SAFETY INFORMATION
SCOOTERS ARE SINGLE TRACK
VEHICLES. THEIR SAFE USE AND
1
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.
EAUT1010
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.
• Use extra caution when approaching and passing through
intersections, since intersections are the most likely places
for scooter accidents to occur.
1-1
• Ride where other motorists can
see you. Avoid riding in another motorist’s blind spot.
● Many accidents involve inexpe-
rienced 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 cau-
sed by error of the scooter operator. A typical error made by the
operator is veering wide on a turn
due to EXCESSIVE SPEED or
under cornering (insufficient lean
angle for the speed).
• Always obey the speed limit
SAFETY INFORMATION
t
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 hel-
met.
● 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.
1-2
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:
Loading
The total weight of the operator, passenger, accessories and cargo must
not exceed the maximum load limit of
CS50Z 158kg (348,39lb), CS50 161kg
(355lb). When loading within this
weight limit, keep the following in
mind:
1
t
SAFETY INFORMATION
● Cargo and accessory weight
should be kept as low and close
1
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 “Loading” 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.
• 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 scoo-
1-3
ter 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.
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gasoline on the engine or exhaust
system when refueling.
SAFETY INFORMATION
t
• 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 gasoli-
ne, 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.
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
corner 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
1-4
EAU10360
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 lining could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.
● 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. Use a strong
cord to secure any luggage to the
carriers. A loose load will affect
the stability of the scooter and
could divert your attention from
the road.
