ABSTRACT:
A guard assembly for a saw or other cutting device includes fixed and movable guards relatively pivotal by way of a linkage assembly having two links pivotally interconnected coaxially with a cam roller engageable with a cam surface for controlling relative guard movement. Other preferred features include a torsional coil guard return spring and spring enclosure that minimizes interference with workpiece cutting depth, an arbor shaft cover retention fastener that doubles, along with another caliper member, as a blade caliper set that prevents guard damage in the event of a bent or deflected blade or cutter, a drive assembly hold-down assembly for storage, and a horizontally-extending handle centered horizontally relative to the blade or cutter.
