ABSTRACT:
An apparatus for lubricating a chain saw mounted on the guide rail of a guide bar comprises a lubrication system for feeding a lubricant through a conduit in the guide bar to the saw chain while the guide bar is in the operating down position and the lubricant flow is interrupted when the guide bar is moved into the non-operating up position of the saw chain. The lubrication system provides a saving of lubricant by feeding it to the chain only during the working process and only to its essential working parts.
