Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. Safety is an obligation
of the vehicle owner/operator. The
most important points of vehicle ins-
pection, 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
general guide under normal riding
conditions. However, depending on
the weather, terrain, geographical
location, and individual use, the main-
tenance intervals may need to be
shortened.
EWA10321
Failure to properly maintain the
vehicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EWA15121
Turn off the engine when perfor-
ming maintenance unless otherwi-
se specified.
A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.
Running the engine while servi-
cing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-1 for more
information about carbon
monoxide.

This scooter is designed for use on
paved roads only. If this scooter is
operated in abnormally dusty,
muddy or wet conditions, the air fil-

of the recommended final trans-
mission oil. WARNING! Make
sure that no foreign material
enters the final transmission
case. Make sure that no oil
gets on the tire or wheel.
[EWA11311]

filler cap and its new O-ring, and
then tighten the oil filler cap.
9. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.

Coolant
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.
EAUS1670
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
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.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Maximum level mark
2. Minimum level mark
3. Coolant level check window
3. If the coolant is at or below the
minimum level mark, lift up the
right floorboard mat as shown.

NOTICE: If coolant is not avai-
lable, use distilled water or soft
tap water instead. Do not use
hard water or salt water since it
is harmful to the engine. If
water has been used instead of
coolant, replace it with coolant
as soon as possible, otherwise
the cooling system will not be
protected against frost andcorrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.

Front brake pads
1. Wear indicator groove
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear wit-
hout having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the
wear indicator grooves have almostdisappeared, have a Yamaha dealer
replace the brake pads as a set.
