6.Replace the two belt housing side covers before re-connecting the mill to power.

To avoid entanglement hazards, always make sure that the two belt housing safety covers are firmly in place before connecting the mill to power.

Downfeed Controls

Spindle downfeed movement on the mill is controlled by three mechanisms: 1) The coarse downfeed handle, 2) the fine downfeed handwheel, and 3) the auto-downfeed system.

Using the Coarse Downfeed Handle

1.Make sure that the spindle rotation is turned OFF and the spindle is at a complete stop.

2.To set the downfeed for manual control, pull the downfeed selector knob out, then rotate it clockwise until the selector pin under the knob seats in the forward manual (disengaged) position, as shown in Figure 38 and illustrated in Figure 39 on the next page.

Note: It may be necessary to turn the spindle by hand as you move the selector to enable the gears to mesh.
