Abstract

A power saw includes a base portion, a support assembly, a cutting arm, a blade guard, a linkage arm, and a biasing member. The support assembly is supported by the base portion. The cutting arm is supported by the support assembly and is configured to rotatably support a saw blade. The cutting arm is movable between a lower position adjacent to the base portion and an upper position spaced apart from the base portion. The blade guard is rotatably supported by the cutting arm and is configured to receive a portion of the saw blade therein. The linkage arm includes a first end portion pivotally connected to the blade guard, and a second end portion movably supported by the support assembly. The biasing member is operably connected to the second end portion and is configured to bias the linkage arm.
