A power miter saw includes a support base and a mounting arm connected to the support base for swinging movement around a vertical axis. A miter saw unit is pivotally connected to the mounting arm. The miter saw unit includes a circular saw blade and a drive motor for driving the saw blade. A blade case is attached to the miter saw unit and is adapted to partially encase the saw blade so as to provide an exposed operational portion of the saw blade. A movable safety cover is mounted on the blade case so as to cover the exposed operational portion of the saw blade. Actuating means is disposed between the mounting arm and the safety cover for directly associating the safety cover with the pivotal movement of the miter saw unit.
