I have a proform 785 (model number 78570) treadmill. The belt has a tear in it and I am unsure how to go about getting it fixed. Where do I buy a belt online and is it hard to replace? Are there online instructions that I can follow? Is it better to get a technician to do it and how would I find one to do it? Any help would be so great!
