Quick-Change Gearbox Feed Levers: Configure
the quick-change gearbox gears for the feed rate
selected per the feed chart (see Figure 70).
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.
