CAUTION:_ Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system. _
WARNING
_

Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.


Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up any
spilled fuel immediately.


Do not refuel right after the engine has
been running and is still very hot.


Be sure the fuel tank cap is closed secure-
ly.

Ride more slowly than you would without a
load. The more weight you carry, the slower
you should go. Although conditions vary, it is
good practice not to exceed low range whenev-
er you are carrying heavier loads or when tow-
ing a trailer.


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.WARNING
_ Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
vehicle handling which could lead to an acci-
dent. Cargo should be properly distributed and
securely attached. Reduce speed when carry-
ing cargo or pulling a trailer. Allow greater dis-
tance for braking. _

RIDE WITH CARE AND GOOD JUDGEMENT
Get training if you are inexperienced.
Beginners should get training from a certified in-
structor.
Become familiar with this ATV at slow speeds first,
even if you are an experienced operator. Do not
attempt to operate at maximum performance until
you are totally familiar with the ATV’s handling and
performance characteristics.
WARNING
_ Never operate this ATV without proper instruc-
tion. Beginning and inexperienced operators
should regularly practice the skills and the op-
erating techniques described in this Owner’s
Manual. The risk of an accident is greatly in-
creased if the operator does not know how to
operate the ATV properly in different situations
and on different types of terrain. _
