Claim:
A power circular saw comprising: a motor housing; a motor having an output shaft located in the motor housing, a circular saw blade operatively driven by said output shaft, said blade being positioned to cut a work piece as said saw is moved in a forward direction, a foot structure connected to said motor housing and having a bottom surface for contacting a work piece; a protective blade housing surrounding approximately the portion of the saw blade that is located above said foot structure bottom surface; a fan blade operatively driven by said output shaft and positioned in said motor housing to draw air past said motor for cooling the same; said motor housing having at least one motor exit opening defining an air flow exit through which air generated by the fan passes, said motor exit opening being on the front of said motor housing so that air is expelled forwardly for the purpose of removing debris from the line of cut during operation of said circular saw; a bevel adjustment mechanism including a bevel quadrant connected to said foot structure, said bevel quadrant being located near the front of said foot structure and including a bevel pivot connection that permits said motor housing, blade and blade housing to be pivoted along a lengthwise axis substantially parallel to the plane of said saw blade; wherein said bevel quadrant has a generally triangular configuration with an arcuate slot in which a locking mechanism is located, said locking mechanism sliding along said slot when said bevel adjustment mechanism is adjusted to vary the angle of said bottom surface of said foot structure relative to the plane of said saw blade, said quadrant having at least three openings through which air can pass toward the work piece.
