摘要： A power saw structure having a pivot provided on a forward lower portion of the housing of the drive for providing a fulcrum on a subjacent surface about which the saw structure may be pivoted so as to safely urge the forward distal end of the saw chain into the subjacent surface while maintaining the chain saw structure supported on the subjacent surface through the pivot. In the illustrated embodiment, the pivot structure is a separate structure secured to the housing of the drive. The pivot structure includes an upwardly extending forward portion for supporting the saw structure on the subjacent surface throughout the full range of swinging movement of the saw in cutting through the subjacent surface.
