1. Turn off the power to the machine

2. Check that they are on the same plane
Adjust the X dimension so that it is as close to 0 (zero) as possible. Place a straight edge against the side of the pulley and make sure that the pair of pulleys are on the same plane.

3. Reduce the distance between shafts
Loosen the bolts on the slide base or similar parts, and reduce the distance between shafts until the belt can be installed without force.

4. Apply tension to the belt
Align the teeth of the belt with the grooves of the pulley, and slowly pull the slide base or similar parts to apply tension to the belt. Because the belt is slightly shorter when there is no tension, the belt and pulley may not be fully engaged on pulleys with a large number of teeth. Slowly pull to ensure there are no areas where the belt and pulley are not properly meshed.

5. Pull the belt to the specified tension
Tension the belt so that the deflection load when pressing the center of the belt span (the part of the belt not in contact with the pulley) by a specified amount (16/1000 of the span length) matches the value calculated by the above formula.

6. Alignment Readjustment
With the belt tensioned, use a straight edge again to check the alignment. If there is any misalignment, remove the belt and readjust.
Especially in cases with a bearing on only one side, the shaft may deflect during operation, causing the belt to shift toward the side opposite the bearing. In this case, please adjust the parallelism of the shaft in advance by the amount of deflection.
7. Secure the slide base and other components firmly to prevent any movement.
8. Engagement check
1. Usage conditions for the tension pulley
Use the tension pulley only in cases where it is functionally unavoidable as described below.
· When used with fixed shaft spacing
If tension adjustment cannot be made by changing the distance between shafts, add a tension pulley to adjust the tension.
· When the gear ratio is large and you want to increase the number of engaged teeth on the small pulley
If the gear ratio is large and the number of engaged teeth on the small pulley becomes too low, add a tension pulley to increase the number of engaged teeth.
2. Tension pulley mounting
Adjust the alignment of the tension pulley accurately. Also, attach it to the slack side during operation.

· Inner tension pulley
When using a tension pulley from the inside, use a pulley diameter equal to or greater than the minimum pulley diameter specified in the catalog.

· Outside tension pulley
When using a tension pulley on the outside, use a pulley diameter at least 20% larger than the minimum pulley diameter specified in the catalog.

Tooth rubber / tooth tip / tooth fabric (reinforcing fabric) / tooth root surface / tooth surface / core wire

When the tooth fabric is worn and the rubber or core wire is exposed / when cracks appear in the back rubber of the belt due to increased hardness, etc. / when crazing occurs at the tooth root of the belt / when the side of the belt is damaged due to wear / tooth breakage / back wear / core wire breakage
Please perform a test run of the belt for several minutes and check the following items. If the following phenomena occur, please take appropriate measures.
Never bring your hands or body close to the pulley or belt while operating. Also, always make sure the belt has come to a complete stop and turn off the power before performing inspections or maintenance.
For daily maintenance of the belt, please pay attention to the following items.
Please check all of the above during inspection.
