ABSTRACT:
In a power saw, such as a power miter saw or chop saw, an approximately planar work surface is provided for supporting a workpiece, a frame is pivotally mounted adjacent to the work surface, and a blade is rotatably supported on the frame above the work surface. The frame and blade are pivotable between an upper, non-work position spaced away from the work surface, and a lower, work position located toward the work surface for engaging with the blade a workpiece supported on the work surface. A motor is mounted on the frame and is drivingly connected to the blade for rotatably driving the blade. An ergonomically-designed handle assembly is also mounted on the frame, and an arm of the assembly extends along a first plane oriented approximately parallel to the work surface when the frame and blade are located in the lowered, work position, and a handle projects downwardly from the arm and extends along a second plane oriented at an angle of at least approximately 50.degree. relative to the first plane. A trigger switch is positioned on the underside of the handle for engagement by at least the index and middle fingers of the hand to thereby depress the trigger and actuate the motor and blade. A safety switch is coupled to the trigger for selectively releasing the trigger, and is positioned opposite the trigger at the junction of the handle and arm for facilitating its engagement by the thumb of the same hand engaging the trigger to release and in turn depress the trigger for actuating the motor and blade.
