SAFETY INFORMATION
EAU10269
Be a Responsible Owner
As the vehicle’s owner, you are re-
sponsible for the safe and proper op-
eration of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements be-
fore riding this scooter.
He or she should:● Obtain thorough instructions from
a competent source on all as-
pects of scooter operation.● Observe the warnings and main-
tenance requirements in this
Owner’s Manual.● Obtain qualified training in safe
and proper riding techniques.● Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made nec-
essary by mechanical conditions.
Safe Riding
Perform the pre-operation checks
each time you use the vehicle to make sure it is in safe operating condition.
Failure to inspect or maintain the ve-
hicle properly increases the possibility
of an accident or equipment damage.
See page 4-2 for a list of pre-opera-
tion checks.
● This scooter is designed to carry
the operator and a passenger.● The failure of motorists to detect
and recognize scooters in traf-
fic is the predominating cause
of automobile/scooter accidents.
Many accidents have been
caused by an automobile driver
who did not see the scooter. Mak-
ing yourself conspicuous appears
to be very effective in reducing
the chance of this type of acci-
dent.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, since in-
tersections 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 inexpe-
rienced operators. In fact, many
operators who have been in-
volved in accidents do not even
have a current driver’s license.
• Make sure that you are quali-
fi ed and that you only lend your
scooter to other qualified op-
erators.
• 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 traffi c 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).
