ABSTRACT:
An improved guide bar for a chain saw having two sawdust kick-out holes in the rear of the guide bar. Each kick-out hole passes completely through the guide bar and through a guide groove in the bar. Also provided are at least two lubricating holes in the guide bar which extend through the bar and guide groove. The lubricating holes are straight holes transverse to the guide groove with a countersunk portion at the outer edge thereof, and the lubricating holes are designed to communicate with a lubricating means in the chassis of the saw, so that lubricating oil can be supplied into the guide groove. Also provided is a special sawdust plate designed to fit between the bar and the chassis of the saw.
