lowering the trem/getting the spring tension right/playing around with the trussrod...
If you know how to do it fine, if not either get a
guitar tech to do it for you (only needs to be done once unless you plan to change
string gauges). Or alternately get a good book on guitar setups and practice on a guitar that can get a bit hurt and when confident set up your 7dbk.
Have a look at some of the faq areas of jemsite, they should tell you a lot about what you need to know and how to do it.
