Power Feed Controls
Use Figures 65–66 and the following
descriptions to become familiar with the locations
and functions of the power feed controls.
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 52
for detailed instructions.
ALWAYS make sure the spindle is completely
stopped BEFORE using the headstock control
levers to make changes. 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!
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.
Do not attempt to engage the feed selection
lever and the half nut lever at the same
time. The lathe is equipped with a protective
mechanism to prevent this, but the
mechanism can break if the levers are forced.
Depending on the combined configuration of
the headstock feed direction lever and the
apron feed direction knob, the actual direction
of power feed may be different from the
printed indicators on the machine!
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.
