 Avoid short clamping contact (A, Figure 10-3) or
clamping on a minor part diameter (B, Figure
10-3). Face-locate the workpiece for added
support.

10.1 Feed and Thread Selection
To obtain various feed settings and thread pitches,
the knob and two levers (J, Figure 10-4) are used
conjunctively. Position the levers according to the
Feed and Thread Chart on front of end cover. An
identical chart is shown in sect. 13.0.
TIP: When selecting feed/speed correlations,
remember the general principal that high speeds
complement fine feeding, and low speeds are better
for coarse feeding.

10.2 Thread cutting
Threading is performed in multiple passes, with
increasing depths in succeeding cuts. It is
recommended that test cuts be made on scrap
material and the results checked before proceeding
with regular material.
1. Move feed direction lever (H, Figure 10-4) for
right-hand or left-hand threads.
2. Set spindle to low speed range (G/E, Figure 10-
4). Use lowest speed possible when threading.
3. Turn knob (J

, Figure 10-4) clockwise to
disengage feed rod.
