8. Continue warming up the engine until it idles
smoothly and return the starter (choke) to
position 3before riding.
cC
See the “Engine break-in” section prior to
operating engine for the first time.

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
lever. Otherwise, the engine will misfire, pre-
venting normal operation.

cC
1. Do not coast for long periods with the
engine off, and do not tow the machine a
long distance. Even in neutral position,
the transmission is only properly lubri-
cated when the engine is running. Inade-
quate lubrication may cause damage.
2. 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
damaged by shifting without the clutch.

To start out and accelerate
1. Release the throttle lever.
cC
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.
6. Shift into second gear. (be careful not to
shift into neutral)

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.

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 oper-
ating clearances.
During this period, prolonged full throttle opera-
tion or any condition which might result in exces-
sive engine heating must be avoided. However,
momentary (2–3 seconds maximum) full throttle
operation under load does not harm the engine.
5FK-9-64-6 4/8/02 1:22 PM Page 22

6-23
Each full throttle acceleration sequence should
be followed with a substantial rest period for the
engine 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.
1. 0–10 hours:
Avoid continuous operation above half throt-
tle. Allow a cooling off period of five to ten
minutes after every hour of operation. Vary
the speed of the machine from time to time.
Do not operate it at one set throttle position.
2. 10–20 hours:
Avoid prolonged operation above 3/4 throt-
tle. Rev the machine freely through the
gears but do not use full throttle at any time.
3. After break-in:
Avoid prolonged full throttle operation. Vary
speeds occasionally.

Parking
When parking, stop the engine and shift into low
gear. Turn the fuel cock to “OFF” and apply the
parking brake.

EBU00993
Parking on a slope
w
Avoid parking on hills or other inclines.
Parking 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.
1. Bring the machine to a stop by applying the
brakes in low gear.
2. Stop the engine and release the clutch
lever.
3. With the front and rear brakes applied, apply
the parking brake and slowly release the
brake pedal.

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