Power Feed Controls
Use Figures 72–73 and the following descriptions
to become familiar with the locations and func-
tions of the controls that you will use to set up the
correct power feed for your operation.
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 55
for detailed instructions.
A. Feed Range Lever: Selects the low or high
feed rate range by re-aligning the headstock
transfer gear. In the middle position, disables
power feed.
B. Feed Direction Lever: When the lathe is
stopped, selects the direction for power
feed.
Note: When the lathe is running, use the
quick-change feed direction knob on the
apron.
C. Feed Rate Chart: Displays the settings for
the headstock and quick-change gearbox
controls for the selected feed rate. Refer to
Setting Power Feed Rate subsection on the
next page for detailed instructions.
D. Quick-change Gearbox Feed Levers:
Configure the quick-change gearbox gears
for the feed rate selected.
— Left Lever Positions: A–C
— Middle Lever Positions: R–T
— Right Lever Positions: V–Z
— Bottom Lever Positions: 1–8
If the spindle is rotating when attempting to
change the configuration of the headstock
feed controls, the gears in the headstock
and quick-change gearbox will become
damaged! ALWAYS make sure the spindle
is completely stopped BEFORE using the
headstock control levers to make changes.
Even though there is a lock-out device in
the apron to prevent the feed selection lever
and the half nut lever from being engaged
at the same time, this lock-out device could
break if forced. Attempting to engage these
levers at the same time could cause severe
lathe damage and will void the warranty.
