A chain saw cutting device and method for flush and square cutting walls and other flat concrete surfaces is disclosed. The chain saw cutting device is typically used in conjunction with a track-mounted circular saw cutting assembly, each being removably mounted either on a trolley which rides on, or directly to a track structure, which track structure is attached to the surface to be cut. The chain saw cutting device has an elongated bar and cutting chain which when mounted are positioned in the same cutting line made by the circular saw assembly. The carriage structure of the chain saw cutting device includes a reversible cutting drive and extends on only one side of a cutting plane containing the chain bar and cutting chain. Hence, the chain saw cutting device permits square cutting along the cutting line as well as flush cutting with respect to a perpendicular side wall, ceiling or floor. Removable chain guard extensions are attachable to protect the user during operation except in the flush and square cutting mode as necessary.
