1. Use the Tailstock Quill Control Wheel
(84a) to position the Live Center. Turning
the Wheel counterclockwise slides
the Live Center away from the Chuck,
turning it clockwise slides it toward
the Chuck. It can be adjusted up to
approximately 2".
2. The Tailstock Quill (142) holds the
Live Center in place. To remove or
replace the Live Center, continue
turning the Tailstock Quill Control Wheel
counterclockwise until the Live Center
begins to slide out of the Quill. Insert
the Live Center or other tool (sold
separately) into the Quill and turn the
Tailstock Quill Control Wheel clockwise
to lock the tool in place.
3. You may need to slide the Tailstock
closer to, or further away from, the
Chuck before adjusting the Live Center.
To do so, loosen the Tailstock Nut (268),
adjust the Tailstock as needed, then re-
tighten the Nut. Use this method when
replacing the Tailstock as well.
