SAFETY INFORMATION
• Always obey the speed limit
and never travel faster than
warranted by road and traffi c
conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
● The posture of the operator and
passenger is important for proper
control.
• The operator should keep both
hands on the handlebar and
both feet on the operator foot-
rests during operation to main-
tain control of the scooter.
• The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger foot-
rests. Never carry a passenger
unless he or she can fi rmly
place both feet on the passen-
ger footrests.● Never ride under the infl uence of
alcohol or other drugs.● This scooter is designed for on-
road use only. It is not suitable for off-road use.
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 pre-
vention 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
effective in preventing or reducing
abrasions or lacerations.● Never wear loose-fi tting 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
system become very hot during
or after operation and can cause
burns.
● A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause head-
aches, dizziness, drowsiness, nausea,
confusion, and eventually death.
Carbon Monoxide is a colorless,
odorless, tasteless gas which may
be present even if you do not see or
smell any engine exhaust. Deadly
levels of carbon monoxide can collect
rapidly and you can quickly be over-
come and unable to save yourself.
Also, deadly levels of carbon mon-
oxide can linger for hours or days in
enclosed or poorly ventilated areas.
If you experience any symptoms of
carbon monoxide poisoning, leave the
area immediately, get fresh air, and
SEEK MEDICAL TREATMENT.●
Do not run engine indoors. Even
if you try to ventilate engine ex-
haust with fans or open windows
and doors, carbon monoxide can
rapidly reach dangerous levels.

SAFETY INFORMATION
EAU10372
Further safe-riding points●
Be sure to signal clearly when
making turns.
ZAUM00**ZAUM00**●
Braking can be extremely diffi cult
on a wet road. Avoid hard brak-
ing, because the scooter could
slide. Apply the brakes slowly
when stopping on a wet surface.
●
Slow down as you approach a corner or turn. Once you have
completed 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 con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Slow down and
cross them with caution. Keep the
scooter upright, otherwise it could
slide out from under you.
●
The brake pads 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
and ankle so they do not fl ap),
and a bright colored jacket.
●
Do not carry too much luggage
on the scooter. An overloaded
scooter is unstable. Use a strong
cord to secure any luggage to
the carrier (if equipped). A loose
load will affect the stability of the bed, and choke it in a rail to pre-
vent movement.
●
Secure the scooter with tie-downs
or suitable straps that are at-
tached to solid parts of the scoot-
er, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted han-
dlebars 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 exces-
sively during transport.
