PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.
ITEM CHECKS PAGE
•Check fuel level in fuel tank.
Fuel•Refuel if necessary.3-6•Check fuel line for leakage.
•Check oil level in oil tank.
Two-stroke engine oil•If necessary, add recommended oil to specified level. 3-7•Check vehicle for oil leakage.
Final transmission oil•Check oil level and vehicle for oil leakage. 6-6
•Check operation.
•If soft or spongy, have Yamaha dealer bleed hydraulic system.
Front brake•Check fluid level in reservoir. 3-4, 6-11
•If necessary, add recommended brake fluid to specified level.
•Check hydraulic system for leakage.
•Check operation.
Rear brake•Check lever free play. 3-5, 6-11•Adjust if necessary.
•Make sure that operation is smooth.
Throttle grip•Check cable free play.

NOTE :
Pre-operation checks should be made each time the scooter is used. Such an inspection can be accomplished in a veryshort time; and the added safety it assures is more than worth the time involved.

If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operatingthe scooter.
4-2 •Check for damage.
Wheels and Tires•Check tire condition and tread depth.
6-9 — 6-10
•Check air pressure.
•Correct if necessary.
Brake levers•Make sure that operation is smooth.
3-4 — 3-5•Lubricate lever pivoting points if necessary.
Centerstand•Make sure that operation is smooth.
6-15•Lubricate pivot if necessary.
Chassis-fasteners•Make sure that all nuts, bolts and screws are properly tightened.
—•Tighten if necessary.
Instruments, lights•Check operation.

Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to
disassemble 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 dea-
ler replace the brake shoes as a set.

Checking the brake fluid levelInsufficient 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 brake fluid
level may indicate worn brake pads and/
or brake system leakage. If the brake
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 the
master cylinder is level by turning
the handlebars.
•
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Recommended brake fluid:
DOT 4
NOTE :
If DOT 4 is not available, DOT 3 can beused.•
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
•
Be careful that water does not en-
ter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and
lubrication chart. In addition, have the
brake hose replaced every four years
or whenever it is damaged or leaking.
EAU02962
Checking and lubricating the
cablesThe operation of all control cables and
the condition of the cables should be
checked before each ride, and the
cables and cable ends should be
lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or replace
it.
Recommended lubricant:
Engine oil
EW000112
Damage to the outer sheath may
interfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafeconditions.

•
Brake fluid may deteriorate painted
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.
