Power Feed Controls
Use Figures 70–71 and the following
descriptions to become familiar with the locations
and functions 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 54
for detailed instructions.
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.
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 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
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.
