Moving the fulcrum point away from the primary
pump reduces the secondary stroke length, reducing
its fluid output. Moving the fulcrum point closer to the
primary pump increases the secondary stroke length,
increasing its fluid output.
1.
Use a wrench to rotate the ratio adjustment screw
(S). Rotate the screw clockwise to increase the
ratio. Rotate the screw counterclockwise to
decrease the ratio. The indicator pin (V) will move
along the ratio indicator scale (U) as the ratio
adjustment screw is rotated. See Fig 1, page 7.
2.
When the pin is above the desired ratio, remove
the wrench and perform a ratio test. See
