Abstract

In one embodiment, the anti-pinch device includes a vertical support mounted normal to the saw blade of the chain saw. A pinch arm extends longitudinally above the saw blade and is mounted for translational movement along the length of the vertical support. The pinch arm is attached to a transversely movable mount by a pivot such that the pinch arm can pivotally move with respect to the vertical support and the mount and pinch arm can transversely move up and down the vertical support in a substantially free manner.
