WARNING
●Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thoroughly
understand.
●Never start the engine or ope-
rate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of cons-
ciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
●For safety, always start the
engine with the centerstand
down.
EAU16561
Starting a cold engineECA10250
CAUTION:
See page 5-4 for engine break-in
instructions prior to operating the
vehicle for the first time.
1. Turn the key to “h”, and when
the oil level warning light comes
on, turn it to “f”.
ECA10240
CAUTION:
If the oil level warning light does
not come on, have a Yamaha dealer
check the electrical circuit.
2. Close the throttle completely.
3. While applying the front or rear
brake, start the engine by pus-hing the start switch or by pus-
hing 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 using the
kickstarter.
ECA11040
CAUTION:
For maximum engine life, never
accelerate hard when the engine is
cold!

NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4~1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
EAU20061
Final transmission oil
The final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final trans-
mission oil must be changed as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm up the
final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the oil filler cap and
drain bolt to drain the oil from the
final transmission case.
1. Final transmission oil filler cap
2. Final transmission oil drain bolt
5. Install the final transmission oil
drain bolt, and then tighten it to
the specified torque.
6. Add the specified amount of the
recommended final transmission
oil, and then install and tighten
the oil filler cap.
Tightening torque:
Final transmission oil drain bolt:
18 Nm (1.8 m•kgf, 13.0 ft•lbf)
Tightening torque:
Spark plug:
20 Nm (2.0 m•kgf, 14.5 ft•lbf)

WARNING
●Make sure that no foreign
material enters the final trans-
mission case.
●Make sure that no oil gets on
the tire or wheel.
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAUS1200
Coolant (only for liquid-
cooled models)
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM2101
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
NOTE:
●The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
●Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level through
the check window.
NOTE:
The coolant should be between the
minimum and maximum level marks.
1. Coolant level window
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove the
cowling A. (See page 6-5.)
4. Open the reservoir cap, and then
add coolant to the maximum
level mark.
Coolant reservoir capacity:
0.25 L (0.26 US qt) (0.22 Imp.qt)
Recommended final transmission
oil:
See page 8-1.
Oil quantity:
0.11 L (0.12 US qt) (0.10 Imp.qt)

EAU32344
Checking the brake fluid
level
1. Minimum level mark
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
●When checking the fluid level,
make sure that the top of themaster cylinder is level by turning
the handlebars.
●Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
●Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
●Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
●As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
Recommended brake fluid:
