Important Safety Information
Understand the challenges that you will face when operating a scooter will greatly improve your safety on the roads. There ar e
many things that you can do to protect yourself when riding. You will find many helpful recommendations throughout this
manual. Following are few that we consider most important.
Always Wear Protective Gears
It is a proven fact: helmets significantly reduce the number and severity of head injuries. Always wear helmets, eye protection,
sturdy boots, gloves, and other protective gears when riding.
Make Yourself Visible
Some drivers do not see scooters because they do not look for them. To make yourself more visible:
• Wear bright reflective clothing while riding.
• Position yourself in the traffic lane so other drivers can see you.
• Signal before turning or changing lanes.
• Use your horn to alert others on the road.
• Always use headlights while riding, even during daytime.
SAFETY INFORMATION
- 1 -
Ride Within Your Limit
Pushing the limits is a common cause of scooter accidents. Never ride beyond your personal abilities or faster than conditions
warrant. Remember that alcohol, drugs, fatigue and inattention can significantly reduce your ability to make good judgments and
ride safely.
Keep Your Scooter In Safe Condition
For safe riding, it is important to inspect your scooter before every ride, and perform recommended maintenance in a timely
manner.
Loading Limit Guidelines
Your scooter has been designed to carry you and one passenger. When you carry a passenger, you may notice some changes in
acceleration and braking. However, as long as you keep your scooter well maintained, with good brakes, you can safely carry
loads within manufacturer’s recommended weight limit. Exceeding the weight limit or carrying an unbalanced load can
seriously affect your scooter’s handling, braking, and stability. Improper modifications and poor maintenance can also reduce
your safety.

To ensure maximum performance, longer durability, and
safe operation, always check and adjust the tire pressure
before operating your scooter.
NOTE:
*Tire pressure should be checked and adjusted when tire
temperature equals the ambient air temperature. Tire
pressure must be adjusted according to the total weight
of cargo, rider, passenger, accessories, and vehicle speed.
Refer to tire walls for proper inflation pressure.
Tires
Make sure the total weight of the cargo, rider, passen-
ger, and accessories do not exceed the maximum
loading limit of your scooter. Operating overloaded
scooter could cause tire rupture, an accidents, and
injuries.
NOTE:
Proper loading affects several characteristics of
your scooter, such as handling, braking, accelera-
tion, and safety. Do not carry loosely packed items
that can shift during travel. Securely pack your
heaviest items close to the center of your scooter
and distribute the weight evenly from side to side.
Properly adjust the suspension to your load, and
check the condition and pressure of your tires.
Tire Inspection
Always check the tires before operating your scooter.
Contact a dealer if center tread depth reaches the limit as
show, if the tire has a nail or glass fragments in it, or if the
sidewall is cracked, and have the tire immediately replaced.

Periodic Maintenance and Minor Repair
Periodic inspection, adjustments, and lubrication will keep
your scooter in the safest and most efficient condition
possible. You must take into consideration that weather,
terrain, geographical locations, and a variety of causes all
tend to demand that each owner alter the time schedule for
regular maintenance to shorter intervals.
The most important points of scooter maintenance: inspec-
tion, adjustments, and lubrication are explained in the
following pages.
NOTE:
*If you are not familiar with servicing your scooter,
consult your local dealer. Your scooter is designed for
use on paved road surfaces only. If you operate the
scooter in abnormally dusty, muddy, or wet conditions,
the air filter should be cleaned or replaced more
frequently. Consult your local dealer for proper mainte-
nance intervals.

Spark Plug Inspection
The spark plug is an important engine compo-
nent. The condition of the spark plug can
indicate the condition of the engine. Therefore,
you should periodically inspect it for signs of
deterioration. The ideal color on the white insu-
lator around the center electrode is a medium to
light tan color for a scooter that is being ridden
normally.
Deposits will cause the spark plug to slowly
break down and erode. You should replace the
spark plug if electrode erosion becomes exces-
sive, or if carbon and other deposits become
excessive. Before installing the spark plug,
measure the electrode gap with a wire thickness
gauge. Adjust the gap to the specification.
Spark Plug Gap: 0.8mm
When installing the plug, always clean the
gasket surface. Wipe off any grime from the
threads. Tighten the spark plug with your fingers
first, then finish tightening with a wrench.
PERIODIC MAINTENANCE AND REPAIR
The front brake lever free play should be adjusted to 2-5mm
at the brake lever end.
The rear brake lever free play should be adjusted to 2-5mm
at the brake lever end.
Loosen the locknut and turn the adjusting bolt in direction A
to increase free play, in direction B to decrease free play. Be
sure to tighten the locknut after adjustments.
NOTE:
When it is not impossible to make the proper adjust-
ments on your own, consult your local dealer for profes-
sional guidance.
PERIODIC MAINTENANCE AND REPAIR
Brake Lever Free Play Adjustment Inspection of Brake Fluid Level
Insufficient brake fluid may allow air to enter the brake
system, possibly causing the brakes to become ineffective.
Before riding, check that the brake fluid is above the
minimum level and fill when necessary.
Observe These Precautions:
1. When checking the brake fluid level, make sure the top of
the master cylinder is leveled.
2. Use only the designated brake fluid. Otherwise, the rubber
seals may deteriorate, causing leakage and poor brake perfor-
mance. Recommended Brake Fluid: DOT3
3. Refill with the same type of brake fluid. Mixing fluid may
result in a harmful chemical reaction and lead to poor brake
performance.
4. Be careful that water does not enter, which may result in
vapor lock.
5. Brake fluid may deteriorate painted surfaces and plastic
parts. Always clean up the spilled fluid immediately.
6. Have a dealer check the cause if brake fluid level goes down.

Cable Inspection and Lubrication
NOTE:
*Damage to the outer housing of cables may allow
internal rusting and cause interference with cable move-
ment. Replace damaged cables as soon as possible to
prevent unsafe conditions.
Inspect the inner cable and the cable end. If it does not
operate smoothly, ask a dealer to replace them.
Front Fork Inspection
Securely support the scooter so there is no danger of it
falling over.
1. Visual Check:
Check for scratches or damage on the inner tube and exces-
sive oil leakage from the front fork.
2. Operation Check:
Place the scooter on a level place.
a. Hold the scooter in upright position and apply the front
brake.
b. Push down hard on the handlebars several times and
check if the fork rebounds smoothly.
NOTE:
*If any damage or jerky movement is found with the
front fork, consult your local dealer.

Steering Inspection
Periodically inspect the condition of the steering.
Worn out or loose steering bearings may be danger-
ous. Place a stand under the engine to raise the front
wheel off the ground. Hold the lower end of the front
forks and try to move them forward and backward. If
any free play can be felt, ask a dealer to inspect and
adjust the steering. Inspection is easier if the front
wheel is removed.
NOTE:
*Securely support the scooter so there is no danger
of it falling over.
Wheel Bearings
If there is play in the front or rear wheel hub or if the wheel
does not turn smoothly, have a dealer inspect the wheel
bearings.
PERIODIC MAINTENANCE AND REPAIR
Fuse Box
Fuse Replacement
If the fuse is blown, turn off the main switch and the switch of the circuit in
question. Remove the screws on battery case cover. The fuse is at the side
of the case. Install a new fuse of specified amperage. Make sure the new
fuse is fitted securely. Turn on the switches and see if the electrical device
operates.
Specified Fuse: 15A
NOTE:
*Do not use fuses of higher amperage rating than those specified.
Substitution of fuse of improper rating can cause extensive electrical
system damage and possibly a fire.
