The PTO shaft should maintain a minimum engagement of
1/3 of the total compressed shaft length.
If the PTO shaft maintains at least 1/3 shaft engagement,
you will be operating within the proper range of the shaft.

If the PTO shaft does not maintain at least 1/3 shaft
engagement, you will not be operating within the
proper range of the PTO. You will need to either install
a longer PTO shaft, or avoid this area when cutting.

Gearbox
Check the oil level and condition in the gearbox. The oil
level should be 1/4” to 3/8” below the bottom edge of the
side plug. The gearbox should be approximately half full
(28 ounces). Add oil if low. If the oil appears excessively
contaminated, change the oil. Use SAE 80W-90 grade gear
oil.
Inspect the entire area around and under the gearbox for
any oil leakage. If a leak is discovered, repair it and refill the
gearbox before operating the Articulator.
