1. Gather the necessary tools: You'll need a laser alignment system, which typically consists of a laser transmitter and a detector unit. Make sure the equipment is calibrated and in good working condition.

2. Prepare the workspace: Clear the area around the machines and remove any obstacles that may interfere with the alignment process. Ensure the machines are securely mounted and their foundations are stable.

3. Mount the laser transmitter: Attach the laser transmitter unit to the stationary machine's shaft or coupling. Make sure it's securely fastened and aligned with the rotational axis.

4. Mount the detector unit: Attach the detector unit to the movable machine's shaft or coupling. Again, ensure it's securely fastened and aligned with the rotational axis.

5. Establish the measuring reference: Determine the desired alignment tolerances and select a suitable measuring reference. This could be a particular point on the machines, such as a coupling face or a shaft centerline.

6. Take initial measurements: Start by measuring the misalignment between the two shafts. Activate the laser alignment system and align the laser beam with the detector unit. Record the initial readings provided by the system.

7. Make adjustments: Based on the initial measurements, identify the required adjustments. These adjustments typically involve moving the movable machine horizontally and vertically to achieve the desired alignment. Consult the machine manufacturer's guidelines for specific adjustment procedures.

8. Re-measure and iterate: After making adjustments, re-measure the alignment using the laser alignment system. Check the readings and compare them to the desired tolerances. If further adjustments are needed, repeat the process until the alignment falls within acceptable limits.

9. Finalize the alignment: Once the alignment readings meet the desired tolerances, lock down the machine's position by tightening the fasteners and securing the mounting. Double-check the alignment one last time to ensure it remains within the acceptable range.

10. Document the alignment: Record the final alignment measurements, including any adjustments made and the achieved alignment tolerances. This documentation will serve as a reference for future maintenance and troubleshooting.

Note: The above steps provide a general outline for performing shaft alignment using laser alignment tools. It's essential to consult the specific instructions and guidelines provided by the laser alignment system manufacturer for accurate and reliable results.
