CAUTION:_
In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD”
or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING II” or higher.
Make sure that no foreign material enters
the crankcase.

Shifting
This model is equipped with a dual, 5-speed for-
ward and 1-speed reverse transmission with a
centrifugal clutch. The transmission allows you to
control the amount of power you have available at
a given speed or for starting, accelerating, climb-
ing hills, reverse, etc. To shift into neutral, return
the throttle lever to its original position and repeat-
edly depress the shift pedal until it stops.CAUTION:
Do not coast for long periods with the engine
off, and do not tow the machine a long dis-
tance. Even in neutral position, the transmis-
sion is only properly lubricated when the
engine is running. Inadequate lubrication may
cause damage.

With the engine idling, lift the shift pedal to the 1st
gear position and then release the parking brake.
Apply the throttle slowly and smoothly. The centrif-
ugal clutch will engage and you will start to accel-
erate. Once the ATV has attained adequate
speed, release the throttle and lift the shift pedal to
the 2nd gear position. Release the shift pedal and
apply the throttle smoothly. Use this same proce-
dure as you move into the higher gears. Be sure to
coordinate the use of the throttle and shift pedal
properly. If the throttle is applied too abruptly or if
the throttle is not released during shifting, or if the
shift pedal is not released before applying the
throttle, the front wheels may lift off the ground re-
sulting in a loss of directional control. Avoid higher
speeds until you are thoroughly familiar with the
operation of your ATV.CAUTION:_ Do not shift gears without releasing the throt-
tle. Damage to the engine or drive train may oc-
cur. _
