Aligning the Arm
When the machine is set up or reassembled after relocation, the arm must be aligned to ensure proper
operation. This procedure requires two people.
SOLUTION STEPS:
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 in the top bracket that hold the arm in place while someone holds the bottom
bracket firmly in place on the table.
4. Do not loosen the bottom bracket bolts.
5. Adjust the arm in the upper bracket until the desired position is reached.
6. Tighten the bolts in the upper bracket.
7. Test the positioning by rolling the arm along the beam. It should roll smoothly the whole way.
8. This is a trial and error procedure and you may need to repeat steps 3 through 7 until the right
position is found.
