Important:
Do not force any selection lever on the machine. If the lever will not engage, rotate the chuck by hand while keeping light pressure on the selector. As the chuck rotates, it aligns the gears and the selector will engage.
To change the position of the feed selector, pull the knurled handle. This disengages a pin which is inserted into a selection hole. Position the lever in the down position and slide to the right or left until it is positioned below the desired selection hole. Raise the lever with one hand while pulling the handle with the other. The pin at the end of the lever should align with the selection hole. If it does not, rotate the feed rod or chuck by hand while maintaining gentle pressure on the lever.
Feed Rate Chart
To perform a longitudinal cut in inches, use the bottom portion of the chart. If the desired feed rate is 0.0062"/revolution, look at the longitudinal ranges. According to the chart we would put the
Please note that when either of the two selector levers are left in the down position, the drive train after this point is in neutral.

Moving this lever upward activates the automatic longitudinal feed. Moving the lever down activates the cross slide. See Figure 13.
