(choke) in this position to warm up the en-
gine.
8. Continue warming up the engine until it idles
smoothly and return the starter (choke) to po-

Starting a warm engine
To start a warm engine, refer to the “Starting a cold
engine” section. The starter (choke) should not be
used. The throttle should be opened slightly.
EBU01820
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 en-
gine is warm, check if it responds to the throttle
normally with the starter (choke) turned off.

Shifting
This model has a 6-speed forward and 1-speed re-
verse transmission. The transmission allows you
to control the amount of power you have available
at a given speed or for starting, accelerating,
climbing hills, etc. To shift into neutral, return the
throttle lever to the closed position, apply the
clutch and repeatedly depress the shift pedal until
it stops. When it stops, it will be in first gear. Raise
the pedal slightly to neutral.CAUTION:_

Do not coast for long periods with the en-
gine off, and do not tow the machine a
long distance. Even in neutral position,
the transmission is only properly lubricat-
ed when the engine is running. Inade-
quate lubrication may cause damage.


Always use the clutch when changing
gears. The engine, transmission and drive
train are not designed to withstand the
shock of forced shifting and can be dam-
aged by shifting without the clutch.

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.

Engine break-in
There is never a more important period in the life of
your machine than the period between zero and
20 hours.
For this reason, we ask that you carefully read the
following material. Because the engine is brand
new, you must not put an excessive load on it for
the first several hours of running. During the first
20 hours, the various parts in the engine wear and
polish themselves to the correct operating clear-
ances.
During this period, prolonged full throttle operation
or any condition which might result in excessive
engine heating must be avoided. However, mo-
mentary (2–3 seconds maximum) full throttle oper-
ation under load does not harm the engine.
Each full throttle acceleration sequence should be
followed with a substantial rest period for the en-
gine by cruising at lower r/min so the engine can
rid itself of the temporary build up of heat.
If any abnormality is noticed during this period,
consult a Yamaha dealer.

Parking
When parking, stop the engine and shift into neu-
tral. Turn the fuel cock to “OFF” and apply the
parking brake.
EBU14740
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 machine in low gear, 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 easily. _
