MECHANICAL ADVANTAGE FOR MANUAL PUMP LEVER
7J - The lever fulcrum may be mounted in either of two positions. One delivers higher pressure per 100 pounds lever load (max. leverage). The other delivers greater displacement (output) per lever stroke (std. leverage). (See tables for data.) In addition, a handle extension is provided to increase the advantage for higher pump pressures.
