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

To start out and accelerate:
1. Release the throttle lever.
cC
Always close the throttle before shifting the
transmission into the drive position.
Otherwise, damage to the engine and drive
train may result.
2. Apply the parking brake. (See page 6-23.)
3. Shift the transmission into the drive posi-
tion.
NOTE:
Before shifting the transmission into the drive
position, be sure to apply the parking brake. The
engine will stop if you attempt to shift into drive
without applying the parking brake first.

4. Squeeze the rear brake lever to release
the parking brake.

slowly releasing the rear brake lever.

Always open the throttle gradually. Opening
the throttle abruptly would increase the
chance of an accident. It could make the
machine wheelie or overturn.

To decelerate:
When slowing down or stopping, release the
throttle 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 shifting can cause the tires to lose
traction, reducing control and increasing the
possibility of an accident.
w
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a
lower 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.
