Feed Rate Chart - Grizzly G4002 Owner's Manual

figure 16. Feed rate selector levers.
important:
do not force any selection lever on the machine.
if the lever will not engage, rotate the chuck by
hand while keeping light pressure on the selector.
As the chuck rotates, it aligns the gears and the
selector will engage.
to change the position of the feed selector, pull
the knurled handle. this disengages a pin which
is inserted into a selection hole. position the lever
in the down position and slide to the right or left
until it is positioned below the desired selection
hole. raise the lever with one hand while pulling
the handle with the other. the pin at the end of the
lever should align with the selection hole. if it does
not, rotate the feed rod or chuck by hand while
maintaining gentle pressure on the lever.

feed Rate chart

to perform a longitudinal cut in inches, use the
bottom portion of the chart. if the desired feed
rate is 0.0062"/revolution, look at the longitudinal
ranges. According to the chart we would put the
left-hand lever in the "C" position and the right-
hand lever in the "4" position. Metric calculations
would be done the same way. to perform a cross
feed cut with a feed rate of 0.0013" move the left-
hand lever to the "d" position and the right-hand
lever to the "1" position.
please note that when either of the two selector
levers are left in the down position, the drive train
after this point is in neutral.

feed Lever - longitudinal and cross slide pow-
ered motions are controlled by the feed lever. the
lever pivots through two stops which require mov-
ing the lever left and right as well as up and down.
Moving this lever upward activates the automatic
longitudinal feed. Moving the lever down activates
the cross slide. see figure 18.
