Automatic Power

Downfeed

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 the automatic downfeed. When the depth stop triggers the lower elevation limit switch, the handles spin rapidly as the spindle returns to its starting position. Failure to stay clear of the handles may result in injury.

To operate the automatic power downfeed:

1.DISCONNECT MACHINE FROM POWER!

2. Select the drilling option with the drilling/tap- ping switch.

3. set the spindle depth stop to the desired position (refer to Page 24).

4. Match the lines on the adjustment knob to select an automatic power downfeed option (see Figure 24).

—There are three options for the power downfeed mechanism that are located on the side of the adjustment knob:

0.2 is equal to 2mm of downfeed per spindle rotation.

0.1 is 1mm of downfeed per spindle rotation.

0.0 disengages the downfeed mecha- nism.
