Be a Responsible Owner
As the vehicle’s owner, you are res-
ponsible for the safe and proper ope-
ration of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are
dependent upon the use of proper
riding techniques as well as the
expertise of the operator. Every ope-
rator should know the following requi-
rements 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 main-
tenance requirements in this
Owner’s Manual.
●Obtain qualified training in safe
and proper riding techniques.
●Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary by mechanical
conditions.Safe Riding
Perform the pre-operation checks
each time you use the vehicle to
make sure it is in safe operating con-
dition. Failure to inspect or maintain
the vehicle properly increases the
possibility of an accident or equip-
ment 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
automobile/scooter accidents.
Many accidents have been cau-
sed by an automobile driver who
did not see the scooter. Making
yourself conspicuous appears to
be very effective 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
intersections are the most
likely places for scooter acci-
dents to occur.• Ride where other motorists can
see you. Avoid riding in anot-
her motorist’s blind spot.
●Many accidents involve inexpe-
rienced operators. In fact, many
operators who have been invol-
ved in accidents do not even
have a current driver’s license.
• Make sure that you are quali-
fied and that you only lend your
scooter to other qualified ope-
rators.
• 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
controls.
●Many accidents have been cau-
sed by error of the scooter ope-
rator. A typical error made by the
operator is veering wide on a turn
due to excessive speed or under-
cornering (insufficient lean angle
for the speed).

Fuel
Make sure there is sufficient gasoline
in the tank.
EWA10881

WARNING
Gasoline and gasoline vapors are
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 engi-
ne and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the
vicinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank
filler hole. Stop filling when the
fuel reaches the bottom of the
filler tube. Because fuel expands
when it heats up, heat from the
engine or the sun can cause fuel
to spill out of the fuel tank.

2. Fuel level
3. Wipe up any spilled fuel imme-
diately. NOTICE: Immediately
wipe off spilled fuel with a cle-
an, dry, soft cloth, since fuel
may deteriorate painted surfa-
ces or plastic parts.

4. Be sure to securely close the fuel
tank cap.

WARNING
The exhaust system is hot after
operation. To prevent a fire hazard
or burns:
●Do not park the vehicle near
possible fire hazards such as
