Rear brake pads
Each rear brake pad is provided with
a wear indicator groove, which allows
you to check the brake pad wear
without having to disassemble the
brake. To check the brake pad wear,
check the wear indicator groove. If a
brake pad has worn to the point that
the wear indicator groove has almost
disappeared, have a Yamaha dealer
replace the brake pads as a set.

Observe these precautions:
8When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.

Checking the brake fluid
level
Brake fluid level, checkingInsufficient 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
brake 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 leak-
age.

6 8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water or dust
does not enter the brake fluid
reservoir when refilling. Water
will significantly lower the boiling
point of the fluid and may result
in vapor lock, and dirt may clog
the ABS hydraulic unit valves.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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.
EAU02962
Checking and lubricating the
cables
Cables, checking and lubricatingThe 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 replace it.

Damage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.
EAU03976
Changing the brake fluidBrake fluid, changingHave a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the master
cylinders and calipers as well as the
brake hoses replaced at the intervals
listed below or whenever they are
damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years.Recommended lubricant:
Engine oil

To check the operation
1. Place the scooter on a level sur-
face and hold it in an upright
position.
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.

Checking the steeringSteering, checkingWorn 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.

must be checked at the intervals
specified 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.
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 steering.

BatteryBatteryThis scooter is equipped with a
sealed-type (MF) battery, which does
not require any maintenance. There
is no need to check the electrolyte or
to add distilled water.
To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it
seems to have discharged. Keep in
mind that the battery tends to dis-
charge more quickly if the scooter is
equipped with optional electrical
accessories.

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.
9 9
EXTERNAL: Flush with
plenty of water.
9 9
INTERNAL: Drink large
quantities of water or milk
and immediately call a
physician.
9 9
EYES: Flush with water for
15 minutes and seek prompt
medical attention.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. 8 8
Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes,
etc., away from the battery and
provide sufficient ventilation
when charging it in an
enclosed space.

Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.

To 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.
1. Turn the key to “OFF” and turn
off all electrical circuits.
2. Remove the blown fuse, and
then install a new fuse of the
specified amperage.
EC000103
cC
Do 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.
