ABSTRACT:
A motorized saw comprising a base having a work piece support, and a cutting station at which a work piece is cut; a cutting unit including a motor, an arbor on which a saw blade can be removably mounted for rotation about an arbor axis driven by the motor, and a movable guard, movable between surround and non-surround positions relative to a lower portion of the saw blade; mounting apparatus securing the cutting unit on the base for movement between a non-cutting position remote from the cutting station and a cutting position which places the saw blade at the cutting station; a movable guard actuating apparatus connected between the base and the movable guard to progressively move the movable guard toward the non-surrounding position as the saw blade cuts through the work piece at the cutting station, the actuating apparatus includes a lost motion member permitting the movable guard to be freely moved by manual actuation thereof to the non-surrounding position only when the cutting unit is in the non-cutting position to expose the saw blade for removal; a lockout apparatus automatically contactable by the movable guard actuating apparatus when the movable guard is in the non-surrounding position for preventing movement of the cutting unit from the non-cutting position until the movable guard is returned to the saw blade surrounding position.
