Always check for obstacles before operating in
a new area.


Never attempt to operate over large obstacles,
such as large rocks or fallen trees. Always fol-
low proper procedures when operating over
obstacles as described in this manual.


Always be careful when skidding or sliding.
Learn to safely control skidding or sliding by
practicing at low speeds and on level, smooth
terrain. On extremely slippery surfaces, such
as ice, go slowly and be very cautious in order
to reduce the chance of skidding or sliding out
of control.


Never operate an ATV in fast flowing water or
in water deeper than that recommended in this
manual. Remember that wet brakes may have
reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several
times to let friction dry out the linings.

Parking brake
Use the parking brake when you have to start the
engine or park the machine, especially on a slope.
Apply the rear brake lever and push down the lock
plate to apply the parking brake. Squeeze the rear
brake lever to release the parking brake.
WARNING
_

Always set the parking brake before start-
ing the engine. The ATV could start mov-
ing unexpectedly if the parking brake is
not applied. This could cause loss of con-
trol or a collision.


Always be sure you have released the
parking brake before you begin to ride.
The brake could overheat if you ride the
ATV without releasing the parking brake.
You could lose braking performance
which could cause an accident. You could
also wear out the brakes prematurely.
