A saw guard system for enhancing the safety of use of powered hand saws by eliminating the need to hold the blade guard in a static position during the cutting operation. The saw guard system includes a circular saw with a housing, a motor positioned within the housing, a shaft extending from the motor through a wall of the housing, a blade operationally coupled to the shaft, and an upper blade guard for covering a perimeter edge of the blade above the shaft; a lower guard member pivotally coupled to the housing, a guard member motor coupled to the housing and the lower guard member for moving the lower guard member from the deployed position to the stored position; the guard member motor is operable separately from the motor of the circular saw; and a gear assembly operationally coupling the guard member motor to the lower guard member.
