8In 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.
8Make sure that no foreign material enters
the crankcase.
Recommended engine oil type and quantity:

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.

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 centrifugal clutch will engage and you will
start to accelerate. 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 procedure as you move into the high-
er 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 resulting in a
loss of directional control. Avoid higher speeds
until you are thoroughly familiar with the opera-
tion of your ATV.
