Arm to Column Adjustment

If you can move the end of the radial arm up and down when the arm is unlocked, adjust as directed below:

a.Remove two (2) screws from rear cover plate. Tighten evenly top two 3/8-16 bolts until the play is removed and the arm will still move side to side freely. There should be no vertical or horizontal movement in the arm when miter/arm lock is locked and unlocked.

b.Bottom two nuts should be snugged evenly, but not nearly as tight as top two bolts.

c.Re-install Rear Cover Plate.

Adjusting Column Tube in Column Support

This adjustment will remove any looseness between the column tube and column sup- port while serving two purposes:

To insure accurate cuts; and

To allow the column tube to raise and lower smoothly.

Note: The following adjustment is very critical. All future alignment procedures rely on this adjustment being performed correctly. All looseness must be removed.

This section is set up in two sections: Alignment checks and adjustments. It is very important that the column tube and the inside of the column support are coated with a film of uncontaminated lubricant.

Alignment Checks

Two checks are required, these are adjusted at the factory, but may have shifted during shipment.

1.Index and lock arm at 0° Miter.

2.Vertical Alignment Check:

The two piece column support needs to be compressed by tightening the black and sil- ver screws to properly control the movement of the column tube. Precise alignment is done only by tightening or loosening the sil- ver 5/16-18 screws in combination with the brass set screw. Push up slightly on the end of the arm. Look for a noticeable movement between the column tube and the column support.
