ABSTRACT:
A chop saw arrangement having an improved lower blade guard pivoting mechanism. An upper safety guard is pivotally supported to a hinging member, and a circular saw blade is rotatably supported to the upper safety guard. A collar is attached to the upper safety guard, and a swingable arm pivotally connected to a supporting arm has a cam portion engageable with the collar. Angular position of the swingable arm is defined by the abutment between the cam and the collar. The swingable arm has an end portion pivotally connected to one end of a link member whose other end is pivotally connected to a lower blade guard. The lower blade guard is pivotally supported to the upper safety guard coaxially with the circular saw blade. Angular position of the lower blade guard is defined by the pivotal movement of the swingable arm through the link member.
