How do you adjust the points on a well pump?

If you mean cutin/cutoff points, then go here for a good description:

How to adjust water pump pressure, pump cut-on pressure and pump cut-off pressure - private pump and well system do-it-yourself repairs (http://www.inspect-ny.com/water/WaterPumpAdjust.htm)

If you mean the contact points themselves, then the answer is... you don't. They can be cleaned but not adjusted.
