slipping belt on Confidence GTR treadmill

qkcam

Hi I dont need anything fancy..just something lightweight that will let me keep walking inside when i need too. I also dont have a very big budget. found a confidence GTR treadmill for free but the current owner says belt is slipping. I can't seem to find anyplace that even sells parts for this. wondering also if it might work to convert it to a manual treadmill would that decrease the slippage? any thoughts and ideas are welcome. Thank you!
