ABSTRACT:
A guide shoe of a power chain saw unit is movable along a series of side-by-side roof rafters. A power chain saw of the power chain saw unit is connected to the guide shoe by rigid rods. When operated, the power chain saw cuts notches in the roof rafters in the direction of travel of the guide shoe. Fixed to the guide shoe are upstanding plates formed with arcuate slots. The ends of the rigid rods adjacent the upstanding plates are releasably secured along the arcuate slots of the upstanding plates for locking the power chain saw in various selected angular positions relative to the guide shoe for controlling the depth of the notches and the cutting angle of the chain saw blade of the power chain saw.
