Abstract
Embodiments include a bar for a chain saw that is equipped with one or more oil channels that run along the length of the bar. Each oil channel receives oil at a first end, which exits the oil channel at an oil exit aperture at a second end of the channel. The oil exit aperture of one of the channels is positioned along the side of a bar groove, through which runs the saw chain, proximate to the cutting area of the bar to lubricate the saw chain just prior to the cutting area. A second channel may have an oil exit aperture proximate to the nose of the bar, to lubricate a sprocket wheel in the nose of the bar.
