The ST-10 tailstock is manually positioned, then the quill is hydraulically applied to the workpiece. Command hydraulic quill motion using the following M-codes:

M21: Tailstock Forward

M22: Tailstock Reverse

When an M21 is commanded, the tailstock quill moves forward and maintains continuous pressure. The tailstock body should be locked in place before commanding an M21.

When an M22 is commanded, the tailstock quill moves away from the workpiece. Continuous hydraulic pressure is applied to prevent the quill drifting forward.
