For proper handling, read and
understand the following informa-
tion before handling the shock
absorber. The manufacturer can-
not be held responsible for proper-
ty damage or personal injury that
may result from improper han-
dling.
8Do not tamper with or attempt
to open the gas cylinder.
8Do not subject the shock
absorber to an open flame or
other high heat sources, other-
wise it may explode due to
excessive gas pressure.
8Do not deform or damage the
gas cylinder in any way, as
this will result in poor damp-
ing performance.

TiresTiresTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EW000082
w8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the
ambient temperature).
8The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passen-
ger, cargo, and accessories
approved for this model.
EWA00040
wBecause loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your scooter, you should
keep the following precautions in
mind.
8NEVER OVERLOAD THE
SCOOTER! Operation of an
overloaded scooter may result
in tire damage, loss of control,
or severe injury. Make sure
that the total weight of rider,
passenger, cargo, and acces-sories does not exceed the
specified maximum load for
the vehicle.
8Do not carry along loosely
packed items, which can shift
during a ride.
8Securely pack the heaviest
items close to the center of the
scooter and distribute the
weight evenly on both sides.
8Adjust the tire air pressure
with regard to the load.
8Check the tire condition and
air pressure before each ride.

TroubleshootingTroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter
require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools,
experience, 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.
EC000105
cCDo not touch the glass part of the
headlight bulb to keep it free from
oil, otherwise the transparency of
the glass, the luminosity of the
bulb, and the bulb life will be
adversely affected. Thoroughly
clean off any dirt and fingerprints
on the headlight bulb using a cloth
moistened with alcohol or thinner.4. Install the bulb cover, and then
connect the coupler.
5. Have a Yamaha dealer adjust
the headlight beam if necessary.
