4. Brake operation
Test the brakes at slow speed after start-
ing out to make sure they are working
properly. If the brakes do not provide
proper braking performance, inspect the
brake pads for wear. (See page 8-89.)
WARNING

Always check the brakes at the start of every
ride. Do not ride the ATV if you find any prob-
lem with the brakes or you could lose braking
ability, which could lead to an accident. If a
problem cannot be corrected by the adjust-
ment procedures provided in this manual,
have the ATV inspected by a Yamaha dealer.

Parking on a slope
WARNING
Avoid parking on hills or other inclines. Park-
ing 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, place the machine transversely across
the incline, 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 easi-ly.
1. Bring the machine to a stop by applying
the brakes.
2. Stop the engine.
3. With the rear brake applied, shift the drive
select lever to the park position.

Select a large, flat area off-road to become fa-
miliar 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. Al-
ways 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 instruc-
tion 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 ac-
cidentally 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 com-
ponents.
