and fasteners before a ride. Take the machine
to a Yamaha dealer or refer to the Service

Starting a cold engine
w
Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or
do not work smoothly, you could be unable
to control the ATV, which could lead to an
accident or collision.
1. Set the parking brake.
2. Turn the fuel cock to “ON”.
3. Turn the main switch to “ON” and the
engine stop switch to “RUN”.
4. Shift the transmission into neutral.

Shifting
This model has a 3-speed forward transmission
with centrifugal automatic clutch. The transmis-
sion allows you to control the amount of power
you have available at a given speed or for start-
ing accelerating, climbing, etc. To shift into neu-
tral, return the throttle lever to its original posi-
tion and repeatedly depress the shift pedal until
it stops.
cC
Do not coast for long periods with the engine
off, and do not tow the machine a long dis-
tance. Even with gears in neutral, the trans-
mission is only properly lubricated when the
engine is running. Inadequate lubrication
may damage the transmission.

If your ATV has stalled or stopped and you
believe you can continue up the hill, restart care-
fully to make sure you do not lift the front wheels
which could cause you to lose control. If you are
unable to continue up the hill, dismount the ATV
on the uphill side. Physically turn the ATV
around and then descend the hill.
If you start to roll backwards, DO NOT use the
rear brake to stop or try to put the ATV in gear.
The ATV could easily tip over backwards.
Instead, dismount the ATV immediately on the
uphill side.

8If your ATV starts to slide sideways:
Steer in the direction of the slide if you have
the room.
Applying the brakes or accelerating is not rec-
ommended until you have corrected the slide.
(See pages 7-71 ~ 7-73.)
8If your ATV can’t make it up a hill you are try-
ing to climb:
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side
of the ATV and physically turn the ATV
around. If the ATV starts to slip backwards
DO NOT USE THE REAR BRAKE - the ATV
may tip over on top of you. Dismount the ATV
on the uphill side. (See pages 7-45 ~ 7-55.)

Idle speed adjustment
NOTE:
A diagnostic tachometer must be used for this
procedure.
1. Start the engine and warm it up for a few
minutes at approximately 1,000 to 2,000
r/min. Occasionally rev the engine to 4,000
to 5,000 r/min. The engine is warm when it
quickly responds to the throttle.
2. Connect the tachometer and set the idle to
the specified idling speed by adjusting the
throttle stop screw. Turn the screw in to
increase engine speed, and out to
decrease engine speed.q

6. Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.
7. Automotive type wax may be applied to all
painted and chrome plated surfaces. Avoid
combination cleaner-waxes. Many contain
abrasives which may mar the paint or pro-
tective finish.
When finished, start the engine and let it
idle for several minutes.
w
Wet brakes may have reduced stopping abili-
ty, increasing the chance of an accident.
Test the brakes after washing. Apply the
brakes several times at slow speeds to let
friction dry out the linings.
