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.
EBU00538
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.

Shifting
This model has a 6-speed forward and 1-speed
reverse transmission. The transmission allows
you to control the amount of power you have
available at a given speed or for starting, accel-
erating, climbing hills, etc. To shift into neutral,
return the throttle lever to its original 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 neu-
tral.
CAUTION:

1. 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.
2. Always use the clutch when changing
gears. The engine, transmission and driv-
etrain are not designed to withstand the
shock of forced shifting and can be dam-
aged by shifting without the clutch.

To start out and accelerate:
1. Release the throttle lever.
CAUTION:

Always close the throttle while 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.
5. Once the machine has attained adequate
speed, release the throttle, and at the
same time, quickly pull in the clutch lever.

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. Improp-
er use of the brakes or shifting can cause the
tires to lose traction, reducing control and in-
creasing the possibility of an accident.
WARNING
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 in-
jury. It could also cause engine or drive traindamage.

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. Dur-
ing the first 20 hours, the various parts in the
engine wear and polish themselves to the cor-
rect operating clearances.
During this period, prolonged full throttle oper-
ation or any condition which might result in ex-
cessive engine heating must be avoided.
However, momentary (2 ~ 3 seconds maxi-
mum) full throttle operation under load does
not harm the engine.
Each full throttle acceleration sequence should
be followed with a substantial rest period for
the engine by cruising at lower r/min so the en-
gine can rid itself of the temporary build up of
heat.
If any abnormality is noticed during this peri-
od, consult a Yamaha dealer.

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 sosteep you could not walk up them easily.
1. Bring the machine to a stop by applying
the brakes in low gear.
2. Stop the engine and release the clutch le-
ver.
3. With the front and rear brakes applied, ap-
ply the parking brake and slowly release
the rear brake pedal.

Riding your machine requires skills acquired
through practice over a period of time.
Take the time to learn the basic techniques well
before attempting more difficult maneuvers.
Not recommended for children under 16 years
of age.
WARNING

A child under 16 should never operate an ATV
with engine size greater than 90cc. Use by
children of ATVs that are not recommended
for their age can lead to severe injury or death
of the child.
