Abstract
A preferred embodiment of the present invention is directed to a modular saw guard system for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, wherein the system comprises a riving knife mechanism releasably mounted to the saw rearwardly of the blade, and being configured to be adjustable between retracted and extended positions relative to the blade, a blade guard mechanism that is releasably mounted to the riving knife mechanism and a kickback prevention mechanism that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the kickback prevention mechanism being configured to engage a work piece as it is being cut by the blade and apply resistance to prevent the work piece from being expelled in the reverse direction.
