Treadmills are complex machines made up of mechanical elements, like belts, motors and electronic components. Just like a car, there will be times when things go wrong and the machine may signal this to you with a squeaking noise. If your treadmill is squeaking, it can be caused by several factors and generally signals the need some extra care.
Meaning of Squeaking
A squeaking treadmill can indicate one of many things. It can mean your belt needs lubrication or isn't level in its current position. In addition, it may signal that your walking belt needs adjustment. Squeaking can also indicate improper assembly or loose parts.
Tips for Repair
Before making any alterations, make sure your treadmill is sitting on a flat, level surface. Using your manual for guidance, lubricate the belt as directed, making sure the treadmill is unplugged. If those two fixes haven't solved the problem, it is likely a more serious issue and you may need to call your treadmill manufacturer for support and to connect with a professional that can help you fix the issue.
