Depends on the exact switch.

Just experiment. There may be some interaction, but just pick one and turn it a turn one way or the other and see what happens. Pay attention to which way and how far you turn, until you have an idea of what they do.

Start with a half turn or so - the effect may not be huge, so pay close attention to what happens.

Note, too, that usually you won't get more than 30PSI or so of difference between cut-in and cut-out, no matter what you do.

Have fun.
