-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.
