Checking the wheel bearings
The front and rear wheel bearings
must be checked at the intervals spe-
cified in the periodic maintenance and
lubrication chart. If there is play in the
wheel hub or if the wheel does not
turn smoothly, have a Yamaha dealer
check the wheel bearings.
EAUM1401
Battery
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.
NOTE:
Make sure that the scooter is positio-
ned straight up when checking the
electrolyte level.
2. Remove panel B. (See page 6-6.)

3. Negative battery terminal
1. Maximum level mark
2. Minimum level mark
3. Check the electrolyte level in the
battery.
NOTE:
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.

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.
ECA10610
CAUTION:
Use only distilled water, as tap
water contains minerals that are
harmful to the battery.
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.

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.
ECA10600
CAUTION:
If the breather hose is positioned in
such a way that the frame is expo-
sed to electrolyte or gas expelled
from the battery, the frame could
suffer structural and external
damages.
EAU23630
Replacing the fuses
The main fuse box and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located under
panel B. (See page 6-6.)
If a fuse is blown, replace it as
follows.
1. Turn the key to “
e” and turn off
the electrical circuit in question.
1. Main fuse
2. Radiator fan fuse
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
ECA10640
CAUTION:
Do not use a fuse of a higher ampe-
rage rating than recommended to
avoid causing extensive damage to
the electrical system and possibly a
fire.

WARNING
Keep away open flames and do not smoke while checking or working on the fuel system.
Check the fuel level in
the fuel tank.
1. FuelThere is enough fuel.
There is no fuel.Check the compression.
Supply fuel.
Operate the electric starter.
2. CompressionThere is compression.

Have a Yamaha dealer
check the vehicle.
Remove the spark plugs
and check the electrodes.
3. IgnitionWe t
DryWipe off with a dry cloth and correct the
spark plug gaps, or replace the spark plugs.

3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
4. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap and
spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit sparking
during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark plug
cap.EWA10950
s s
WARNING
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over.
5. 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. Alter-
natively, turn the wheels a little
every month in order to prevent
the tires from becoming degra-
ded 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 pla-
ce [less than 0 °C (30 °F) or more
than 30 °C (90 °F)]. For moreinformation on storing the bat-
tery, see page 6-24.
NOTE:
Make any necessary repairs before
storing the scooter.
