There are two adjustments, a Coarse adjustment and a Fine Adjustment. The Coarse adjustment is the nut at the bottom of the machine. There are two nuts, the bottom nut (closes to the end) is a lock nut, and the other is the adjustment nut. The fine adjustment is the one inside the base clamp, that you access with a 3mm allen wrench.

Many of the newer clamps have the Fine adjustment screw on the outside, like the Gamma Switch Action Clamps.

Ok,thanks a bunch!
