Zusammenfassung:	A lubrication system for a hydraulically operated tool has a common lubricant supply manifold that receives a lubricant from one or more lubricant reservoirs. The common lubricant supply manifold includes an inlet port through which the lubricant is received and an exit port fluidly coupled with a lubricant supply line. The system also has a primer pump connected in fluid communication with the common lubricant supply manifold, a main lubricant supply pump, and a spring check valve downstream of the main lubricant supply pump. The lubricant supply line receives lubricant from the exit port and supplies the lubricant to the main lubricant supply pump. The main lubricant supply pump increases the pressure of the lubricant and pumps the lubricant through the spring check valve and into a fluid passageway leading to the hydraulically operated tool. A detune valve is in fluid communication with a hydraulic pump providing pressurized hydraulic fluid for the tool and the main lubricant supply pump, and the detune valve is actuated by pressure in the lubricant supply line.
