Abstract
A miter saw has a base on which a workpiece is placed, a miter saw unit substantially vertically pivotally mounted on the base, a drive supported by the miter saw unit for driving a rotary tool, a blade case mounted on the miter saw unit and partly covering the rotary tool so as to provide an exposed operational portion of the rotary tool, a safety cover pivotally mounted on the blade case for covering the exposed operational portion of the rotary tool, and an actuating link having a slot formed substantially the central portion thereof. One end of the actuating link is pivotally connected with the base, while the other end of the actuating link is engaged with the safety cover. A guide member is mounted on the blade case and is engaged with the slot of the actuating link. The safety cover is pivoted to uncover the exposed operational portion of the rotary tool in association with the movement of the engaging portion of the slot with the guide member as the miter saw unit is pivoted downwardly toward the base.
