Turn off the electricity to the pump.
Take the plastic cover off the square d and you'll see the adjustment nut with a spring under it on the long threaded stem sticking up between the contact points.
Tighten the nut down several turns, turn the pump back on and check the pressure cut off again.
Keep that up til you get it where you want it.
I run my A.O. Smith 3/4 and 1 hp deep well pumps at 40/60 settings.
I think you would be happier with yours to set it for at least 25-30 lbs cut in.
