To change the re-directional sprockets, please proceed as follows:
  1. Disconnect the electrical and pneumatic supply of the entire conveyor system and secure against reconnection.
  2. Turn the fan of the drive motor in the direction of flow to drive the conveyor manually until a master link is visible (zinced).
  3. Remove the clear front cover of the drive station and the steel plate above the clear front cover.
  4. Release the chain tensioner. Lock it in that position with an adequate device.
  5. Open the chain at the master link.
  6. Unbolt the re-directional sprockets.
  7. For installation please proceed in reverse order.
    Pay attention to the correct flow of the chain and install the new re-directional sprockets with locking washers.
  8. Install and check all bolts to be tightened.
  9. Re-tension the chain and reset the chain tensioner.
  10. Reinstall the clear front cover and the metal plate above.
  11. Run the conveyor system and check the tension of the chain at the chain tensioner. If the tensioner is almost at its far end, the chain has to be shortened by another chain link
  12. Check the chain tension after two hours of operation again.
