You'll likely find 2 adjustments, each associated with a compression spring 
(probably a screw through the center of the spring).  One adjusts the 
cut-out pressure (the thicker/stronger spring) while the other adjusts the 
differential between cut-in and cut-out pressures (ie the number of PSI drop 
from the cut-out pressure before the unit turns on again).

Tightening the cut-out spring raises the cut-out pressure, and tightening 
the differential spring increases the differential between cut-out and 
cut-in pressure.
