APRON CONTROLS (LEVER TYPE)

In addition to handwheel traverse, the carriage can
be power-operated through controls on the front
of the apron, see Figure 16 knob (A). Automatic
feed lever (A) if moved upwards, the carriage will
do longitudinal-feed operation. If the lever (A) is
placed in middle position, it will perform manual
operation. If the lever (A) is moved downward, it
will perform the cross-feed operation.
Lever (B) is pressed downward to engage the
leadscrew nut for threading. To avoid undue wear,
