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 then remove the engine oil
drain bolt and its gasket to drain
the oil from the crankcase.
5. Install the engine oil drain bolt and
its new gasket, and then tighten
the bolt to the specified torque.
6. Refill with the specified amount of

higher quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
●
Be sure no foreign material en-
ters the crankcase.
7. 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.
8. Turn the engine off, and then
check the oil level and correct it if
necessary.

6 Cleaning the V-belt case air filter el-
ement
1. Place the scooter on the center-
stand.
2. Remove the screws, and then pull
the V-belt case air filter element
cover outward and away from V-
belt case.
3. Pull the V-belt case air filter ele-
ment out, and then clean it with
solvent. After cleaning, remove the
remaining solvent by squeezing
the element. WARNING! Use
only a dedicated parts cleaning
solvent. To avoid the risk of fire
or explosion, do not use gaso-
line or solvents with a low flashpoint.
[EWA10431]
NOTICE: To avoid
damaging the air filter element,
handle it gently and carefully,
and do not twist it.

4. Apply oil of the recommended type
to the entire surface of the sponge
material, and then squeeze the ex-
cess oil out.
TIPThe air filter element should be wet but
not dripping.5. Insert the element into the V-belt
case.

Checking the brake fluid level Before riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the top
of the reservoir level. Replenish the
brake fluid if necessary.
WARNING
EWA15980
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
●
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
●
Clean the filler cap before re-
moving. Use only DOT 3 or DOT
4 brake fluid from a sealed con-
tainer.
●
Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
●
Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 3 or DOT 4 may
result in a harmful chemical re-
action.
●
Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always clean
up spilled fluid immediately.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
tem leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
further riding.

Replacing the fuse The fuse holder is located behind panel
B. (See page 6-7.)
If the fuse is blown, replace it as fol-
lows.
1. Turn the key to “OFF” and turn off
all electrical circuits.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to
avoid causing extensive dam-
age to the electrical system and
possibly a fire.
[EWA15131]
3. Turn the key to “ON” and turn on
the electrical circuits to check if the
devices operate.
4. If the fuse immediately blows
again, have a Yamaha dealer
check the electrical system.

Replacing the headlight bulb If the headlight bulb burns out, replace
it as follows.NOTICE
ECA10650
Take care not to damage the follow-
ing parts:●
Headlight bulb
Do not touch the glass part of
the headlight bulb to keep it free
from oil, otherwise the transpar-
ency of the glass, the luminosity
of the bulb, and the bulb life will
be adversely affected. Thor-
oughly clean off any dirt and fin-
gerprints on the headlight bulb
using a cloth moistened with al-
cohol or thinner.
●
Headlight lens
Do not affix any type of tinted
film or stickers to the headlight
lens.
Do not use a headlight bulb of a
wattage higher than specified.
