SAFETY INFORMATION

1 Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit of
180 kg (397 lb). When loading within
this weight limit, keep the following in
mind:

Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Make sure
to distribute the weight as evenly
as possible on both sides of the
scooter to minimize imbalance or
instability.


Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.


Never attach any large or heavy
items to the handlebar, front fork,
or front fender. Such items can
create unstable handling or a slow
steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot testall other accessories that may be avail-
able, you must personally be responsi-
ble for the proper selection, installation
and use of non-Yamaha accessories.
Use extreme caution when selecting
and installing any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.


Never install accessories or carry
cargo that would impair the perfor-
mance of your scooter. Carefully
inspect the accessory before using
it to make sure that it does not in
any way reduce ground clearance
or cornering clearance, limit sus-
pension travel, steering travel or
control operation, or obscure lights
or reflectors.
Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
weight distribution or aerody-
namic changes. If accessories
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodynamic
effects. Wind may attempt to lift
the scooter, or the scooter may
become unstable in cross
winds. These accessories may
also cause instability when
passing or being passed by
large vehicles.
Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.


Use caution when adding electri-
cal accessories. If electrical acces-
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.

1Gasoline 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 main
switch. 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 immediately.
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.
