following parts list to make sure all parts are intact.
Missing parts, if any, should be reported to your
distributor. Read the instruction manual thoroughly
for assembly, maintenance and safety instructions.

Powerfeed and/or DRO, be sure to consult the
separate instruction materials that accompany
them.

5.2 Preparing the mill for service
1. Remove any crating which may be covering the
machine on the pallet.
2. Remove accessory items from pallet or
machine table. Compare items with section 5.1 .
3. Check lifting ring on ram to be certain it is tight.
4. Check tightness of lock handles on ram (C and
E, Figure 9-3) to be certain ram is locked tight.
5. Remove nuts and bolts which secure machine
to pallet.
6. Center an overhead crane or other suitable
overhead lifting device and sling arrangement
over the lifting ring.
Note: This machine weighs over 3000 pounds
– be certain 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 will tip
forward. If you wish, you can minimize this
tipping by rigging a support sling over front of
machine. Be careful when doing this, to prevent
sling from damaging any components on front
of machine. Be sure to steady mill to prevent it
from spinning.
7. Lift machine off pallet no higher than necessary
to clear hold-down hardware, then pull pallet out
of the way. Do NOT get hands or feet
underneath machine when removing pallet!
8. Put machine base over hold-down system
where machine will be spotted. Anchor bolts
(not provided) of sufficient size and length must
be fastened to the floor according to footprint of
mill. See Figure 4-1.
Note: Figure 4-1 shows maximum dimensions
of machines with table, ram, etc., fully extended
in all possible directions. When spotting
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.
