To keep the belt sander belt centered on the platen, you adjust the

• A. top wheel
• B. rear roller
• C. table
• D. front roller

Answer: (D)

To keep the belt centered on the platen, you adjust the front roller because that roller directly governs the belt’s path as it wraps toward the platen. By tweaking the front roller’s alignment, you push the belt left or right so it sits evenly across the platen, ensuring even contact and wear. The top wheel mainly provides drive, not lateral positioning; the rear roller can affect overall tracking in some machines but isn’t the primary means for centering on the platen; and the table itself isn’t adjustable for belt tracking. After adjusting, verify by briefly running the belt to confirm it tracks centered.
