9. Slowly increase each UP/DN air regulator setting by
alternating pattern 5-10 psi (0.035-0.07 MPa,
0.35-0.7 bar) at a time until the approximate stall
(static) pressure is achieved on fluid gauges (GA)
and (GB). Leave UP stroke regulator setting at
approximately 10 psi (0.07MPa, 0.7 bar) lower than
DN stroke.
