ABSTRACT:
A power tool has a body with a motor disposed therein. The motor has a saw blade coupled therewith. A guard covers at least a portion of the saw blade. A window is pivotally mounted to the guard and movable between an open position and a closed position. The window has an abutment surface. A deformable elongated member has a first end fixed to the guard and a second end that is free to move with respect to the first end due to the deformable nature of the elongated member. The elongated member has a first position wherein the second end rests adjacent the abutment surface to prevent opening of the window. The deformable member is in a generally linear configuration when in its first position such that attempted opening forces are transferred along the axis of the elongated member. Said elongated member also has a second position wherein the member is deformed by an operator so that the first abutment surface and the second end are no longer adjacent one another, and wherein the window can be moved to an open position.
