ABSTRACT:
An attachment for a chain saw (100) includes two elongated members (4D) mountable on the opposite faces of the chain guide (102). Each member (4D) has an elongated center portion (6D) configured to be secured to the chain guide (102) in a position closely adjacent to the corresponding face thereof. An angled portion (30) extends laterally outwardly from the outer edge of the center portion (6D). A plurality of spaced apart teeth (12D) project from the angled portion (30) substantially parallel to the chain guide (102) over and beyond the chain (104). Each tooth (12D) has, on an upstream edge thereof, a surface (18D) angled laterally outwardly in an upstream direction to help retain the chain on a path around the periphery of the chain guide (102). The angled surface (18D) is preferably formed by bending the edge of a substantially flat tooth. The surface (18D) preferably extends along the tooth (12D) from its pointed tip portion (36) to and along a radiused junction (34) with the angled portion (30) of the elongated member (4D).
