ABSTRACT:
The present disclosure concerns embodiments of an improved chainsaw guard. The saw guard includes a pivotable guard arm that may include downwardly extending saw chain guarding walls. In particular embodiments, the guard arm is pivotally connected to a mounting bracket, which is adapted to accommodate mounting the guard to the bar studs of various chainsaws having different bar stud spacing. The mounting bracket may be swept back to facilitate mounting to a wide variety of chainsaw models. The guard arm may include a handle adjacent the chainsaw housing to permit the guard arm to be lifted away from the guide bar so as to provide access to the upper run of the saw chain such as to perform maintenance or to permit positioning of the saw chain against a work piece in an undercutting operation.
