The S-725 uses a gimbal mount at the front that pivots as the X or Z leadscrews are turned. These leadscrews put pressure against the leaf springs, noting the springs are not identical.

To disassemble for leadscrew cleaning, loosen the gimbal and gently pull out the arm assembly. You do not need to remove the leaf springs. I also disconnected the final head on the pivot head so that I could fully detach the arm, which was connected via a cable epoxied to the case.
