You just need to take the cover off the back of the guitar and adjust the springs....You'll need to tighten the screws to make the springs have more tension to pull the trem unit back down....It'll take some time, so don't get frusterated...Floating trem's can be a pain in the ass to get set up right. First adjust the springs to where the action is where you want it, then tune the strings, then adjust the springs, tune the strings.....keep going back and forth between the strings and springs and it'll eventually work itself out.
