Your KYMCO engine has been designed to use
regular unleaded gasoline with a pump octane
number of 86 or higher, or research octane
number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or
premium unleaded fuel. Unleaded fuel will give
you longer spark plug life and reduced
maintenance cost.
Use unleaded fuel only because it produces
fewer engine and spark plug deposits and
extends the life of the exhaust system. Never
use stale or contaminated gasoline or an
oil/gasoline mixture.
Avoid getting dirt, dust or water in the fuel tank.
WARNING
POTENTIAL HAZARD
Improper care when refueling.
WHAT CAN HAPPEN
Fuel can spill, which can cause a fire and
severe injury.
Fuel expands when it heats up. If the fuel
tank is overfilled, fuel could spill out due to
heat from the engine.
HOW TO AVOID THE HAZARD
Do not overfill the fuel tank. Be careful not
to spill fuel, especially on the engine or
exhaust pipe. Wipe up any spilled fuel
immediately. Be sure the fuel tank cap is
closed securely.
Do not refuel right after the engine has
been running and is still very hot.

COOLANT (MXU 250)
Check the coolant level in the reservoir tank
when the engine is cold. (The coolant level
will vary with engine temperature.) The
coolant level is satisfactory if it is between the
"FULL" and "LOW" marks on the tank. If the
coolant level is at or below the "LOW" level,
add tap water (soft water) to bring the level up
to "FULL". Change the coolant every two
years. (See page 159~160 for details.)
CAUTION:
Hard water or salt water is harmful to the
engine. You may use distilled water if rou

ENGINE BREAK-IN
There is never a more important period in the life
of your machine than the period between zero
and 20 hours.
For this reason, we ask that you carefully read
the following material. Because the engine is
brand new, you must not put an excessive load
on it for the first 20 hours, the various parts in
the engine wear and polish themselves to the
correct operating clearances.
During this period, prolonged full throttle
operation or any condition which might result in
excessive engine heating must be avoided.
However, momentary (2~3 seconds maximum)
full throttle operation under load does not harm
the engine.
Each full throttle acceleration sequence should
be followed with a substantial rest period for the
engine by cruising at lower r/min so the engine
can rid itself of the temporary build up of heat.
If any abnormality is noticed during this period,
consult a KYMCO dealer.
1. 0~10 hours:
Avoid continuous operation above half
throttle. Allow a cooling off period of five to
ten minutes after every hour of operation.
Vary the speed of the machine from time to
time. Do not operate it at full throttle position.
2. 10~20 hours:
Avoid prolonged operation above 3/4 throttle.
Rev the machine freely through the gears but
do not use full throttle at any time.
3. After break-in
Avoid prolonged full throttle operation. Vary
speeds occasionally.

Parking on a slope
WARNING
POTENTIAL HAZARD
Parking on a slope or other incline.
WHAT CAN HAPPEN
The ATV could roll out of control, increasing
the chance of an accident.
HOW TO AVOID THE HAZARD
Avoid parking on slope or other inclines. If
you must park on an incline, place the
machine transversely across the incline,
apply the parking brake, and block the front
and rear wheels with rocks or other objects.
Do not park the ATV at all on slope that are
so steep you could not walk up them easily.

ACCESSORIES
Accessories can affect the handling and control
of your ATV. Keep the following in mind when
considering an accessory or operating an ATV
which has accessories.
Choose only accessories designed for your
ATV. Your KYMCO dealer has a variety of
genuine KYMCO accessories. Other
accessories may also be available on the
market. However, it is not possible for KYMCO
to test all non-KYMCO accessories, nor have
any control over the quality or suitability of
them. Choose a genuine KYMCO accessory,
or one that is equivalent in design and quality.
Accessories should be rigidly and securely
mounted. An accessory which can shift
position or come off while you are riding could
affect your ability to control the ATV.
Do not mount an accessory where it could
interfere with your ability your to control the
ATV. Examples include (but are not limited to)
a heavy or bulky object attached to the
handlebars which could make steering
difficult, an accessory that limits your ability
to move around on the seat, or one that limits
your view.
Use extra caution when riding an ATV with
accessories. The ATV may handle differently
than it does without accessories.

center of the vehicle as possible. Put cargo at
the rear of the front and at the front
of the rear . Center the load from
side to side.
Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around.
A shifting load can cause an accident.
Make sure the load does not interfere with
controls or your ability to see where you are
going.
Ride more slowly than you would without a
load. The more weight you carry, the slower
you should go.
Allow more braking distance. A heavier
vehicle takes longer to stop.
Avoid making sharp turns unless at very slow
speeds.
Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability
and handling of the ATV.
Never carry passenger on the cargo racks.
