Proform belt tightening - size of allen wrench?
I have a Proform 545s treadmill that has a loose belt. I bought it used and need to tighten the belt. I know how to do it, but I need to know the size of the allen wrench because the one that came with it to the original owner didn't filter to me...the 'new' owner.
Thanks!
