Parts #29 are the adjusting screws. The left one is the high pressure = relief valve (small ball, approx. 600 psi/turn). The right one is the low = pressure relief valve (large ball, approx. 350 psi/turn). To adjust, loosen jam nut, turn adjusting screw cw to raise pressure ccw = to lower pressure. =20 To check the relief valve setting force the pump to stay on (jumper across = the pressure switch) and measure the pressure in the system. Err on the = low side when making changes as the pump can put out 3000 psi. Chris Zavatson N91CZ 360 std
