SAFETY INFORMATION
EAUT1018
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.
●
Never operate a scooter without
proper training or instruction. Take
a training course. Beginners
should receive training from a cer-
tified instructor. Contact an autho-
rized scooter dealer to find out
about the training courses nearest
you.
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.
TIPAlthough 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 auto-
mobile/scooter accidents. Many
accidents have been caused by anautomobile 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.
Never maintain a scooter with-
out proper knowledge. Contact
an authorized scooter dealer to
inform you on basic scooter
maintenance. Certain mainte-
nance can only be carried out by
certified staff.

extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
