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 control 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.

9. Install the foam cover onto the air filter ele-
ment.
10. Install the air filter assembly and parts re-
moved for access.NOTE:The air filter element should be cleaned every 20–
40 hours. It should be cleaned more often if the
machine is operated in extremely dusty areas.
Each time filter element maintenance is per-
formed, check the air inlet to the filter case for ob-
structions. Check the air cleaner rubber joint to the
carburetor and manifold fittings for an airtight seal.
Tighten all fittings securely to avoid the possibility
of unfiltered air entering the engine. CAUTION:
Never operate the engine with the air filter ele-
ment removed. This will allow unfiltered air to
enter, causing rapid engine wear and possible
engine damage. Additionally, operation with-
out the filter element will affect carburetor jet-
ting with subsequent poor performance and
possible engine overheating.
