8.3 Site preparation
The mill must be placed on an even surface and
bolted to the floor. Anchor bolts of sufficient size
and length must be fastened to the floor according
to the mill’s footprint. See the site installation
diagram in Figure 1.
When spotting the machine be certain to leave
room not only for the machine itself, but also for
operator clearance and clearance for workers
servicing the machine, and any unusual sizes of
workpieces that might extend off the machine’s
table.
8.4 Lifting the mill
Finish removing the sides of the crate. Leave mill
bolted to pallet until ready to move to its final
location.
The preferred method for lifting mill is with a hook
through the lifting ring screwed into the tapped hole
atop the ram. (
Note : If your mill came with a top-
mounted DRO, remove DRO from hole to install
lifting ring. Reinstall DRO after machine has been
positioned.)
Check the lifting ring on the ram to be certain it
is tight.
Check the tightness of the lock handles on the
ram (A, Figure 4) to be certain the ram is tightly
locked.
Steady the mill to prevent it from spinning.
An alternative method for lifting the mill is with a
sling. Follow diagram in Figure 4 for proper position
of sling under ram. Note position of ram and that
table has been moved against column. Tighten ram
locking bolts (A, Figure 4) before lifting.

1. Remove the nuts and/or bolts, which secure
the machine to the pallet.
2. Center an overhead crane or other suitable
overhead lifting device and sling arrangement
over the lifting ring.
Note: This machine weighs over 2800 pounds.
Be certain the lifting arrangement is new or in
excellent condition and has a safety factor that
will account for age, difficulties in lifting, etc.
When lifting using the ring, the machine may
tend to tip forward. If you wish, you can
minimize this tipping by rigging a support sling
over the front of the machine. Be careful when
doing this, to prevent the sling from damaging
any components on the front of the machine.
Be sure to steady the mill to prevent it from
spinning.
3. Lift the machine off the pallet no higher than
necessary to clear the hold-down hardware,
then pull the pallet out of the way. Do NOT get
hands or feet underneath the machine when
removing the pallet.
4. Lower the mill over the anchor bolts. Level the
machine using shims under the corners
needing them. The machinist’s level used for
leveling should be placed on the table. The
table is the reference surface for both side-to-
side and fore-and-aft leveling. Be certain you
get it level in BOTH directions.
Mill must be supported
equally under all four corners. Failure to
comply may cause the column to twist and
put a bind in the table ways.
5. When the machine is level, secure the base to
the anchoring system.
8.5 Completing assembly
Before attempting to raise mill
head, familiarize yourself with instructions in
section 12.5 , for procedures to safely raise and
set up the mill head.
1. Loosen the four hexagonal nuts (see A, Figure
9) about one-quarter (1/4) turn each counter-
clockwise, just enough to allow rotation of the
head.
2. Apply upward pressure on motor by hand to
relieve pressure on worm mechanism, and use
supplied wrench to turn worm nut (B, Figure 8)
and raise head to upright position.
3. Tighten nuts (A, Figure 9); not torqued at this
time, just snug. Before operating mill, follow
procedures in section 12.5 to verify angle
settings and properly tighten the four nuts.
