WARNING
EWB00220
Always set the parking brake before starting
the engine. The ATV could start moving un-
expectedly if the parking brake is not ap-
plied. This could cause loss of control or a
collision.
Always be sure you have released the park-
ing brake before you begin to ride. The brake
could overheat if you ride the ATV without re-
leasing the parking brake. You could lose
braking performance which could cause an
accident. You could also wear out the brakes
prematurely.EBU18530Shift pedal This ATV is equipped with a constant-mesh 6-
speed transmission. The shift pedal is located on
the left side of the engine and is used in combina-
tion with the clutch when shifting.
EBU18571Drive select lever The drive select lever is used for driving the ATV
either forward or in reverse. See the “Operating the
drive select lever and driving in reverse” section on
page 6-3 for the drive select lever operation.1. Shift pedal

understand, ask your Yamaha dealer.
WARNING
EWB00631Read the Owner’s Manual carefully to become
familiar with all controls in order to help pre-
vent any loss of control, which could cause an
accident or injury.EBU20162Starting a cold engine NOTICEECB00150See the “Engine break-in” section on page 6-6
prior to operating the engine for the first time.1. Set the parking brake.
2. Turn the fuel cock to “ON”.
3. Turn the key to “ON” and the engine stop
switch to“”.4. Shift the transmission into neutral. The neutral
indicator light should come on. If the indicator
light does not come on, have a Yamaha deal-
er check the electrical circuit.
TIPThis model is equipped with an ignition circuit cut-
off system. The engine can be started under the
following conditions.
The transmission is in neutral.
The clutch is disengaged with the shift pedal and
the drive select lever in any position. However, it
is recommended to shift into neutral before start-
ing the engine.5. Use the starter (choke) in reference to the fig-
ure:
Position (1):
Cold engine start with ambient temperature
below 5 °C (40 °F).
Position (2):
Cold engine start with ambient temperature
between 0 °C (30 °F) and 30 °C (90 °F).

EBU20591To start out and accelerate
1. Release the throttle lever, and then release
the parking brake.NOTICEECB00200Always close the throttle before shifting gears,
otherwise damage to the engine and drive train
may result.2. Pull the clutch lever to disengage the clutch.
3. Shift into first gear.
4. Open the throttle gradually and at the same
time, release the clutch lever slowly.
WARNING! Opening the throttle abruptly
or releasing the clutch lever too quickly
could make the ATV wheelie, which would
increase the chance of an accident, includ-
ing an overturn.
[EWB00731]
5. Once the ATV has attained adequate speed,
release the throttle, and at the same time,
quickly pull in the clutch lever.
6. Shift the transmission into second gear.
(Make sure not to shift the transmission into
neutral.)
7. Open the throttle part way and gradually re-
lease the clutch lever.8. Follow the same procedure when shifting to
the next higher gear.
EBU20650To 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 shifting
can cause the tires to lose traction, reducing con-
trol and increasing the possibility of an accident.
WARNING
EWB00710Make 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 and lose
traction. This could cause loss of control, an
accident and injury. It could also cause engine
or drive train damage.NOTICEECB00180
Even with the transmission in the neutral po-
sition, do not coast for long periods of time
with the engine off, and do not tow the ATV

engine, apply the parking brake, and then turn the
fuel cock to “OFF”.EBU20903Parking on a slope
WARNING
EWB00850Avoid parking on hills or other inclines. Park-
ing on a hill or other incline could cause the

chance of an accident. If you must park on an
incline, place the ATV transversely across theincline, shift into first gear, stop the engine, ap-
ply the parking brake, and then block the front
and rear wheels with rocks or other objects.

brake, shift into first gear, and then stop the
engine.
2. With the front and rear brakes applied, apply
the parking brake.
3. Release the front and rear brakes.
