Power Feed - Grizzly G9249 Owner's Manual

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.

the power feed can lead to carriage or cross
slide crash that may permanently damage
