Using Coarse Downfeed
Coarse downfeed is typically used for drilling,
because it allows you to quickly lower the spindle
with varying speed/pressure, and it automati-
cally retracts the spindle to the top position when
released.
Note: To maintain control of the upward spindle
travel and the rotating bit in your workpiece,
always continue holding the lever until the spindle
returns to the top position. Letting go of the lever
too soon will cause the spindle to retract too
quickly and slam up into the headstock.
To use coarse downfeed:
1. DISCONNECT MACHINE FROM POWER!
2. Make sure spindle is completely stopped,
then pull downfeed selector out and rotate it
until it seats in manual (disengaged) position
(see Figure 40).
Note: It may be necessary to turn the spindle
by hand as you move the selector to enable
the gears to mesh.
