u/Left-Box1415

I was told that I should give it lubricant and then make sure that the belt is running evenly but I’m not sure if this belt is too loose since it runs evenly in the back but not evenly in the front and when I get on the walking pad, it pulls all the way to the right and I immediately get off because I’m scared I’ll damage the belt. Heard it could also be the floor? But not sure how much so? Thoughts?
