   • Stretch the belt over the brush roll, ensuring it is properly seated in the designated groove.
6. Reinsert the Brush Roll
   • Align the brush roll with the designated slots on both sides of the vacuum.
   • Ensure the brush roll rotates freely within the belt.
7. Reattach or Adjust the Height Mechanism (If Applicable)
   • If a height adjustment rod or lever was disengaged, return it to its proper position.
   • Verify that the mechanism is properly seated and does not obstruct belt movement.
