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 OPERA-
TOR. EVERY OPERATOR SHOULD
KNOW THE FOLLOWING REQUIRE-
MENTS 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 REQUIRE-
MENTS IN THE OWNER’S MAN-
UAL.


OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.


OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUALAND/OR WHEN MADE NECES-
SARY BY MECHANICAL CONDI-
TIONS.
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 withthe local regulations.

The failure of motorists to detect
and recognize scooters in traffic is
the predominating cause of auto-
mobile/scooter accidents. Many
accidents have been caused by an
automobile driver who did not see
the scooter. Making yourself con-
spicuous appears to be very effec-
tive in reducing the chance of this
type of accident.
Therefore:
Wear a brightly colored jacket.Use extra caution when ap-
proaching and passing through
intersections, since intersec-
tions 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 op-
erators who have been involved in
accidents do not even have a cur-
rent driver’s license.
Make sure that you are qualified
and that you only lend your
scooter to other qualified opera-
tors.
Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
We recommend that you prac-
tice riding your scooter where
there is no traffic until you have
become thoroughly familiar with
the scooter and all of its con-
trols.


Many accidents have been
caused by error of the scooter op-
erator. A typical error made by the

SAFETY INFORMATION
1-2
1operator is veering wide on a turn
due to EXCESSIVE SPEED or un-
der cornering (insufficient lean an-
gle for the speed).
Always obey the speed limit and
never travel faster than warrant-
ed 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 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 cancause 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 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 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:
