SAFETY INFORMATION
1-5
1
●
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
●
Secure the scooter with tie-downs
or suitable straps that are attached
to solid parts of the scooter, such
as the frame or upper front fork tri-
ple clamp (and not, for example, to
rubber-mounted handlebars or
turn signals, or parts that could
break). Choose the location for the
straps carefully so the straps will
not rub against painted surfaces
during transport.
●
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the
scooter will not bounce excessive-
ly during transport.
EAU45371
Further safe-riding points ●
Make sure to signal clearly when
making turns.
Left turn
Right turn
●
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.
●
Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.
●
Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
●
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.
●
The brake pads and linings could
get wet when you wash the scoot-
er. After washing the scooter,
check the brakes before riding.
●
Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a bright colored jacket.

EAU15596
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the inspection
and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWA11151
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage.
Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures provided in
this manual, have the vehicle inspected by a Yamaha dealer.Before using this vehicle, check the following points:
ITEM CHECKS PAGE
Fuel Check fuel level in fuel tank.
Refuel if necessary.
Check fuel line for leakage.3-6
Engine oil Check oil level in engine.
If necessary, add recommended oil to specified level.
Check vehicle for oil leakage.6-10
Final transmission oil Check vehicle for oil leakage. 6-12
Front brake Check operation.
If soft or spongy, have Yamaha dealer bleed hydraulic system.
Check brake pads for wear.
Replace if necessary.
Check fluid level in reservoir.
If necessary, add specified brake fluid to specified level.
Check hydraulic system for leakage.6-19, 6-20
Rear brake Check operation.
Lubricate cable if necessary.
Check lever free play.
Adjust if necessary.6-18, 6-19

WARNING
EWA10650
If proper adjustment cannot be ob-
tained as described, have a Yamaha
dealer make this adjustment.
EAU22380
Checking the front brake pads
and rear brake shoes The front brake pads and the rear brake
shoes must be checked for wear at the
intervals specified in the periodic main-
tenance and lubrication chart.
EAU22430
Front brake pads
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out 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 wearindicator grooves have almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22540
Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to dis-
assemble the brake. To check the
brake shoe wear, check the position of
the wear indicator while applying the
brake. If a brake shoe has worn to the
point that the wear indicator reaches
the wear limit line, have a Yamaha
dealer replace the brake shoes as a
set.

EAU37002
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.
