Should the ATV be separated from the parent by
a distance longer than the lanyard length, the
lanyard will pull out the clip and stop the engine.
For further explanation of this switch and the
lanyard, see “TEACHING YOUR CHILD TO
OPERATE THE ATV” in the “SAFETY INFOR-
MATION” section.
NOTE:
8The engine cannot be started with the clip
removed.
8When your child has developed sufficient skill
to no longer need you to follow with the lan-
yard, the lanyard can be stowed under the
seat of the ATV. However, you must still
closely supervise your child at all times during
ATV operation.

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 froze or do
not work smoothly, you could be unable to
control the ATV, which could lead to an acci-
dent 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.

To start out and accelerate:
1. Release the throttle lever.
cC
Always close the throttle before shifting the
transmission into the drive position.
Otherwise, damage to the engine and drive
train may result.
2. Apply the parking brake. (See page 6-23.)
3. Shift the transmission into the drive posi-
tion.
NOTE:
Before shifting the transmission into the drive
position, be sure to apply the parking brake. The
engine will stop if you attempt to shift into drive
without applying the parking brake first.

With the engine idling, shift the transmission into
the drive position and then release the parking
brake. Apply the throttle slowly and smoothly.
The centrifugal clutch will engage and you will
start to accelerate. If the throttle is applied too
abruptly, the front wheels may lift off the ground
resulting in a loss of directional control. Avoid
higher speeds until you are thoroughly familiar
with the operation of your ATV.
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. Improper use of the brakes can cause
the tires to lose traction, reducing control and
increasing the possibility of an accident.

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, apply the front brake gradually, or dis-
mount 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 7-69–7-71.)
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. Instead, apply the
front brake or dismount the ATV on the uphill
side. (See pages 7-43–7-53.)

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 to the spark plug
lead, and then set the idle to the specified
idling speed by adjusting the throttle stop
screw. Turn the screw in direction ato
increase the engine speed, and in direction
bto decrease the 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.
