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:

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.
