Downfeed Controls
the quill downfeed movement is controlled by
three mechanisms: 1) the coarse downfeed
handle, 2) the fine downfeed handwheel, and 3)
the quill auto-downfeed system.
Coarse Downfeed Handle
1. turn the spindle motor OFF and wait for the
spindle to stop.
2. pull the quill auto-downfeed selector knob out
and rotate it clockwise to the disengage
(forward) position (see
figure 38).
NOTICE
to avoid damage to the quill auto-downfeed
gearing, always rotate the selector
CLOCKWISE.
3. align the pin in the handle hub with one of the
holes in the handle base, then firmly seat the
handle into the base (see
figure 39).
Note: If necessary, use the set screw on the
hub of the handle to adjust the detent ball
tension pressure so that the handle can be
installed and removed easily.
4. Make sure the quill lock is loose (see figure
39), then rotate the coarse downfeed handle
around its hub to control the depth of the
spindle.
