    Why is my NordicTrack NTL12309.0 Treadmill walking belt off-center or slips when walked on?
    • S

      If the walking belt of your NordicTrack Treadmill is off-center or slips, here’s what to do: * For an off-center belt: Unplug the treadmill and remove the key. If the belt is shifted left, turn the left rear roller bolt clockwise 1/2 turn. If shifted right, turn it counterclockwise 1/2 turn. Plug the treadmill back in, insert the key, and run it for a few minutes. Repeat until centered. * For a slipping belt: Unplug the treadmill and remove the key. Turn both rear roller bolts clockwise 1/4 turn. Ensure the belt isn't too tight—you should be able to lift each edge 3 to 4 inches. Plug the treadmill back in, insert the key, and carefully walk on it for a few minutes. Repeat until properly tightened.
