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.

[ What is claimed is:] [1.] A sliding saw for performing cutting operations on a workpiece, said saw comprising:a base assembly for receiving the workpiece;a support assembly interconnected with said base assembly;a drive assembly comprising a motor, an arbor shaft rotatable about an arbor axis, and a cutting tool driven by said motor about said arbor shaft, said drive assembly being pivotally interconnected with said support assembly for selective pivotal movement of said motor and said cutting tool relative to said support assembly between an at-rest position wherein said cutting tool is out of engagement with the workpiece and an operational position wherein said cutting tool is in a cutting engagement with the workpiece, said drive assembly being slidably movable relative to said support assembly;a guard assembly including a fixed guard partially surrounding a cutting periphery of said cutting tool and a movable guard, said fixed guard being fixedly interconnected with said drive assembly, and said movable guard being pivotally interconnected with said drive assembly for pivotal movement between a closed position surrounding a predetermined portion of the cutting periphery of said cutting tool and an open position covering a lesser portion of the cutting periphery of said cutting tool than when in said closed position;an engaging portion movable between a first position engaging the movable guard and a second position not engaging the movable guard, so that the drive assembly cannot be pivoted downwardly when the engaging portion is in the first position; anda hook portion disposed on one of the drive assembly and the support assembly for engaging a protrusion on the other one of the drive assembly and the support assembly, the hook portion preventing slidable movement of the drive assembly relative to the support assembly until the drive assembly is pivoted downwardly.
