Auto-Feed
To operate automatic powered downfeed:
1. DISCONNECT MACHINE FROM POWER!
2. Turn drilling/tapping switch left to select "drill-
ing" mode.
3. Set spindle depth stop (refer to Page 23 if
necessary).
4. Match lines on adjustment knob (see Figure
26) to select automatic powered downfeed
option as follows:
• 0.2 = 0.20mm of downfeed/rotation.
• 0.1 = 0.10mm of downfeed/rotation.
• 0.0 disengages downfeed mechanism.
This drill press comes with automatic downfeed
control for repeated drilling operations at the
same depth. The automatic downfeed only works
in the drilling mode.
Stay clear of coarse downfeed handles while
using automatic downfeed. When depth
stop triggers lower elevation limit switch,
handles spin rapidly as spindle returns to
its starting position. Failure to stay clear of
handles may result in injury.
5. Reconnect machine to power.
6. Turn master power switch to ON position,
ensure EMERGENCY STOP button is not
pressed in, and press Spindle Start button.
7. Push downfeed engagement lever (see
Figure 27) up to activate automatic downfeed.
Note: If set correctly, depth stop will push
downfeed engagement lever down and auto-
matically disengage powered downfeed.
