I also have a TX 4.9 hp treadmill. If you call their customer service line they will email you the instructions. That number is (800)526-0244. They emailed me the instructions within 15 minutes of my call. Their website is www.sportcraft.com. I believe this also has an email address for customer service. They were very helpful. Good luck!!!
