Hello, my name is***** to Justanswer! Give me just a few minutes to look up some specifics, I'm working on this now.
Do you still need help with this?*This is an inquiry to see if you still need help. I'm here to help when you're ready. Due to the nature of the problem, it may take a few tries back and forth before we finish the troubleshooting and fix the problem. First, try unplugging it from power, or remove the battery for 5 minutes. Return the power, and tell me if you see any improvement.
When you say it's slipping, do you mean when you step on it, it doesn't move as fast as it should? Or is it slipping off to the side?
Ok, that sounds like a loose belt. Until the belt gets warmed up, it slips. Click here. Use the hex key to tighten the belt. This will be a very minor adjustment, and make sure you tighten both of them equally. Pay attention to the orientation of the hex key so you know where to turn each of them. Do this a little bit, try it, and repeat if necessary. Do it a little bit at a time, and the slipping should go away.
