Checking the brake fluid
level
Front brake
1. Minimum level mark
Rear brake
1. Minimum level mark
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
●When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
●Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
●Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
●Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
●As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the brake master
cylinder and caliper as well as the
brake hose replaced at the intervals
listed below or whenever they are
damaged or leaking.
●Oil seals: Replace every two
years.
●Brake hose: Replace every four
years.
EAU23101
Checking and lubricating the
cables
The operation of all control cables
and the condition of the cables
should be checked before each ride,
and the cables and cable ends should
be lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or repla-
ce it. WARNING! Damage to the
outer sheath may interfere with
proper cable operation and will
cause the inner cable to rust.
Replace a damaged cable as soon
as possible to prevent unsafe con-
ditions.

Checking the front fork
The condition and operation of the
front fork must be checked as follows
at the intervals specified in the perio-
dic maintenance and lubrication
chart.
To check the condition
1. Check the inner tubes for scrat-
ches, damage and excessive oil
leakage.
To check the operation
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion. WARNING! To avoid injury,
securely support the vehicle so
there is no danger of it falling
over.
[EWA10751]
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and
rebounds smoothly.

NOTICE
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or
repair it.

Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
1. Place the vehicle on the centers-
tand. WARNING! To avoid
injury, securely support the
vehicle so there is no danger of
it falling over.
[EWA10751]
2. Hold the lower ends of the front
fork legs and try to move them
forward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the stee-
ring.

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.
