Spindle Brake (B, Fig. 4)
It is located on the left side of the head. Move-in either direction to stop the spindle once the power has been turned off.
Quill Feed Handle (C, Fig. 4)
It is located on the right side of the head. Rotate counter-clockwise to lower spindle. The return spring will retract the spindle automatically once the handle is released.
Quill Lock (D, Fig. 5)
It is located on the right side of the head. Rotate the handle clockwise to lock the quill in the desired position. Rotate the handle counter-clockwise to release.
Micrometer Adjusting Nut (E, Fig. 4)
It is located on the front of the head. Used for setting specific spindle depth.
Manual Fine Feed (F, Fig. 4)
It is located on the left side of the head. Must engage fine feed (I, Fig. 5) for the hand wheel to function.
Quill Stop (G, Fig. 4)
This is located on the front of the head. Used in conjunction with a micrometre fine adjusting nut for a predetermined depth.
Reversing Switch (H, Fig. 5)
It is located on the left side of the head. Switches rotation of the spindle. For 3 Ph motor, there is an additional low and high-speed option.
Fine Feed Engagement (I, Fig. 5)

Longitudinal Movement (J, Fig. 6)
Handles located on opposite ends of the table. This controls the X-axis.
Cross Movement (K, Fig. 6)
Handle located directly in front of the machine. This controls the Y-axis.
Knee Handle (L, Fig. 6)
This raises the table up and down.
How Do You Change its Speeds?
- Unscrew two knobs (A, Fig. 4) and remove the belt cover.
- Loosen hex nut (A, Fig. 7).
- Take the tension off the belt by moving the handle (B, Fig. 7).
- Use the RPM chart to place the belt in the desired position.
- Place tension on the belt by moving the handle.

Installation layout
How Do You Position the RAM?
CAUTION!
Care should be taken to lock the RAM securely after setting.
Ram can be moved by loosening two handles (A, Fig. 8), and turning handle (B, Fig. 8) to the desired position.
Note: It is recommended that during heavy milling work, the head should be left as close to the face of the turret as possible to achieve maximum rigidity.
How Do You Make Adjustments to It?
Knee Gib Adjustment
(#53) Adjust the gib screw (#18) below the wiper on the left side of the knee for proper travel and to reduce excess play.
Note: When adjusting the gibs, always start with the knee. Adjust the saddle second, and adjust the table last.
Saddle Gib Adjustment
(#47) Adjust gib screw (#18) found on the right side front of the carriage for proper travel and excess play.
Table Gib Adjustment
(#45) Adjust gib screw (#18) found on the left side of the table toward the front of the carriage for proper travel and excess play.
Ram Wear Plate
(#10) Adjust two set screws (#19) found on the side of the ram for proper travel.
Head Alignment
The scales on the ram adapter and head rotation are guides only. Close tolerance work will require the use of a dial indicator to ensure the head is 90 to the table in the X-axis.
Longitudinal & Cross Feed Adjustment
If there is excessive backlash in the handle:
- Loosen hex socket head screw (#27).
- Turn feed screw nut (#26 or 29) to remove play.
- Tighten hex socket head screw.
Head Assembly
For your head assembly, you have:
How to Prepare The Site For This Mill?
CAUTION!
The Mill must be supported equally under all four corners. Failure to comply may cause the column to twist and put a bind in the bedways.
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 footprint of the mill.
How to Lubricate This Machine?
CAUTION!
Do not operate the mill before lubricating the machine fully. Failure to comply may cause damage to the machine.
Reference Fig. 3 for parts of the mill to lubricate:
A. Spindle Bearings – fill oil cup once daily with Mobil DTE Oil Light.
B. Oil Pump – Fill the reservoir as needed by removing the cap on top of the tank and filling it with Mobil Vactra Oil No. 2. Pump oil with the release handle once for every hour of operation. Way surfaces and lead screws are lubricated in this manner.
C. Knee Leadscrew – lubricate with Mobilith AW2 once a week.
Electrical Connections
WARNING! All electrical connections must be made by a qualified electrician! Failure to comply may cause serious injury!
Confirm that the power at the site matches the power requirements of the mill before connecting to the power source.
The mill must be properly grounded.
How Do You Lift This Mill?
WARNING
Keep people a safe distance away from the milling machine while it is being moved. Failure to comply may cause serious injury!
Lift the mill with appropriate-sized lifting straps. Follow the diagram in Fig. 2 for the proper position of the straps under the ram.
Note the position of the RAM and that the table has been moved against the column. Tighten the ram locking bolts (A, Fig. 2) before lifting.
Carefully lift the mill. Move into position over the anchor bolts. Lower the mill onto the anchor bolts. Check for level and secure with washers and anchor bolt nuts.
Check the mill for level with a machinist’s level placed on the table. The mill must be level back-to-front and side-to-side. Shim if necessary, but remember that the mill must be supported equally at all four corners. Check for level before tightening the anchor bolt nuts and after tightening them. Adjust as necessary.
How Do You Raise The Mill’s Head?
Remove handwheel (A, Fig. 1).
Loosen four cap nuts (B, Fig. 1) turn to unlock the head. Do not remove these nuts unless you are prepared to remove the head.
Use a 19mm socket and breaker bar on the adjusting nut (C, Fig. 1) to rotate the head.
Instructions on how to Unpack and Clean up
Finish removing the sides and top of the crate.
Leave the mill bolted to the skid until it is ready to be moved to its final location.
Clean all rust-protected surfaces with kerosene or a light solvent. Do not use gasoline, paint thinner, or lacquer thinner. These will damage painted surfaces.
Cover all machined surfaces with a film of light machine tool oil to inhibit rust.
Remove the wood block from below the knee.
