Abstract
A viewing window for covering an aperture in a hand-held circular saw includes an optically transmissive member adapted to be coupled with the guard. The member is movable between a closed position, wherein the member substantially covers the aperture, and the open position, wherein the member at least partially uncovers the aperture, to allow the cleaning of the member. A structure is provided for biasing the member to the closed position.
