1. Place the GAINER GL-2000 Belt Pulley Alignment Tool on the pulley (A) by the motor side.
2. Measure the width deviation of the two pulleys and adjust the reference point of the alignment calibrators accordingly.
3. Position the three calibrators at the 3, 6, and 12 o'clock positions on Pulley (B).
4. Turn on the power and project the GL-2000 laser beam onto the calibration targets.
5. Inspect the circular 360° level and the laser position on the targets, then adjust the pulleys until proper alignment is achieved.
