CHAPTER 1 - INSTALLATION
UNCRATING
Carefully remove protective crating and skids so that the machine and parts are not marred,
scratched or impaired. In the event of damage having occurred during transit, communicate at once
with our representative and the transportation company making delivery.
SHORTAGES
Check shipment carefully against the itemized packing list which is included in the parts box. In
case of shortages, report them immediately to the representative from whom the machine was
purchased, indicating the parts not received which have been checked on the packing list.
CLEANING
Thoroughly clean protective coating from the machine with a suitable cleaning solution.
- WARNING -
DO NOT use gasoline or any other flammable cleaning agent to clean machine.
- NOTE -
Do not move the table, saddle, knee,
or any moveable part until all ways
have been well cleaned and lubricated.
1. After initial cleaning, move table, saddle and
knee in one direction by hand to limit stop.
2. Clean and lubricate the exposed ways.
3. Move each unit to the opposite limit stop,
and clean and lubricate the exposed ways.
4. Move each unit to the opposite stop once
more and similarly clean and lubricate the
exposed ways.
5. Loosen bolts to unlock the ram, and move it
forward and backward to the full length in or-
der to clean and lubricate.

INSTALLATION
If delivery of your machine is made with the milling head in an upside-down position, follow the
instructions below to prepare your machine for operation.
HANDLES
For shipping purposes, the hand cranks are inverted to face the machine. To reverse them,
engage the lock mechanism to the saddle and table. Using a (1-inch) wrench, remove the retaining
lead screw nut and install the hand cranks properly.
POSITIONING HEAD UPRIGHT
Loosen four locknuts “C”, Figure 1.3, and pull stop pin “A”, Figure 1.2, out to detent and rotate
head attachment using the swivel bolt “B”, Figure 1.3, in either direction until it has been moved within
approximately 20% of vertical. It is recommended supporting the head by hand to relieve the weight
on the swivel bolt, as a safety precaution, push the stop pin back in. Continue to raise the head
attachment to vertical position. Align the indicator on the head attachment with the ZERO line on the
ram adapter scale. Tighten all nuts first to 25 lb-ft torque in a diagonal sequence, then to 50 ft/lbs.
- NOTE -
Care should be taken to avoid excessive pressure since this will cause distortion in
the quill.
1. Lower knee approximately 6” (150mm).
2. Withdraw the safety pin on the left-hand side of ram adapter.
3. Loosen the four unit head mounting bolts.
4. Support unit head manually and use a spanner on swivel bolt to wind into upright position.
5. Press the safety pin back into the ram adapter after passing the 25°mark.
6. Tighten the four unit head mounting bolts first to 25 lb-ft in a diagonal sequence then to 50
lb-ft.

HANDLING
Lifting the Machine
- WARNING -
BE SURE to use proper sling when lifting. improper lifting could cause seri-
ous injury.
Note position of ram and table when lifting with sling. Machine should be lifted by placing a sling
under the ram as illustrated in Figure 1.4.

Tightening Sequence
Tighten bolts first to 25 lb-ft torque in a diagonal sequence as noted in Figure 1.5, then to 50 lb-ft.
Overtightening could cause bind in the quill movement.
Placing on Solid Foundation
When setting machine on a concrete foundation, it is advisable to use a little grout (thin mortar) to
take care of any unevenness in the concrete as well as to provide a solid foundation at all points.
When setting machine on a floor than has any surface irregularities, shims should be used to
correct this condition to the greatest extent possible.
- NOTE -
It is recommended that the machine be secured to the floor to prevent movement
or tipping due to off-center loading.

Before securing machine to floor by tightening
hold-down bolts, make certain that all four cor-
ners are making contact with the floor after ma-
chine is leveled. If above condition is not met, it is
possible to twist the column and but a bind into
ways.
Ideallyallmillingmachinesshould be boltedto
a concrete foundation. The machine should be
placed on a solid level floor with shims or
anti-vibration pads as shown in Figure 1.6 to
insure machine base is positioned evenly.
Leveling Machine
Set machine by leveling the work table
lengthwise and crosswise with a precision
instrument as shown in Figure 1.7.

MACHINE POWER SUPPLY
- WARNING -
MACHINE MUST be hooked up by a qualified electrician.
CONNECTING THE POWER SUPPLY
To connect the machine to the plant supply, have a qualified electrician proceed as follows:
1. Check required voltage against power supply to ensure that they are compatible.
2. Connect machine wiring to power supply making sure connection is in compliance with
safety regulations.
3. Check for correct spindle rotation. In the HIGH SPEED range, the spindle should rotate
clockwise when viewed from the top of the machine.
- NOTE -
Drum switch and hi-neutral-lo lever must be in hi range when checking spindle ro-
tation.

INITIAL SETTINGS
HEAD CONTROLS
Alignment of Head for Fine Work
For precision boring or work of that nature, where it is necessary to have the head perfectly square
with the table, use method described below. To set head perfectly square with table, adjust ram
adapter through vertical adjusting worm shaft with ram adapter on ram. Loosen four locknuts but
leave drag on same for fine adjustment. To square head to table in the longitudinal axis, mount
indicator as shown in Figure 1.9. For general milling use, graduations provided on the head are close
enough.
Tightening Sequence
Tighten the four head locknuts in a diagonal order as previously described on Page 1-4. Tighten
the three ram locking bolts to 50 lb-ft.
Lubrication
Do not operate machine until properly lubricated.
