How to Fix a Jerky Treadmill
1. Check and Adjust Belt Alignment
- Unplug the treadmill and remove the motor cover.
- Locate the belt adjustment bolts on either side of the treadmill frame.
- Use a wrench to tighten or loosen the bolts to align the belt in the center of the deck.
- Ensure that the belt is taut but not too tight.
2. Tighten the Belt
- If the belt is loose, it can slip and cause jerkiness.

3. Inspect and Repair Motor and Controller
- If the motor or controller is faulty, it may need to be replaced.
- Contact a qualified technician for professional assistance in this case.
4. Lubricate the Treadmill
- Lack of lubrication can increase friction and cause jerkiness.
- Apply a thin layer of silicone-based lubricant to the belt, rollers, and any other moving parts.
- Follow the manufacturer’s instructions for lubrication.
5. Inspect and Replace Damaged Components
