A chain saw antipinch guard arm including an arm attached pivotally to a chain saw, the arm being movable in a plane substantially parallel to the plane of the blade. A handle extends upwardly from the arm and is pivotal therewith. The arm may be manipulated by the saw operator with a scissor-like action with respect to the blade and may be used for applying a force to the underside of a piece being sawn, thereby preventing pinching of the blade, while at the same time protecting the operator from injury.

In combination with a chain saw having an outwardly projecting blade mounting a saw chain having a working stretch, an antipinch guard attachment comprising: (a) a stiff arm of substantial strength; (b) pivotal mounting means mounting on one end of the arm on the saw adjacent to the base of the blade in a plane substantially parallel to the plane of the blade, the arm thereby being pivotal between an initial angular position wherein it extends divergently to the working stretch of the saw chain and a second angular position wherein it is adjacent and substantially aligned with the working stretch of the saw chain; and (c) elongated handle means attached to the arm for adjustment angularly relative thereto and for pivotal movement therewith.
