Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
The posture of the operator and
passenger is important for proper
control.
The operator should keep both
hands on the handlebar and
both feet on the operator foo-
trests during operation to
maintain control of the scooter.
The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger foo-
trests. Never carry a passenger
unless he or she can firmly pla-
ce both feet on the passenger
footrests.
Never ride under the influence of
alcohol or other drugs.
This scooter is designed for on-
road use only. It is not suitable for
off-road use.Protective Apparel
The majority of fatalities from scooter
accidents are the result of head inju-
ries. The use of a safety helmet is the
single most critical factor in the pre-
vention or reduction of head injuries.
Always wear an approved hel-
met.
Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impair-
ment of vision that could delay
seeing a hazard.
The use of a jacket, substantial
shoes, trousers, gloves, etc., is
effective in preventing or redu-
cing abrasions or lacerations.
Never wear loose-fitting clothes,
otherwise they could catch on
the control levers or wheels and
cause injury or an accident.
Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust sys-
tem become very hot during or
after operation and can cause
burns.
A passenger should also observe
the above precautions.Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause heada-
ches, dizziness, drowsiness, nausea,
confusion, and eventually death.
Carbon Monoxide is a colorless,
odorless, tasteless gas which may be
present even if you do not see or
smell any engine exhaust. Deadly
levels of carbon monoxide can collect
rapidly and you can quickly be over-
come and unable to save yourself.
Also, deadly levels of carbon monoxi-
de can linger for hours or days in
enclosed or poorly ventilated areas. If
you experience any symptoms of car-
bon monoxide poisoning, leave the
area immediately, get fresh air, and
SEEK MEDICAL TREATMENT.
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can
rapidly reach dangerous levels.
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.

EAUS1820
Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. Safety is an obligation
of the vehicle owner/operator. The
most important points of vehicle ins-
pection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, depending on
the weather, terrain, geographical
location, and individual use, the main-
tenance intervals may need to be
shortened.
EWA10321
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.
EWA15121
Turn off the engine when perfor-
ming maintenance unless otherwi-
se 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 servi-
cing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-1 for more
information about carbon
monoxide.
EWA10330
This scooter is designed for use on
paved roads only. If this scooter is
operated in abnormally dusty,
muddy or wet conditions, the air fil-
ter element should be cleaned or
replaced more frequently, otherwi-
se rapid engine wear may result.Consult a Yamaha dealer for proper
maintenance intervals.

EAU22392
Checking the front and rear
brake pads
The front and rear brake pads must
be checked for wear at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU22430
Front brake pads
1. Wear indicator groove
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear wit-
hout having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the
wear indicator grooves have almostdisappeared, have a Yamaha dealer
replace the brake pads as a set.
EAU22520
Rear brake pads
1. Wear indicator groove
The rear brake is provided with a
check plug, which, if it is removed,
allows you to check the brake pad
wear without disassembling the bra-
ke. To check the brake pad wear,
check the position of the wear indica-
tor while applying the brake. If a bra-
ke pad has worn to the point that the
wear indicator almost touches the
brake disc, have a Yamaha dealer
replace the brake pads as a set.
