Braking
WARNING
EWA10301
Avoid braking hard or suddenly
(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 difficult.
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.Front

Periodic maintenance and adjustment

EAUS1824
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 todeath. See page 1-2 for more in-
formation about carbon monox-
ide.
WARNING
EWA10331
This scooter is designed for use on
paved roads only. If this scooter is
operated in abnormally dusty, mud-
dy or wet conditions, the air filter el-
ement should be cleaned or
replaced more frequently, otherwise
rapid engine wear may result. Con-
sult a Yamaha dealer for proper
maintenance intervals.
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.

TIP
Engine air filters and V-belt air filter
• This model’s engine air filters are equipped with disposable oil-coated pa-
per elements, which must not be cleaned with compressed air to avoid
damaging them.
• The engine air filter elements need to be replaced and the V-belt air filter
element needs to be serviced more frequently when riding in unusually wet
or dusty areas.
Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cyl-
inders and calipers, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.
27*Moving parts and

WARNING
EWA10512
Never overload your vehicle. Opera-
tion of an overloaded vehicle could
cause an accident.
Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.
TIP
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.
WARNING
EWA10472
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle 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 to do so.
Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimal
characteristics.
Tire information
This model is equipped with tubeless
tires and rubber tire air valves.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
Tire air pressure (measured on cold
tires):
1 person:
Front:
220 kPa (2.20 kgf/cm², 32 psi)
Rear:
250 kPa (2.50 kgf/cm², 36 psi)

Checking the front and rear
brake lever free play
Front
Rear
There should be no free play at the
brake lever ends. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
A soft or spongy feeling in the brake
lever can indicate the presence of
air in the hydraulic system. If there is
air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish thebraking performance, which may re-
sult in loss of control and an acci-
dent.

Adjusting the rear brake lock
cable
Periodically check the rear brake lock
cable length and adjust if necessary.
1. Release the rear brake lock lever.
2. To increase the rear brake lock ca-
ble length, turn the adjusting nut at
the rear brake caliper in direction
(a). To decrease the rear brake
lock cable length, turn the adjust-
ing nut in direction (b).
3. Confirm that the rear brake lock
lever (page 4-14) functions prop-
erly and that the rear wheel rotates
freely when unlocked.
WARNING
EWA20290
If proper adjustment cannot be ob-
tained as described, have a Yamaha
dealer make this adjustment.
EAUM3970
Checking the rear brake lock
The rear brake lock must be checked
at the intervals specified in the periodic
maintenance and lubrication chart.
1. Adjust the rear brake lock cable.
2. Apply the rear brake lock, and
then try to push the vehicle to con-
firm that the rear brake lock func-
tions properly.
3. The rear brake lock caliper is pro-
vided with wear pad indicator
grooves, which allow you to check
the brake pad wear without 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 almost disappeared, have a
Yamaha dealer replace the brake
pads as a set and check the rear
brake lock.
