Q SAFETY INFORMATION
EAU10260
SCOOTERS ARE SINGLE TRACK VE-
HICLES. THEIR SAFE USE AND OP-
ERATION ARE DEPENDENT UPON
THE USE OF PROPER RIDING TECH-
NIQUES AS WELL AS THE EXPER-
TISE OF THE OPERATOR. EVERY OP-
ERATOR SHOULD KNOW THE FOL-
LOWING REQUIREMENTS BEFORE
RIDING THIS SCOOTER.
HE OR SHE SHOULD:
8OBTAIN THOROUGH INSTRUC-
TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
SCOOTER OPERATION.
8OBSERVE THE WARNINGS AND
MAINTENANCE REQUIRE-
MENTS IN THE OWNER’S
MANUAL.
8OBTAIN QUALIFIED TRAINING IN
SAFE AND PROPER RIDING
TECHNIQUES.
8OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL AND/
OR WHEN MADE NECESSARY
BY MECHANICAL CONDITIONS.Safe riding
8Always make pre-operation checks.
Careful checks may help prevent
an accident.
8This scooter is designed to carry
the operator and passenger.
8The 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:
9Wear a brightly colored jacket.
9Use extra caution when
approaching and passing
through intersections, since
intersections are the most
likely places for scooter
accidents to occur.
9Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.8Many 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.
9Make sure that you are quali-
fied and that you only lend your
scooter to other qualified
operators.
9Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
9We 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 operator
is veering wide on a turn due to
EXCESSIVE SPEED or
undercornering (insufficient lean
angle for the speed).
9Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
