PRE-OPERATION CHECKS
ITEM CHECKS PAGE
NOTE :
Pre-operation checks should be made each time the scooter is used. Such an inspection can be accomplished in a very
short time; and the added safety it assures is more than worth the time involved.
EWA00033
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the scooter.
4-2 • Check for damage.
Wheels and Tires• Check tire condition and tread depth.
6-9 — 6-11
• Check air pressure.
• Correct if necessary.
Brake levers• Make sure that operation is smooth.
3-4 — 3-5
• Lubricate lever pivoting points if necessary.
Centerstand• Make sure that operation is smooth.
6-15
• Lubricate pivot if necessary.
Chassis-fasteners• Make sure that all nuts, bolts and screws are properly tightened.
—
• Tighten if necessary.
Instruments, lights• Check operation.
3-1 — 3-4, 6-20 — 6-21
signals and switches• Correct if necessary.
Battery• Check fluid level.
6-17
• Fill with distilled water if necessary.

OPERATION AND IMPORTANT RIDING POINTS
5
EAU01118
EW000129
•Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or
function that you do not
thoroughly understand.
•Never start the engine or
operate it in a closed area for
any length of time. Exhaust fu-
mes are poisonous, and
inhaling them can cause loss of
consciousness and death
within a short time. Always
make sure that there is
adequate ventilation.
•For safety, always start the
engine with the centerstand
down.

Starting the engine
1. Turn the key to “
*
”, then when
the oil level warning light comes
on, turn it to “
”.
EC000045
If the oil level warning light does not
come on, have a Yamaha dealer
check the electrical circuit.
2. Turn the starter (choke) on and
completely close the throttle. (See
page 3-7 for starter (choke)
operation.)3. Start the engine by pushing the
start switch or by pushing the
kickstarter lever down, while
applying the front or rear brake.
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 using
the kickstarter.
4. After starting the engine, move the
starter (choke) knob/lever back
halfway.

Troubleshooting
Although 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 procedure
for checking these vital systems
yourself. However, should your scoo-
ter require any repair, take it to a
Yamaha dealer, whose skilled
technicians have the necessary tools,
experience, and know-how to service
the scooter properly.
Use only genuine Yamaha replacement
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.

SCOOTER CARE AND STORAGE
7
•Do not use high-pressure
washers or steam-jet cleaners
since they cause water
seepage and deterioration in
the following areas: seals (of
wheel and swingarm bearings,
fork and brakes), electric
components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
•For scooters equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning
compounds for plastic may
leave scratches on the
windshield. Test the product on
a small hidden part of the
windshield to make sure that it
does not leave any marks. If the
windshield is scratched, use a
quality plastic polishing
compound after washing.
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain, near the sea
or on salt-sprayed roads
Since sea salt or salt sprayed on the
roads during winter are extremely cor-
rosive in combination with water, carry
out the following steps after each ride
in the rain, near the sea or on salt-
sprayed roads.
NOTE :
Salt sprayed on roads in the winter may
remain well into spring.1. Clean the scooter with cold water
and a mild detergent after the
engine has cooled down.
ECA00012
Do not use warm water since it
increases the corrosive action of the
salt.
2. Apply a corrosion protection spray
on all metal, including chrome-
and nickel-plated, surfaces to
prevent corrosion.
