Why is my Sunny Health & Fitness SF-T1407 making noise?

If your Sunny Health & Fitness Treadmill is making noise, it could be due to loose hardware, such as nuts, bolts, or screws. Inspect all hardware and tighten as needed. Another possible cause is that the running belt and board are not lubricated. Make sure you lubricate the running belt and board.
