Power Feed Controls

Use Figures 67–71 and the following

descriptions to become familiar with the locations

and functions of the controls that you will use to

set up the correct power feed for your operation.

Note: Before using power feed, you may have to

re-configure the end gears, depending on how

they are set up. Refer to End Gears on Page 58

for detailed instructions.

Gearbox Range Lever: Selects the low or high

feed rate range by re-aligning the headstock

transfer gear. In the middle position, disables

power feed (see Figure 67).

Headstock Feed Direction Lever: Selects the

direction of power feed (see Figure 68).

Note: The spindle must be stopped to use this

lever. When the lathe is running, use the apron

feed direction knob.

Quick-Change Gearbox Feed Levers: Configure

the quick-change gearbox gears for the feed rate

selected per the feed chart (see Figure 69).

Operating the lathe at spindle speeds higher

than 350 RPM could result in gearbox damage

when the high (H) gearbox range is selected.

Always use spindle speeds of 350 RPM or

lower when using a high gearbox range.
