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 dif -
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 traffi c, and
then slowly turn the throttle grip
(on the right) in order to take off.

TroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting chart
represents a quick and easy pro-
cedure for checking these vital sys-
tems yourself. However, should your
scooter require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools, expe-
rience, and know-how to service the
scooter properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
EWA15141
WARNING
When checking the fuel system, do
not smoke, and make sure there
are no open ames or sparks in
