SAFETY INFORMATION
1ed 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 is im-
portant for proper control. The op-
erator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the scooter.

Do not place magnets or objects
with a strong magnetic force near
the accelerator grip. In addition, do
not place objects susceptible to
magnetic forces (i.e., credit cards,
watches, etc.) close to the acceler-
ator grip.

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.
Avoid submerged roads
Do not ride on flooded roads. Water
could cause power unit failure, electric
leakage, and/or short-circuiting.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 that 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.

Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust sys-
tem become very hot during or af-
ter operation and can cause burns.
Loading
Adding accessories or cargo to your
scooter can adversely affect stabilityand 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, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your scooter:
The total weight of the operator, acces-
sories and cargo must not exceed the
maximum load limit. Operation of an
overloaded vehicle could cause an
accident.
When loading within this weight limit,
keep the following in mind:

Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos-
sible and make sure to distribute
the weight as evenly as possible
on both sides of the scooter to min-Maximum load:

SAFETY INFORMATION
1passing or being passed by
large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.

Use caution when adding electri-
cal accessories. If electrical acces-
sories exceed the capacity of the
scooter’s electrical system, an
electric failure could result, which
could cause a dangerous loss of
lights or motor power.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, siz-
es, and combinations may not be
appropriate. Refer to page 8-5 for tire
specifications and more information on
replacing your tires.Transporting the Scooter
Be sure to observe following instruc-
tions before transporting the scooter in
another vehicle.

Remove all loose items from the
scooter.

Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.

Secure the scooter with tie-downs
or suitable straps that are attached
to solid parts of the scooter, such
as the frame or upper front fork tri-
ple clamp (and not, for example, to
rubber-mounted handlebars or
turn signals, or parts that could
break). Choose the location for the
straps carefully so the straps will
not rub against painted surfaces
during transport.

The suspension should be com-
pressed somewhat by the
tie-downs, if possible, so that the
scooter will not bounce excessive-
ly during transport.
EAUT2030
Further safe-riding points 
Make sure to signal clearly when
making turns.

Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.

Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.

Be careful when passing parked
cars. A driver might not see you
and open a door in your path.

Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.

The brake lining could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

Always wear a helmet, gloves,
trousers (tapered around the cuff
