Setting Feedrate

1. Turn the spindle OFF and wait until it comes

to a complete stop before making any gear
changes.

2. Move the feed rod lock knob to the open

position (see

Figure 53). This will disengage

the feed rod so gears can be changed.

C/D/E/F Feed/Lead Selector

1-8 Feed Rod Selector

For example: To set the lathe to the slowest
feed rate of 0.0011" per inch, locate 0.0011
on the chart. The lever combination on the
chart is B, F and 8. Set the appropriate levers
to these positions.

Note: You may need to rotate the chuck by
hand or move the longitudinal handwheel to
get selectors and gears to engage.

5. Return the feed rod lock knob to the locked

position to engage the feed rod.

3. Examine the feed/thread chart (Figure 55) to

determine the correct lever combination for
the desired feedrate.

4. Feeds rates are controlled by the combina-

tion of three different switches. The A/B feed/
lead selector in

Figure 54, the 1-8 feed rod

selector, and the C/D/E/F feed/lead selector
combinations in

Figure 54.
