5. Instrucciones de funcionamiento

The auger shaft assembly operates automatically as part of your pellet stove's fuel delivery system. Once installed, its function is to rotate and convey pellets from the hopper into the burn pot at a controlled rate, as dictated by the stove's control board. No direct user operation of the auger shaft itself is required beyond ensuring proper installation.

6. Mantenimiento

Regular inspection of the auger shaft assembly can help identify potential issues before they lead to stove malfunction. Pay attention to any unusual noises during operation.

• Inspección visual: Periodically inspect the auger shaft for any signs of wear, bending, or damage. Ensure the helical flighting is intact and free of obstructions.
• Comprobación del cojinete: Listen for any abnormal noises from the auger area. An intermittent squeak or high-pitched noise when the drive motor turns, especially under load, often indicates wear in the auger shaft bearing. Since this assembly includes an integrated bearing, replacement of the entire unit is typically required if the bearing fails.
• Limpieza: Ensure the area around the auger shaft is free from excessive sawdust or pellet debris, which can impede its movement.
