ABSTRACT:
A chain saw guide bar has self-contained mechanism to force movement of the guide bar away from a drive sprocket to tension the saw chain. The mechanism includes a bearing surface that engages a mounting stud on the chain saw housing and a rotatable portion which upon rotation causes axial displacement of the bearing surface in contact with the stud.
