7 or 8 years ago I bought my pro form 830QT. I never serviced it or lubricated it, unfortunately. Now, when walking at 2.8-3.5 it slips or catches and I have to hold on to keep from falling off. At 3.5 and higher it's okay. Does this sound like I should lubricate the belt, replace the belt or motor or have I ruined it? Everyone is shocked it has lasted this long without upkeep. Any advice would be appreciated.
