NOTE:
Be sure to apply torque in two steps using a
crossing pattern. Failure to do so could distort the
face of the ram adapter.
4. Tighten the four hex nuts (A). Tighten in two
steps using a calibrated torque wrench. Tighten
initially to 25 foot-pounds, the tighten the four
hex nuts to a final torque of 50 foot-pound
Returning to Upright Position:
1. Check to make sure the mill head is square to
the worktable, by setting up a dial indicator in a
collet or with a magnetic base on the spindle
2. Put the spindle drive in neutral and rotate the
spindle 180 degrees (when rotating, raise the
indicator plunger to prevent it from dropping
into the table T-slots (Fig. 24)
3. The indicator should read the same in position
“C” and “D” (Fig. 24) of the table. If not, loosen
the four hex nuts (A of Fig. 22 ) and reposition
the mill head. . If the indicator does not read
the same in “E and “F” (Fig.24) loosen the nuts
“A” in Fig. 21 and reposition the mill head.

NOTE:
The lock bolts shown in Fig. 22, 23 are
threaded into T-nuts that travel in a circular
slot during head rotation. When rotating the
head, it is possible for these T-nuts to jam in
the slot preventing movement of head. If this
happens, gently rotate each lock bolt, start-
ing with the lower right, until you free up the
jammed T-nut. Then continue to rotate head
to desired position.

NOTE:
Always lock head firmly in place after tilt-
ing or rotating it. Unexpected movement
of head during operations could cause
damage to cutter or workpiece.
