Abstract
The specification discloses a chain saw having a saw bar which is fastened to the frame of the chain saw so that most of the saw bar is outward of the chain saw frame (referred to as the forward portion), which portion is exposed for effective cutting, but with a lever portion rearward of the frame and the drive sprocket of the chain saw for improved mounting and adjustment. The saw bar forms a part of a cassette which also includes a drive sprocket trapped in the saw bar and a saw chain extending around the sprocket and the forward portion of the saw bar. A cover has clamping bosses clamping the saw bar to the frame, and an adjustment screw engaging the rearward end of the saw bar is mounted on the frame at the rear thereof so that it is readily accessible.
