The belt on my treadmill seems to gravitate to one side of the machine and rubs along the side. It's causing small black particles of the belt to deposit on the floor beneath the machine. How can I keep this from happening? It' s Pro-Form PFTL-6251

The side the belt is riding to is a little loose.
Your treadmill may have come with an allen key for this.
at the rear of your treadmill there are 2 adjustment bolts.
Right and left on your roller. Run you treadmill at 3 mph. Turn the bolt 1/4 turn to tighten, until your belt goes back to center.
I also have a video on this at www.mindbites.com/person/214-Mark
