SCOOTER SAFETY

IMPORTANT SAFETY INFORMATION

Your scooter can provide you many years of
service and pleasure if you take responsibility for
your own safety and understand the challenges
that you can meet on the road. There is much that
you can do to protect yourself when you ride. You
will find many helpful recommendations
throughout this manual. Here are some very
important safety tips:

Wear a helmet

Scooter safety equipment starts with a quality
helmet. One of the most serious injuries you can
suffer in a crash is a head injury. Always wear a
properly approved helmet. You should also wear
suitable eye protection.

Make yourself easy to see

To make yourself more visible, wear bright
reflective clothing, position yourself so other
drivers can see you, signal before turning or
changing lanes, and use your horn when it will help
others notice you.

Know your limits

Ride within the boundaries of your own skill at all
times. Knowing these limits and staying within
them will help you to avoid accidents.

2

Keep your scooter in safe condition

For safe riding, it's important to inspect your
scooter before every ride and perform all
recommended maintenance. Never exceed load
limits, and only use accessories that have been
approved by KYMCO for this scooter.

Inspect your scooter before riding

Do not forget to perform an entire safety inspection
to ensure you, and your passenger's safety, before
each ride.

Be extra safety conscious on bad
weather days

Riding on bad weather days, especially wet ones,
requires extra caution. Braking distance can
double on a rainy day. Stay off of the painted
surfaces, manhole covers and greasy appearing
areas on the pavement, as they can be especially
slippery. Use extreme caution at railway crossings
and on metal gratings and bridges. Whenever you
are in doubt about the road conditions, slow down.

Modification

Modification of your scooter, or removal of original
equipment may render the vehicle unsafe or illegal.
Obey all applicable equipment regulations in your
area.

SCOOTER SAFETY

PROTECTIVE APPAREL

For your safety, always wear an approved
motorcycle or scooter helmet, eye protection,
boots, gloves, long pants, and a long- sleeved shirt
or jacket whenever you ride your scooter.

Helmets and protection

Your helmet is your most important piece of riding
gear because it offers the best protection against
head injuries. Your helmet should fit your head
comfortably and securely. Always wear a face
shield or goggles to protect your eyes and to aid
your vision.

Additional riding gear

In addition to a helmet and eye protection, you
should also use:

Sturdy boots with nonslip soles to help protect your
feet and ankles.
Leather gloves to keep your hands warm and help
prevent blisters, cuts, burns and bruises.
A motorcycle or scooter riding suit or jacket that has
been designed for comfort as well as protection.
Bright colored and reflective clothing can help make
you more noticeable in traffic. Be sure to avoid loose
clothes that could get caught on any part of your
scooter.

1

Wear gloves
Clothes should be fit properly (not too tight or

2

loose)

3

Always wear a helmet. You should also wear
eye protection

4

Wear bright or reflective clothing
Footwear should be the proper size, have low

5

heels, and offer ankle protection

WARNING

Not wearing a helmet increases your
chance of serious injury or death in a
crash.

WARNING

Be sure you and your passenger always
wear an approved motorcycle helmet
that fits properly. You should also wear
eye protection and other protective
apparel when you ride.

SECTION 4 ­MAINTENANCE

The importance of maintenance

Maintaining your scooter properly is essential for
safe, economical and trouble-free riding. It will also
help reduce air pollution and maximize fuel
economy.

To help you properly care for your scooter, the
following pages in this Owner's Manual include a
maintenance schedule to help you make sure your
scooter is serviced at the appropriate intervals.

These instructions are based on the assumption
that your scooter will be used exclusively for its
designed purpose. Sustained high speed
operation or operation in unusually wet or dusty
conditions will require more frequent service than
specified in the maintenance schedule. Consult
your KYMCO dealer for recommendations
applicable to your individual needs and use.

NOTE: Always follow the inspection and
maintenance recommendations and schedules in
this Owner's Manual.

WARNING

If your scooter tips over or becomes involved in a
crash, be sure your KYMCO dealer inspects all
major parts, even if you are able to make some
repairs.

Improperly maintaining this scooter or failing to
correct a problem before you ride could result in
a crash in which you could be seriously hurt or
killed.

WARNING

When performing maintenance on your scooter
you may need to start the engine. Running your
scooter's engine indoors or in a garage can be
hazardous. Exhaust gas contains carbon
monoxide, a gas that is colorless and odorless,
and can cause death or severe injury.
Operate the engine only where these is
adequate ventilation, preferably outdoors.

Spark plug

MAINTENANCE

Remove the carbon deposits from the spark plug
with a small wire brush or a spark plug cleaning
machine. After cleaning (or when installing a new
spark plug) readjust the spark plug gap to specified
limit by using a spark plug gap thickness gauge.
The spark plug should be replaced periodically.

Whenever removing the carbon deposits, be sure
to observe the color of the removed spark plug's
porcelain tip. This color tells you whether or not the
standard spark plug is suitable for your type of
riding. Under normal usage, a spark plug's
porcelain tip should be light brown or tan color.

