6. If the bearings were loose, the tightening procedure could change the arm positioning.
Test the positioning of the arm by rolling it along the beam. It should roll smoothly the
whole way and be parallel to the tabletop.
6.2 Aligning the Arm
When your Castle Assembly Table is set up or reassembled after relocation, the arm must be
aligned to ensure proper operation.
Note: This procedure requires two people.
1. If the arm is not already on the table, remove the stop bolt on one end of the top beam
and slide the assembled arm onto the table.
2. Re-insert the stop bolt.
3. Loosen the four bolts on the top bracket that hold the arm in place while someone holds
the bottom bracket firmly in place on the table.

6. Tighten the bolts in the upper bracket.
7. Test the positioning by rolling the arm along the beam. It should roll smoothly across the
entire work top.

functioning of the arm.
