4. Seek professional maintenance help: If the above methods can't solve the problem, or you are not sure how to carry out maintenance, it is recommended to seek professional maintenance help. You can contact the treadmill manufacturer or the local fitness equipment maintenance center, and their experienced professional technicians can provide you with a solution.