If the spark plug porcelain tip is very white or
glazed appearing, then the spark plug has been
operating too hot. In such a situation, you should
replace the standard spark plug with a spark plug
that has a colder heat range (usually a higher
number; consult with your KYMCO dealer when
selecting an alternate spark plug).

Recommended spark plug CR7E

CAUTION

An improper spark plug may have an incorrect fit
or heat range for your engine. This may cause
severe engine damage which will not be covered
under warranty. Never use a spark plug with an
improper heat range, as severe engine damage
could result.

MAINTENANCE

Brake fluid

Brake fluid level inspection

With the scooter in an upright position, check the
front and rear fluid level.

The level should be above the lower level mark. If
the level is at or below the lower level mark
"LOWER”, check the brake pads for wear.

NOTE: Other checks - make sure there are no
fluid leaks. Check for deterioration or cracks in the
hoses and fittings.

WARNING

Worn brake pads should be replaced
immediately. If the pads are not worn, have your
brake system inspected for leaks. Do not ride
your scooter unless the brakes are in perfect
working order.

Brake fluid type: DOT 4

MAINTENANCE

Brake inspection

Your scooter requires the proper brake lever free­play so the brakes will be responsive and will not
drag, causing premature wear to the brake pads.

The free-play is the measured distance between
the brake lever at rest and a fully applied brake.

Measure the free-play and the brake lever end

1.

0.4 - 0.6 in (10 - 20 mm).

Use the cable adjuster on rear brake lever perch

2.
for minor free play adjustment.

To perform free play adjustment outside of the

3.
range of the cable adjusters on the brake lever
perches, use the adjuster nut at the end of the
brake cable where it connects to the brake arm.

NOTE: Before adjusting the free play with the
brake arm adjuster nut, turn the adjusters on the
brake lever perches as far as they will turn in a
clockwise direction.

0.4 -0.6 in (10-20 mm)

Rotating the adjuster nut clockwise reduces

4.
the clutch lever free play. Rotating the adjuster
nut counterclockwise increases the clutch
lever play.

MAINTENANCE

WARNING

For appropriate brake action, make sure the
groove of the adjusting nut is aligned with the pin
in the brake arm.

Inspect the brake pad and shoe thickness to verify
there is enough material for the brakes to function
properly.

If the wear indicator grooves in the front brake

1.
pads are no longer visible , it is an indication
that the brake pads are worn and require
replacement.

If the wear indicator grooves in the rear brake

2.
pads are no longer visible , it is an indication

that the brake pads are worn and require
replacement.

WARNING

The brakes will wear quickly if the lever is
continually applied during riding (dragging the
brake).
Consult your KYMCO dealer for braking system
service.

MAINTENANCE

Battery

Your KYMCO scooter is equipped with a
maintenance-free (sealed) type battery so it is not
necessary to check the battery's electrolyte level or
add distilled water.

NOTE: If your battery seems weak and/or is
leaking electrolyte (causing hard starting or other
electrical troubles), contact your KYMCO dealer
immediately.

CAUTION

Your battery is a maintenance-free type and can
be permanently damaged if the cap strip is
removed.

Fuse

When frequent fuse failures occur, it usually
indicates a short circuit or an overload in the
electrical system.

NOTE: See your KYMCO dealer for electrical

system diagnosis and repair.

WARNING

Never use a fuse with a different rating from that
specified. Serious damage to the electrical
system or a fire may result, causing a dangerous
loss of lights or engine power.

MAINTENANCE

Tires

WARNING

Failure to follow these warnings may result in an
accident due to tire failure. The tires on your scooter
are a crucial link between your scooter and the road.
You and your passenger's personal safety are
dependant upon the condition of your scooter'stires.
Follow these instructions:

Check tire condition and pressure, and adjust the
inflation pressure before each ride.

Avoid overloading yourscooter.

Replace a tire when worn to the specified limit, or if you
find any damage such as cuts orcracks.

Always use the proper size and type of tires as
specified in this Owner's Manual.

Balance the wheel after tire installation.

Read this section of Owner's Manual carefully.

Failure to perform a reasonable break-in of the tires
could cause tire slip and lossof control.
Use extra care when riding on new tires as the grip
will be limited. Perform proper break-in of the tires, as
stated in the break-in recommendation section of this
manual. Avoid hard acceleration, hard cornering, and
hard braking for the first 100miles (160 km).

NOTE: Check the tire inflation pressure and tire
tread condition at the periods listed in the periodic
maintenance schedule. For maximum safety and
good tire life, the tire pressures should be
inspected more often.

Tire pressure

Insufficient air pressure in the tires not only
accelerates tire wear but it also affects the stability
of your scooter. Under-inflated tires make smooth
cornering difficult and overinflated tires decrease
the amount of tire in contact with the ground, which
can lead to skids and loss of control. Make sure
that the tire pressures on your scooter are within
the specified limits at all times.

NOTE: Tire pressure should only be adjusted

when the tires are cold.

Front tire (rideronly): 21.3 PSI (1.5kgf/cm )

Rear tire (rider only): 28.4 PSI (2.0 kgf/cm )

Front tire (rider& passenger):24.9 PSI (1.75kgf/cm )

Rear tire (rider & passenger): 32.0 PSI(2.25 kgf/cm )
