OPERATION AND IMPORTANT RIDING POINTS
EAU16780
Acceleration and decelera-
tion
(a)(b)
The speed can be adjusted by open-
ing and closing the throttle. To in-
crease the speed, turn the throttle grip
in direction (a). To reduce the speed,
turn the throttle grip in direction (b).
EAU16793
Braking
EWA10300
WARNING
● Avoid braking hard or sud-
denly (especially when leaning
over to one side), otherwise the
scooter may skid or overturn.● Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.● Keep in mind that braking on
a wet road is much more diffi-
cult.● Ride slowly down a hill, as
braking downhill can be very
dif cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EAU16761
Starting offTIPBefore starting off, allow the engine to
warm up.
1. While pulling the rear brake lever
with your left hand and holding
the grab bar with your right hand,
push the scooter off the center-
stand.
2. Sit astride the seat, and then ad-
just the rear view mirrors.
3. Switch the turn signals on.
4. Check for oncoming traffic, and
then slowly turn the throttle grip
(on the right) in order to take off.
5. Switch the turn signals off.

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.

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.

WARNING
● Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.● The replacement of all wheel
and brake related parts, includ-
ing the tires, should be left to
a Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
EAU21962
Cast wheelsTo maximize the performance, dura-
bility, and safe operation of your ve-
hicle, note the following points regard-
ing the specifi ed wheels.● The wheel rims should be
checked for cracks, bends, warp-
age or other damage before each
ride. If any damage is found,
have a Yamaha dealer replace
the wheel. Do not attempt even
the smallest repair to the wheel.
A deformed or cracked wheel
must be replaced.● The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.

1. Rear brake lever free playThe brake lever free play should mea-
sure 10 ~ 20 mm (0.039 ~ 0.079 in) as
shown. Periodically check the brake
lever free play and, if necessary, ad-
just it as follows.
To increase the brake lever free play,
turn the adjusting nut at the brake
shoe plate in direction (a). To de-
crease the brake lever free play, turn
the adjusting nut in direction (b).

WARNING
If proper adjustment cannot be ob-
tained as described, have a Yama-
ha dealer make this adjustment.
EAU37913
Checking the brake lever free
playThere should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
EWA14211
WARNING
A soft or spongy feeling in the
brake lever can indicate the pres-
ence of air in the hydraulic system.
If there is air in the hydraulic sys-
tem, have a Yamaha dealer bleed
the system before operating the
vehicle. Air in the hydraulic system
will diminish the braking perfor-
mance, which may result in loss of
control and an accident.
