How To Adjust The Pressure Switch Of Piston C ompressor 1.  Turn   off   the   compressor   and   remove   the   cover   from   the   switch exposing   the   adjustment   nuts.   Be   sure   not   to   touch   the   electrical terminals turning the circuit breaker off is recommended. 2. You will see two nuts with springs under them. The larger one is to increase the pressure the smaller one is to decrease the pressure. We factory set these at 145PSI.  3.  To adjust the pressure ranges turnthe nut on the large central post clockwise to increase the pressure range. Turn the nut through 3 1/2 rotations to increase the range by 10 psi. For example if the current range is 20/40 psi which means the pump cuts in at 20 psi and cuts out at 40 psi turning the nut through 3 1/2 rotations increases the range to 30/50   psi.   Turn   the   nut   counterclockwise   by   the   same   amount   to decrease the range. 4. To adjust the differential Turn the nut on the smaller of the two posts clockwise to increase the range between the cut­in and cut­out pressures.
