ABSTRACT:
Improved apparatus for supplying lubricating oil to the chain of a chain saw powered by an internal combustion engine. A lubricating oil tank is pressurized by communication with the crankcase of the engine, and the pressure forces oil from the oil tank to lubricate the saw chain. An air control valve is disposed in the air passage between the crankcase and the lubricating oil tank, and this valve is selectively operable to adjust the pressurization of the oil tank. The control valve is manually adjustable to adjust the pressurization of the lubricating oil tank, so as to accommodate changes in lubrication caused by factors such as changes in temperature, lubricating oil viscocity, or the like.
