SAFETY INFORMATION
EAU10264
Be a Responsible Owner
As the vehicle’s owner, you are respon-
sible for the safe and proper operation
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 before
riding this scooter.
He or she should:

Obtain thorough instructions from
a competent source on all aspects
of scooter operation.

Observe the warnings and mainte-
nance requirements in this Own-
er’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 neces-
sary 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 vehicle properly
increases the possibility of an accident
or equipment damage. See page 4-1
for a list of pre-operation checks.

This scooter is designed to carry
the operator and a passenger.

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 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 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 operator. A
typical error made by the operator
is veering wide on a turn due to ex-
cessive speed or undercornering
(insufficient lean angle for the
speed).
