GIVE SAFETY THE RIGHT OF WAY

EAU03099
Further safe-riding pointsSafe-riding points8Be sure to signal clearly when making turns.
8Braking 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.
8Slow down as you approach a corner or turn. Once you have completed a turn, accelerate slowly.
8Be careful when passing parked cars. A driver might not see you and open a door in your path.
8Railroad crossings, streetcar rails, iron plates on road construction sites, and manhole covers
become extremely slippery when wet. Slow down and cross them with caution. Keep the scooter
upright, otherwise it could slide out from under you.
8The brake pads could get wet when you wash the scooter. After washing the scooter, check the
brakes before riding.
8Always wear a helmet, gloves, trousers (tapered around the cuff and ankle so they do not flap),
and a bright colored jacket.
8Do not carry too much luggage on the scooter. An overloaded scooter is unstable.

Checking the front and rear
brake padsFront and rear brake pads, checkingThe front and rear brake pads must
be checked for wear at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU03938
Front brake pads
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear
without 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
almost disappeared, have a Yamaha
dealer replace the brake pads as a
set.

Checking the brake fluid
levelBrake fluid level, checkingInsufficient 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 leak-
age.

Rear brake pads
1. Remove the rear brake caliper
by removing the bolts.
2. Check each rear brake pad for
damage and measure the lining
thickness. If a brake pad is dam-
aged or if the lining thickness is
less than 0.8 mm, have a
Yamaha dealer replace the
brake pads as a set.
3. Install the rear brake caliper by
installing the bolts, then tighten-
ing them to the specified torque.

6 Observe these precautions:
8When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.

EAU03976
Changing the brake fluidBrake fluid, changingHave a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the master
cylinders and calipers as well as the
brake hoses replaced at the intervals
listed below or whenever they are
damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years. 8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be 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.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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.
