Front and rear brakes
Brake levers and brake pedal

Check for correct free play in the front brake le-
ver. If the free play is incorrect, have a Yamaha
dealer adjust it.


Check for correct free play in the rear brake le-
ver and brake pedal. If the free play is incorrect,
adjust it. (See pages 8-65–8-71.)


Check the operation of the brake levers and
pedal. They should move smoothly and there
should be a firm feeling when the brakes are
applied. If not, have a Yamaha dealer inspect
the brake system.
Brake fluid level (front brake)
Check the brake fluid level. Add fluid if necessary.
(See pages 8-59–8-61.)

Brake fluid leakage (front brake)
Check to see if any brake fluid is leaking out of the
hose, joint or brake fluid reservoir of the front
brake. Apply the brake firmly for one minute. If the
lever moves slowly inward, there may be a leak in
the brake system. If there is any leakage, the
brake system should be inspected by a Yamaha
dealer.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance, in-
spect the brake pads and shoes for wear. (See
pages 8-55–8-57.)
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 a Yamaha dealer check for the cause. _

To decelerate:
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure that
the engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shift-
ing can cause the tires to lose traction, reducing
control and increasing the possibility of an acci-
dent.
WARNING
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a low-
er gear when the engine speed is too high
could make the wheels stop rotating. This
could cause loss of control, an accident and
injury. It could also cause engine or drive train
damage.

low a cooling off period of five to ten minutes after
every hour of operation. Vary the speed of the ma-
chine from time to time. Do not operate it at one
set throttle position.
10–20 hours:
Avoid prolonged operation above 3/4 throttle. Rev
the machine freely through the gears but do not
use full throttle at any time.
After break-in:

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, put the ATV in low gear, apply the park-
ing 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 ATV to a stop by applying the
brakes in low gear.
2. Stop the engine.
3. With the rear brake lever and brake pedal ap-
plied, apply the parking brake and slowly re-
lease the brake pedal.
