SAFETY INFORMATION
EAUT1010
SCOOTERS ARE SINGLE TRACK
VEHICLES. THEIR SAFE USE AND
OPERATION ARE DEPENDENT
UPON THE USE OF PROPER
RIDING TECHNIQUES AS WELL AS
THE EXPERTISE OF THE OPERATOR. EVERY OPERATOR SHOULD
KNOW THE FOLLOWING REQUIREMENTS BEFORE RIDING THIS
SCOOTER.
HE OR SHE SHOULD:
● OBTAIN THOROUGH INSTRUC-
TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
SCOOTER OPERATION.
● OBSERVE THE WARNINGS
AND MAINTENANCE REQUIREMENTS IN THE OWNER’S MANUAL.
● OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.
● OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
Safe riding
● Always make pre-operation
checks. Careful checks may help
prevent an accident.
● This scooter is designed to carry
the operator and passenger.
NOTE:
Although this scooter is designed to
carry a passenger, always comply with
the local regulations.
● The failure of motorists to detect
and recognize scooters in traffic is
the predominating cause of automobile/scooter accidents. Many
accidents have been caused by an
automobile driver who did not see
the scooter. Making yourself conspicuous appears to be very effective in reducing the chance of this
type of accident.
Therefore:
• Wear a brightly colored jacket.
1-1
• Use extra caution when approaching and passing through
intersections, since intersections are the most likely places
for scooter accidents to occur.
• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
● Many accidents involve inexperi-
enced operators. In fact, many operators who have been involved in
accidents do not even have a current driver’s license.
• Make sure that you are qualified
and that you only lend your
scooter to other qualified operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you practice riding your scooter where
there is no traffic until you have
become thoroughly familiar with
the scooter and all of its controls.
● Many accidents have been
caused by error of the scooter operator. A typical error made by the
1
SAFETY INFORMATION
operator is veering wide on a turn
due to EXCESSIVE SPEED or under cornering (insufficient lean an-
1
gle for the speed).
• Always obey the speed limit and
never travel faster than warranted by road and traffic conditions.
• 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 injuries. The use of a safety helmet is the
single most critical factor in the prevention 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 effective 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 protective clothing that covers your legs,
ankles, and feet.
● Passengers should also observe
the above precautions.
Modifications
Modifications made to this scooter not
approved 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 accessories 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:
1-2
SAFETY INFORMATION
Loading
The total weight of the operator, passenger, 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 accessories 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 test
all other accessories that may be available, you must personally be responsible 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 performance 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 suspension travel, steering travel or
control operation, or obscure lights
or reflectors.
• Accessories fitted to the handlebar or the front fork area can
create instability due to improper
weight distribution or aerodynamic 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.
1-3
• 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 displace the operator from his or
her normal riding position. This
improper position limits the freedom of movement of the operator and may limit control ability,
therefore, such accessories are
not recommended.
● Use caution when adding electri-
cal accessories. If electrical accessories 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.
1
SAFETY INFORMATION
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMA-
BLE:
1
• Always turn the engine off when
refueling.
• Take care not to spill any gasoline 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 poisonous and may cause loss of
consciousness and death within a
short time. Always operate your
scooter in an area that has adequate 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 pedestrians 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 kerosene 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 completed 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 become extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter upright, 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.
1-4
● Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a bright colored jacket.
● Do not carry too much luggage on
the scooter. An overloaded scooter is unstable.
