vicinity of sparks, open fl ames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfi ll the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank fi ll-
er hole. Stop fi lling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine
or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel im-
mediately.
NOTICE:
Immedi-
ately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel
may deteriorate painted sur-
faces or plastic parts.[ECA10071]
4. Be sure to securely close the fuel
tank cap.
EWA15151
WARNING
Gasoline is poisonous and can
cause injury or death. Handle
gasoline with care. Never siphon
gasoline by mouth. If you should
swallow some gasoline or inhale a
lot of gasoline vapor, or get some
gasoline in your eyes, see your
doctor immediately. If gasoline
spills on your skin, wash with soap
and water. If gasoline spills on your
clothing, change your clothes.
EAU33520
Recommended fuel:
REGULAR UNLEADED GASO-
LINE ONLY
Fuel tank capacity:
7.4 L (1.96 US gal) (1.63 Imp.gal)
ECA11400
NOTICEUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use of unleaded fuel will extend spark plug
life and reduce maintenance costs.

Catalytic convertersThis vehicle is equipped with catalytic
converters in the exhaust system.
EWA10862
WARNING
The exhaust system is hot after op-
eration. To prevent a re hazard or
burns:● Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.● Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.● Make sure that the exhaust
system has cooled down be-
fore doing any maintenance
work.● Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
ECA10701
NOTICEUse only unleaded gasoline. The
use of leaded gasoline will cause
unrepairable damage to the cata-
lytic converter.

1. Kickstarter To start the engine, fold out the kick-
starter lever, move it down lightly with
your foot until the gears engage, and
then push it down smoothly but force-
fully.

Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the in-
spection and maintenance procedures and schedules described in the Owner’s Manual.
EWA11151
WARNING
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment dam-
age. Do not operate the vehicle if you nd any problem. If a problem cannot be corrected by the procedures pro-
vided in this manual, have the vehicle inspected by a Yamaha dealer.

PERIODIC MAINTENANCE AND ADJUSTMENT
EAUS1823
Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most effi cient condition
possible. Safety is an obligation of
the vehicle owner/operator. The most
important points of vehicle inspection,
adjustment, and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However,
depending on the weather, terrain,
geographical location, and individual
use, the maintenance intervals may
need to be shortened.
EWA10321
WARNING
Failure to properly maintain the
vehicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle.
If you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EWA15122
WARNING
Turn off the engine when perform-
ing maintenance unless otherwise
speci ed.● A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
res.● Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monox-
ide poisoning - possibly lead-
ing to death. See page 1-2 for
more information about carbon
monoxide.
EWA10330
WARNING
This scooter is designed for use
on paved roads only. If this scooter
is operated in abnormally dusty,
muddy or wet conditions, the air
lter element should be cleaned or
replaced more frequently, other-
wise rapid engine wear may result.
Consult a Yamaha dealer for proper
maintenance intervals.
EWA15460
WARNING
Brake discs, calipers, drums, and
linings can become very hot dur-
ing use. To avoid possible burns,
let brake components cool before
touching them.
EAU17302
Emission controls not only function
to ensure cleaner air, but are also
vital to proper engine operation and
maximum performance. In the follow-
ing periodic maintenance charts, the
services related to emissions control
are grouped separately. These serv-
ices require specialized data, knowl-
edge, and equipment. Maintenance,
replacement, or repair of the emission
control devices and systems may be
performed by any repair establishment
or individual that is certifi ed (if applica-
ble). Yamaha dealers are trained and
equipped to perform these particular
services.

correctly.TIPIf you do not have the tools or expe-
rience required for a particular job,
have a Yamaha dealer perform it for
you.

TIP● 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.

TIP● Air fi lter and V-belt fi lter
• This model’s air fi lter is equipped with a disposable oil-coated paper element, which must not be cleaned with
compressed air to avoid damaging it.
• The air fi lter element needs to be replaced and V-belt fi lter needs to be serviced more frequently when riding in
unusually wet or dusty areas.● Hydraulic brake service
• After disassembling the brake master cylinder and caliper, always change the fl uid. Regularly check the brake
fl uid level and fi ll the reservoir as required.
• Every two years replace the internal components of the brake master cylinder and caliper, and change the brake
fl uid.
• Replace the brake hose every four years and if cracked or damaged.
