Works for my Xterra Treadmill
I recently bought a used treadmill from a friend of the family. I noticed that the belt was slipping some. I looked up some videos on YouTube on how to care for your treadmill. The guy recommended some treadmill lubricant first. If that didn't work, then tighten each side of the treadmill one half turn. I tried the lubricant as he suggested and it helped some, but it still slipped. So, I used this wrench and did one half turn on each side. No more slipping. I'm sure you could buy an Allen wrench of this size that will work, but I wanted one that I could pass on to the next owner if I ever decide to sell it later.

La clé fonctionne à merveille sur mon tapis de course ProForm. Par contre cher pour un petit morceau de ferraille.
