Coarse Downfeed
Use the coarse downfeed lever to quickly move
the spindle manually.
To use the coarse downfeed:
1. Make sure the spindle is completely stopped.
2. Pull the downfeed selector knob out, then
rotate it clockwise until the knob pin seats in
the forward manual (disengaged) detent (see
Figure 35).
Note: It may be necessary to turn the spindle
by hand as you move the selector to enable
the gears to mesh.

4. Make sure the quill lock lever is loose so that
the quill can easily move.

hub to control the depth of the spindle.
Fine Downfeed
1. Make sure the spindle is completely stopped.
2. Pull the downfeed selector knob out, then
rotate it clockwise until the knob pin seats in
the forward manual (disengaged) detent (see
Figure 35).
Note: It may be necessary to turn the spindle
by hand as you move the selector to enable
the gears to mesh.
3. Set the auto-downfeed direction pin in the
neutral (middle) position to disengage the
fine downfeed handwheel from the auto-
downfeed gears.
4. Position the downfeed stop for the spindle
depth that is correct for your operation, then
secure it in place with the locking wheel.
5. Use the coarse downfeed lever to lower
the spindle slightly until you can pull the
fine downfeed clutch lever out to the left
and it locks in place. This will engage the
fine downfeed handwheel with the quill and
spindle.
6. To lower the spindle, rotate the fine downfeed
handwheel. When the quill dog meets the
downfeed stop, the clutch lever will disen-
gage and the spindle will return to the top.
