SAFETY INFORMATION

1Gasoline and exhaust gas


GASOLINE IS HIGHLY FLAMMA-
BLE:
Always turn the engine off when
refueling.
Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.
Never refuel while smoking or in
the vicinity of an open flame.


Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within a
short time. Always operate your
scooter in an area that has ade-
quate ventilation.


Always turn the engine off before
leaving the scooter unattended
and remove the key from the main
switch. When parking the scooter,
note the following:
The engine and exhaust system
may be hot, therefore, park the
scooter in a place where pedes-
trians or children are not likely to
touch these hot areas.Do not park the scooter on a
slope or soft ground, otherwise it
may fall over.
Do not park the scooter near a
flammable source (e.g., a kero-
sene heater, or near an open
flame), otherwise it could catch
fire.


If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately.
If any gasoline spills on your skin
or clothing, immediately wash the
affected area with soap and water
and change your clothes.
EAU10371
Further safe-riding points

Be sure to signal clearly when
making turns.


Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.


Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.


Be careful when passing parked
cars. A driver might not see you
and open a door in your path.


Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.


The brake pads could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

WARNING
EWA10870


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.
EAU16560
Starting the engineCAUTION:
ECA10250
See page 5-4 for engine break-in in-
structions prior to operating the ve-hicle for the first time.
1. Turn the key to “”, and when the
oil level warning light comes on,
turn it to “”.CAUTION:
ECA10240
If the oil level warning light does not
come on, have a Yamaha dealercheck the electrical circuit.
2. Close the throttle completely.3. While applying the front or rear
brake, start the engine by pushing
the start switch or by pushing the
kickstarter lever down.
NOTE:If the engine fails to start by pushing the
start switch, release the switch, wait a
few seconds, and then try again. Each
starting attempt should be as short as
possible to preserve the battery. Do not
crank the engine more than 5 seconds
on any one attempt. If the engine does
not start with the starter motor, try usingthe kickstarter.

EAU16791
Braking 1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.
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, slowdown 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.
EAU16820
Tips for reducing fuel
consumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Avoid high engine speeds during
acceleration.


Avoid high engine speeds with no
load on the engine.


Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
