Abstract
A lubrication system for a hydraulic or pneumatic tool is described. The lubrication system includes a valve, a lubricant pumping mechanism and a lubricant storage chamber, the valve being adapted to move between a tool-deactivated position and a tool-activated position to cause the lubricant pumping mechanism to displace lubricant from the lubricant storage chamber. A method of distributing lubricant to a hydraulic or pneumatic tool is also described.
