SAFETY INFORMATION

sories exceed the capacity of the
scooter’s electrical system an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Gasoline and exhaust gas

GASOLINE IS HIGHLY FLAMMA-
BLE:

Always turn the engine off when
refueling.

Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.

Never refuel while smoking or in
the vicinity of an open flame.

Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within a
short time. Always operate your
scooter in an area that has ade-
quate ventilation.

Always turn the engine off before
leaving the scooter unattended
and remove the key from the mainswitch. When parking the scooter,
note the following:

The engine and exhaust system
may be hot, therefore, park the
scooter in a place where pedes-
trians or children are not likely to
touch these hot areas.

Do not park the scooter on a
slope or soft ground, otherwise it
may fall over.

Do not park the scooter near a
flammable source (e.g., a kero-
sene heater, or near an open
flame), otherwise it could catch
fire.

If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediate-
ly. If any gasoline spills on your
skin or clothing, immediately wash
the affected area with soap and
water and change your clothes.
EAU10371
Further safe-riding points

Be sure to signal clearly when
making turns.

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 could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

The annual checks must be performed every year, except if a kilometer-based maintenance is performed in-
stead.

From 50000 km, repeat the maintenance intervals starting from 10000 km.

Checking the front and rear
brake pads
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance 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.
EAU34210
Rear brake pads
Have a Yamaha dealer check each
rear brake pad for damage and mea-
sure the lining thickness and if neces-
sary, replace them as a set.
EAU22580
Checking the brake fluid level

Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing 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 fluid 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 brake
fluid reservoir is level.

Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.

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 brake fluid reservoir whenrefilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.

Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.

As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU22730
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.

Brake hoses: Replace every four
years.
