Gasoline and exhaust gas
●GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.
• Never refuel while smoking or
in the vicinity of an open flame.
●Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within
a short time. Always operate your
scooter in an area that has ade-
quate ventilation.
●Always turn the engine off before
leaving the scooter unattended
and remove the key from the
main switch. When parking the
scooter, note the following:
• The engine and exhaust sys-
tem may be hot, therefore,
park the scooter in a place
where pedestrians or children
are not likely to touch these hot
areas.• Do not park the scooter on a
slope or soft ground, otherwise
it may fall over.
• Do not park the scooter near a
flammable source (e.g., a kero-
sene heater, or near an open
flame), otherwise it could catch
fire.
●If you should swallow any gasoli-
ne, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immedia-
tely. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your clot-
hes.
EAU10371
Further safe-riding points
●Be sure to signal clearly when
making turns.
●Braking can be extremely difficult
on a wet road. Avoid hard bra-
king, because the scooter could
slide. Apply the brakes slowly
when stopping on a wet surface.
●Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
●Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
●Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Slow down and
cross them with caution. Keep
the scooter upright, otherwise it
could slide out from under you.
●The brake pads could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

Periodic maintenance and lubrication chart
NOTE:
●The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK,
a mileage-based maintenance, is performed instead.
●From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

EAU22380
Checking the front brake
pads and rear brake shoes
The front brake pads and the rear bra-
ke shoes must be checked for wear at
the intervals specified in the periodic
maintenance and lubrication chart.
EAU22400
Front brake pads
1. Check plug1. Lining thickness
Check each front brake pad for
damage and measure the lining thick-
ness. If a brake pad is damaged or if
the lining thickness is less than
3.1 mm (0.12 in), have a Yamaha dea-
ler replace the brake pads as a set.
EAU22540
Rear brake shoes
1. Wear indicator
2. Wear limit line
The rear brake is provided with a wear
indicator, which allows you to check
the brake shoe wear without having to
disassemble the brake. To check the
brake shoe wear, check the position
of the wear indicator while applying
the brake. If a brake shoe has worn to
the point that the wear indicator rea-
ches the wear limit line, have a Yama-
ha dealer replace the brake shoes as
a set.

EAU32344
Checking the brake fluid
level
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 themaster cylinder is level by turning
the handlebars.
●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 master cylinder when
refilling. Water will significantly
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.
