you do not have to remove the belt. If you put the treadmill to its folded position you can unbolt the side strips which will slide off. You then lower then platform and using an allen key unbolt the running board which will then slide out from the side

Hi John, I'm afraid I haven't got an answer for you yet as I'm just about to start stripping mine down. My running board has suddenly developed a huge dip under the belt. Have you discovered where I can get a spare? I'll get back to you once I've discovered how to get the belt off but in the mean time, I would be grateful if you would post here any information you have on spares Cheers, Ron
