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 mill
OFF
and wait for the spindle to
stop.
2. pull the knob of the quill auto-downfeed
selector out and rotate it clockwise to the
forward disEngAgE (manual) position (see
Figure 35).
NOTICE
To avoid damage to the quill auto-downfeed
gearing, always rotate the selector clock-
wise.
3. Align the pin in the handle hub with one of the
holes in the handle base, then firmly seat the
handle onto the base (see
Figure 36).
4. Make sure the quill lock is loose (see Figure
36), then rotate the coarse downfeed handle
around its hub to control the depth of the
spindle.
