On the 511A I use a new chain (or one with equal length cutters), to center the chain. Set the vise at 30* right; adjust the 'dog' so that the grinding wheel just touches the front edge of the tooth. Rotate the vise to 30* left; see where the grinding wheel touches the front edge. Adjust the screw and lock nut until they are equal.
Note that this setting might need to be readjusted as the diameter of the grinding wheel changes with wear.
The 511AX is supposed to be self-adjusting.
