- Remove Nozzle Guard (Diagram 1):
Unplug the vacuum. Turn the vacuum over. Locate and remove the nozzle guard. This typically involves unscrewing or unlatching it. For specific instructions on removing the nozzle guard, consult your vacuum cleaner's model-specific manual.
- Replace Belt on Motor Shaft (Diagram 2):
Carefully remove the old belt from the motor shaft and discard it. Place the new Style 10 belt onto the motor shaft. Ensure it is seated correctly.
- Replace Belt on End Cap (Diagram 3):
Position the new belt around the brush roll. For models with an end cap, ensure the belt is correctly placed within the end cap mechanism.
- Seat Brush Roll (Diagram 4):
With the belt properly positioned on both the motor shaft and the brush roll, carefully reinsert the brush roll into its housing. Ensure the brush roll spins freely and the belt is taut. Reattach the nozzle guard securely. The belt should be tight to ensure proper operation of the brush roll.
Maintenance
To ensure optimal performance of your Dirt Devil vacuum cleaner, it is recommended to replace the Style 10 vacuum belt every 3 to 6 months, or sooner if signs of wear, stretching, or breakage are observed. A worn belt can lead to reduced brush roll effectiveness and decreased cleaning performance.
Troubleshooting
- Brush Roll Not Spinning: If the brush roll is not spinning, the belt may be broken, stretched, or improperly installed. Unplug the vacuum and inspect the belt. Replace if necessary, following the installation instructions.
- Reduced Suction/Cleaning Performance: A worn or slipping belt can cause the brush roll to slow down, leading to poor cleaning. Replace the belt to restore optimal performance.
- Burning Smell: A burning smell often indicates a slipping or damaged belt. Immediately unplug the vacuum and inspect the belt. Replace any damaged belts.
