Make sure you are using a single-outlet surge suppressor that meets the required specifications. If the walking belt is too tight, unplug the treadmill and remove the key. Loosen the belt by turning both idler roller bolts counterclockwise 1/4 of a turn. The belt should allow you to lift each edge 3 to 4 inches off the platform when properly tightened. Plug the treadmill back in, insert the key, and test. Repeat adjustments as needed.
