SAFETY INFORMATION
EAUT1019
Be a Responsible Owner
As the vehicle’s owner, you are re-
sponsible for the safe and proper oper-
ation of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements be-
fore riding this scooter.
He or she should:
Obtain thorough instructions from
a competent source on all aspects
of scooter operation.
Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.
Obtain qualified training in safe
and proper riding techniques.
Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions.Never operate a scooter without
proper training or instruction. Take
a training course. Beginners
should receive training from a cer-
tified instructor. Contact an autho-
rized scooter dealer to find out
about the training courses nearest
you.
Safe Riding
Perform the pre-operation checks
each time you use the vehicle to make
sure it is in safe operating condition.
Failure to inspect or maintain the vehi-
cle properly increases the possibility of
an accident or equipment damage.
See page 4-1 for a list of pre-operation
checks.
This scooter is designed to carry
the operator and a passenger.
TIPAlthough this scooter is designed to
carry a passenger, always comply with
the local regulations.The failure of motorists to detect
and recognize scooters in traffic is
the predominating cause of auto-
mobile/scooter accidents. Manyaccidents have been caused by
an automobile driver who did not
see the scooter. Making yourself
conspicuous appears to be very
effective in reducing the chance of
this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you are
approaching and passing
through intersections, since in-
tersections are the most likely
places for scooter accidents to
occur.
• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
• Never maintain a scooter with-
out proper knowledge. Contact
an authorized scooter dealer to
inform you on basic scooter
maintenance. Certain mainte-
nance can only be carried out
by certified staff.

3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately
wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may
deteriorate painted surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15152
Gasoline is poisonous and can cau-
se 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. Ifgasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your
clothes.
EAUM2731
Your Yamaha engine has been de-
signed to use premium unleaded gas-
oline with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.
EAU13434
Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire 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 sys-
tem has cooled down before
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.

and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWA11152
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage.
Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures provided in
this manual, have the vehicle inspected by a Yamaha dealer.Before using this vehicle, check the following points:

PERIODIC MAINTENANCE AND ADJUSTMENT
6-1

EAU17245
Periodic inspection, adjustment, and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. Safety is an obligation of the
vehicle owner/operator. The most im-
portant 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, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10322
Failure to properly maintain the vehi-
cle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer perform
service.
WARNING
EWA15123
Turn off the engine when performing
maintenance unless otherwise
specified.
A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.
Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-3 for more in-
formation about carbon monox-
ide.
WARNING
EWA15461
Brake discs, calipers, drums, and
linings can become very hot during
use. To avoid possible burns, let
brake components cool before
touching them.
EAU17303
Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replace-
ment, or repair of the emission control
devices and systems may be per-
formed by any repair establishment or
individual that is certified (if applicable).
Yamaha dealers are trained and
equipped to perform these particular
services.

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 tech-
nical skills.
