SAFETY INFORMATION
1-2
1

Always signal before turning or
changing lanes. Make sure that
other motorists can see you.

The posture of the operator and
passenger is important for proper
control.

The operator should keep both
hands on the handlebar and
both feet on the footboard during
operation to maintain control of
the scooter.

The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger footrests.

Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.

Never ride under the influence of
alcohol or other drugs.

This scooter is designed for
on-road use only. It is not suitable
for off-road use.
Protective apparel
The majority of fatalities from scooter
accidents are the result of head inju-ries. The use of a safety helmet is the
single most critical factor in the preven-
tion or reduction of head injuries.

Always wear an approved helmet.

Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision which could delay seeing
a hazard.

The use of a jacket, substantial
shoes, trousers, gloves, etc., is ef-
fective in preventing or reducing
abrasions or lacerations.

Never wear loose-fitting clothes,
otherwise they could catch on the
control levers or wheels and cause
injury or an accident.

Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protec-
tive clothing that covers your legs,
ankles, and feet.

Passengers should also observe
the above precautions.
Modifications
Modifications made to this scooter notapproved by Yamaha, or the removal of
original equipment, may render the
scooter unsafe for use and may cause
severe personal injury. Modifications
may also make your scooter illegal to
use.
Loading and accessories
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution of
the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accesso-
ries to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here are some
general guidelines to follow if loading
cargo or adding accessories to your
scooter:
Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.

Maximum load:
172 kg (379 lb)

SAFETY INFORMATION

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 immediate-
ly. If any gasoline spills on your
skin or clothing, immediately wash
the affected area with soap and
water and change your clothes.

EAU16780
Acceleration and deceleration
The speed can be adjusted by opening
and closing the throttle. To increase the

(a). To reduce the speed, turn the throt-
tle grip in direction (b).
EAU16791
Braking
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.
WARNING

EWA10300

Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.

Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.

Keep in mind that braking on a
wet road is much more difficult.

Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
