PERIODIC MAINTENANCE AND MINOR REPAIR
EAU17280
Safety is an obligation of the owner. Pe-
riodic inspection, adjustment and lubri-
cation will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON THE
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.
WARNING
EWA10320
If you are not familiar with mainte-
nance work, have a Yamaha dealer
do it for you.
WARNING
EWA10330
This scooter is designed for use on
paved roads only. If this scooter isoperated in abnormally dusty, mud-
dy or wet conditions, the air filter el-
ement should be cleaned or
replaced more frequently, otherwise
rapid engine wear may result. Con-
sult a Yamaha dealer for proper
maintenance intervals.
EAU17390
Owner’s tool kit
The owner’s tool kit is located under the
seat. (See page 3-17.)
The service information included in this
manual and the tools provided in the
owner’s tool kit are intended to assist
you in the performance of preventive
maintenance and minor repairs. How-
ever, additional tools such as a torque
wrench may be necessary to perform
certain maintenance work correctly.
NOTE:
If you do not have the tools or experi-
ence required for a particular job, have
1. Helmet holding cable
2. Owner’s tool kit

NOTE:
Air filter
This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with com-
pressed air to avoid damaging it.
The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
Hydraulic brake service
Regularly check and, if necessary, correct the brake fluid level.
Every two years replace the internal components of the brake master cylinders and calipers, and change the brake
fluid.
Replace the brake hoses every four years and if cracked or damaged.

Engine oil and oil filter
cartridge
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on the center-
stand.
CAUTION:
ECA11290
The engine must be cold before pro-
ceeding with the oil level check, oth-
erwise the check will result in a false
reading.
NOTE:
Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in a
false reading.
2. Start the engine, warm it up for two
minutes, and then turn it off.
3. Wait two minutes until the oil set-tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.
NOTE:
The engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment)
1. Place the vehicle on a level sur-
face.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.
4. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.

5. Check the washer and O-ring for
damage and replace them if nec-
essary.
NOTE:
Skip steps 6–8 if the oil filter cartridge is
not being replaced.
6. Remove the oil filter cartridge with
an oil filter wrench.
NOTE:
An oil filter wrench is available at a
Yamaha dealer.
7. Apply a thin coat of engine oil to
the O-ring of the new oil filter car-
tridge.
NOTE:
Make sure that the O-ring is properly
seated.
8. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.

9. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
10. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.
NOTE:
Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
CAUTION:
ECA11620
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-
rial enters the crankcase.
11. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
12. Turn the engine off, and then
check the oil level and correct it if
necessary.
13. Reset the oil change indicator.
(See page 3-9.)
NOTE:
If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must be
reset after the oil change for the next

9coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
WARNING
EWA10380
Never attempt to remove the radiator
cap when the engine is hot.
6. Install the coolant reservoir cover
by installing the screw.
7. Place the right floorboard mat in
the original position.
NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page
6-35 for further instructions.

Replacing the air filter element
The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
To replace the air filter element
1. Remove panels C and D. (See
page 6-7.)
2. Remove the air filter case cover by
removing the screws.
3. Pull the air filter element out.4. Insert a new air filter element into
the air filter case.
CAUTION:
ECA10480
Make sure that the air filter ele-
ment is properly seated in the
air filter case.
The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.
5. Install the air filter case cover by in-
stalling the screws.
6. Install the panels.
