those posts that go thru the bar(that the strigns go into) have lil holes at the top of the bar(that the strings go thru) you need to find a small allen/ or a presion screw driver, i can;t remember which and tighten them clockwise.
or you can do it by hand, since your trem is currectly off of the body.
also, i moved my spring on the farthest notch on the post.
creat a longer distance from the spring control point(bridge plate) and the post, that is conected to the bar that the strings go into.
plus you will need to set you intoneation, there are tons of great wbsites that will tell you how to do this properly.
i hope i explained it well enough for to understand.
