prising the sidestand switch and brake
light switches) has the following func-
tions.
It prevents starting when the side-
stand is up, but neither brake is ap-
plied.
It prevents starting when either
brake is applied, but the sidestand
is still down.
It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according

OPERATION AND IMPORTANT RIDING POINTS
EAU15970
WARNING
EWA11250
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
For safety, always start the en-
gine with the centerstand down.
When the centerstand is down
and the engine is idling, keep
your hands and feet away from
the rear wheel.

FrontRear
WARNING
EWA10300
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.
