Power Feed
The carriage has power feed (or automatic feed)
options for threading or non-threading operations.
This section describes how to use the power feed
option for non-threading operations. To learn how
to power the carriage for threading operations,
refer to
Threading on Page 58.
Power Feed Controls
Use the following descriptions and figures to
understand the power feed controls.
Before using power feed, you may have to recon-
figure the end gears, depending on how they are
set up (refer to
Power Feed Configuration on
Page 52). The lathe comes from the factory with
the end gears set up in the power feed configura-
tion.

or reverse carriage travel when feed direction
dial and half nut lever are engaged. The car-
riage will not move when the switch is in the
"0" position.
