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.

parking brake before you begin to ride.
The brake could overheat if you ride the
ATV without releasing the parking brake.

which could cause an accident. You could

Front and rear brakes
1. Brake lever and brake pedal
Check for correct free play in the front
brake lever. If the free play is incorrect, ad-
just it. Check for correct rear brake pedal
height. If the pedal height is incorrect,
have a Yamaha dealer adjust it. (See
pages 8-47 ~ 8-49.)
Check the operation of the lever and ped-
al. They should move smoothly and there
should be a firm feeling when the brakes
are applied. If not, have the machine in-
spected by a Yamaha dealer.
2. Brake fluid level

3. Brake fluid leakage
Check to see if any brake fluid is leaking
out of the pipe joints or master cylinders.
Apply the brakes firmly for one minute. If
there is any leaking, have the machine in-
spected by a Yamaha dealer.
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 8-39.)
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.

cold engine” section. The starter (choke)
should not be used. The throttle should be
opened slightly.

Warming up
To get maximum engine life, always warm up
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, check if it responds to the
throttle normally with the starter (choke)
turned off.NOTE:

When the parking brake is used, engine speed
is limited to 2,300 r/min. Be sure the parking
brake is released before moving the throttle le-
ver. Otherwise, the engine will misfire, pre-
venting normal operation.
