check the electrolyte level in the
battery.
1. Maximum level mark
2. Minimum level mark
TIP
The 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
distilled water, as tap water

WARNING
●Electrolyte 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.
• EXTERNAL: Flush with plenty
of water.
• INTERNAL: Drink large quan-
tities of water or milk and
immediately call a physician.
• EYES: Flush with water for 15
minutes and seek prompt
medical attention.
●Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed spa-
ce.
●KEEP THIS AND ALL BATTE-
RIES 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 tur-
ned to “ ”, then disconnect
the negative lead before dis-
connecting the positive lead.
[ECA16302]
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
necessary.
3. Fully charge the battery before
installation.4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals and that the breather hose is
properly routed, in good condi-
tion, and not obstructed. NOTI-
CE: 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 dama-
ges.

Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter
require any repair, take it to a Yamaha
dealer, whose skilled technicians
have the necessary tools, experience,
and know-how to service the scooter
properly.
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
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoli-
ne or gasoline vapors can ignite or
explode, causing severe injury or
property damage.

WARNING
●Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
●After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the his-
sing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
Wait until the
engine has cooled.Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.
The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.
Add coolant. (See TIP.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
