Note: Before using power feed, you may have to
re-configure the end gears, depending on how
they are set up. Refer to End Gears on Page 56
for detailed instructions.

Feed Control Lever: Directs the power feed
to either the cross slide or the carriage (see
Figure 80).
When the lever is down and the indent pin
is pointing up, the cross slide is selected.
Conversely, when the lever is up and the pin is
pointing down, the carriage is selected.
In the middle position, the apron gears are
disengaged from the feed rod and neither
component will move.
Note: When using this lever, you may need to
slightly rotate the handwheel of the component
you are trying to engage, so that the apron gears
can mesh.
