Every well pressure tank I've seen has the nearly-identical Square-D pressure 
switch on it.  Remove the cover (careful - there's live 240V) and there are two 
screws for high and low limit adjustment.  I don't know how high you can safely 
go...  mine was at 30/50psi, and I bumped it to 35/55.  Turning off the breaker 
to the pump can help, since you can let it run all the way down till the switch 
hits.  You need to adjust the air pressure to match, as well.  Kill the pump 
power, let it run all the way down, and the tank should be 2 or 3 psi below the 
low limit.
