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.
w
8Always 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.
8Always 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.

Starting a cold engine
w
Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or
do not work smoothly, you could be unable
to control the ATV, which could lead to an
accident or collision.
1. Set the parking brake.
2. Turn the fuel cock to “ON”.
3. Turn the main switch to “ON” and the
engine stop switch to “RUN”.
4. Shift the transmission into neutral.

Parking on a slope
w
Avoid parking on hills or other inclines.
Parking on a hill or other incline could cause
the ATV to roll out of control, increasing the
chance of an accident. If you must park on
an incline, put the ATV in low gear, apply the
parking brake, and block the front and rear
wheels with rocks or other objects.
Do not park the ATV at all on hills that are so
steep you could not walk up them easily.
1. Bring the machine to a stop by applying
the brakes in low gear.
2. Stop the engine.
3. With the rear brake lever and pedal
applied, apply the parking brake and slowly
release the rear brake pedal.

Select a large, flat area off-road to become
familiar with your ATV. Make sure that this area
is free of obstacles and other riders. You should
practice control of the throttle, brakes, shifting
procedures, and turning techniques in this area
before trying more difficult terrain. Always avoid
riding on paved surfaces: the ATV is designed
for off-road use only, and handling maneuvers
are more difficult to perform on pavement.
Set the parking brake and follow the instruction
on page 6-3 to start the engine. Once it has
warmed up you are ready to begin riding your
ATV. As you get on the ATV, be sure not to
accidentally move the shift pedal. Remember
that the engine and exhaust pipe will be hot
when riding and afterwards; do not allow skin or
clothing to come in contact with these compo-
nents.
