NOTICE
ALWAYS make sure the spindle is turned OFF and is at a complete stop before changing any gear configuration to prevent damage to the lathe gearing and voiding the warranty.
Setting Feed Rate Controls
The feed rate lever and knobs are used with the quick change gears to set the required feed rate.
To set the feed controls:
1.Turn the spindle OFF and wait for it to come to a complete stop before making any gear changes.
2.Rotate the feed lock knob on the gearbox counterclockwise to the open position, as shown in Figure 57. This will disengage the feed rod and longitudinal leadscrew so the gears can be changed.

3.Examine the feed rate and threading charts illustrated in Figure 55 on Page 41 or on the front of the headstock to determine the con- figuration for the feed rate lever and knobs.
4.Set the feed rate lever and knobs as directed in the charts.
The example illustrated in Figures 58–59 shows the setting for cutting 11 TPI threads— A, 4, and C.
Note: You may need to rock the spindle, leadscrew, or feed rod
