Castle AT-8 OB - Manual (Page 16)

3.4 Open Back Beam Installation
1. Locate the two yellow brackets. Begin by placing the two yellow beam brackets on the
end of the top beam of the table. The yellow brackets are left and right hand. Tighten
set screws to secure in place. Slide the top beam through yellow bracket on one side of
the table. Slide it just too far to one side so you may slide the bracket on in the next
step.
2. Put on the yellow arm top bracket with the “Castle” facing the front of the table.
3. Next slide the beam through other support bracket and tighten set screws. Make sure
the top beam is evenly spaced through the yellow bracket.
3.5 Arm Installation
1. Attach the arm bracket to the aluminum beam using
the 5/16-18x5/8 HHCS bolts [F51638] and 5/16-18 T-
nuts [F51698] supplied.
2. Position the clamp arm onto the frame from the right
side.
3. The length of the arm may need to be adjusted at the upper arm bracket.
4. Square the arm vertically by loosening 3 of the 4
bolts and drawing the arm parallel with the left
fence.
5. Slide the top bracket to achieve proper lower bearing adjustment.
