Power feed
the rotating feed rod provides powered move-
ment of the carriage or the cross slide. the car-
riage moves left or right along the spindle center
line, and the cross slide moves in or out across
the spindle center line.
Note: Using the leadscrew for powered movement
of the carriage is discussed in the
Threading sub-
section starting on Page 40.
NOTICE
High feed rates combined with high spindle
speeds results in a rapidly moving carriage
or cross slide. Pay close attention to the
feed rate you have chosen and keep your
hand poised over the feed change lever.
failure to fully understand how to operate
the power feed can lead to carriage or cross
slide crash that may permanently damage
the machine.

1. use the spindle direction lever to turn the
spindle OFF, then allow the spindle to com-
pletely stop before making gear changes.

5. use the spindle direction lever to start the
spindle rotation.
6. return the feed rod/leadscrew lever to the
center position to disengage the power feed
from the feed rod.
2. Move the feed direction lever for the desired
feed rod rotation direction and carriage/cross
slide movement.

rotation is reversed.
NOTICE
Never engage the half-nut with the leadscrew
when using the feed rod for carriage or
cross slide movement. failure to follow
this instruction will lead to permanent dam-
