it clockwise until knob pin seats in the forward
manual (disengaged) detent (see

Note: It may be necessary to turn the spindle
by hand as you move the selector to enable
the gears to mesh.
3. Set auto-downfeed direction pin in the neutral
(middle) position to disengage fine downfeed
handwheel from auto-downfeed gears.
4. Position downfeed stop for desired spindle
depth, then secure it in place with locking
wheel.
5. Use coarse downfeed lever to lower spindle
slightly until you can pull fine downfeed clutch
lever out to the left and it locks in place. This
will engage fine downfeed handwheel with
quill and spindle.

handwheel. When quill dog meets downfeed
