A panel saw is adapted with an improved dust collection system including a protective blade cover having an oversized duct connected to a vacuum-type dust collection apparatus by a hose. The blade cover duct has an angled end configured to deflect and direct sawdust and wood chips downstream into the dust collection hose. A device that functions as both a guide and pulley is mounted to the top of the panel saw frame to allow the dust collection vacuum hose to travel over the frame in trailing relation with the carriage carrying the rotary power saw. The rotary power saw carriage is further adapted with a skirt attached in surrounding relation with the projecting saw blade and projecting therefrom in sweeping contact that defines a sawdust containment volume between the workpiece to be cut and the underside of the rotary saw power carriage. The panel saw frame is further adapted with a generally U-shaped sawdust channel connected thereto and disposed in vertical aligned relation with the saw blade so as to contain any sawdust projected behind the workpiece. A sawdust cup is connected to the bottom of the vertically disposed sawdust channel and functions as a catch basin for sawdust ejected into the channel. The sawdust cup includes a rearwardly projecting leg adapted for connection to a dust collection vacuum hose thereby providing the panel saw with a second dust collection connection.
