ABSTRACT:
A hood for a power tool, such as a grinding wheel on a saw, in which the hood is rotatable relative to the frame of the tool. The tool has a system for repositionably fixing the hood at selected locations. The system includes a detent connected to the hood with a plurality of lock notches and a longitudinally movable lock pin connected to the frame. The lock pin can be positioned into one of the detent notches to prevent the hood from moving and, can be longitudinally moved to disconnect the lock pin from the detent thus allowing the hood to be repositioned. The system includes a knob to axially rotate the lock pin, a cam member to longitudinally move the lock pin upon axial rotation, and a leaf spring to bias the lock pin in an engaged lock position with the hood detent.
