WARNING
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide, a deadly gas.
Breathing carbon monoxide can cause headaches,
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 overcome 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 exhaust with fans or open windows and doors,
carbon monoxide can rapidly reach dangerous levels.
● Do not run engine in poorly ventilated or partially en-
closed areas such as barns, garages, or carports.
● Do not run engine outdoors where engine exhaust can
be drawn into a building through openings such as wi-
ndows and Doors.
WARNING
When transporting the ATV in another vehicle, be sure it
is kept upright and that the fuel cock is in the “OFF”
position. Otherwise, fuel may leak out of the carburetor or
fuel tank.

Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.
Speed limiter
Your ATV is equipped with an adjustable speed limiter.
The speed limiter keeps the throttle from fully opening,
even when the throttle lever is pushed to maximum.

Fuel
Make sure there is sufficient gasoline in the tank.
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 engine and be sure that
no one is sitting 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 filter
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.
3. Wipe up any spilled fuel immediately.
NOTICE: Immediately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel may deteriorate
painted surfaces or plastic parts.
4. Turn the fuel tank cap fully clockwise to make sure it is
securely closed.
WARNING
Gasoline is poisonous and then cause injury or
death. Handle gasoline with care. Never siphon gasoline
by mouth. If you should swallow some gasoline or inhale
a lot of gasoline vapor, or get some gasoline in your
eyes, see your doctor immediately. If gasoline spills
on your skin, wash with soap and water. If gasoline
spills on your clothing, change your clothes.
NOTICE
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
