Using the controls on the lathe, follow along with
the example below to better understand how to
set the lathe for the desired power feed rate.
C. Feed Selection Lever:
Engages cross slide or
carriage for power feed operations.
Note:
When using this lever, you may need
to slightly rotate the handwheel of the
component you are trying to engage, so
apron gears can mesh.
To position the lever (see Figure 58) for
either cross slide or carriage feed, begin at
the middle position, pull the lever straight
out, and rotate it to the desired setting.

When the left/right arrows on the lever are
visible, the lever can be shifted up to select
the carriage (see Figure 59).
Conversely, when the lever is rotated 180˚,
and the up/down arrows are visible, the lever
can be shifted down to select the cross slide.
