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.
La présente invention vise un regard à glace destiné à recouvrir une ouverture pratiquée dans le protège-lame d'une scie circulaire, constitué d'un élément transparent permettant de voir la lame. L'élément en question est mobile et peut se déplacer entre une position fermée, où il recouvre toute l'ouverture, et une position ouverte, où il recouvre au moins partiellement l'ouverture, et où il peut être nettoyé. Un dispositif est prévu pour ramener l'élément en position fermée.
