I had the same problem..the fix was easy. Remove the cover from the motor area, examine the belt(its on the right). My belt was simply loose. I took a wrench (1/2 or 9/16 I think)...loosened the bolt, wedged the motor so that the belt was tighter, and tightened the bolt. Volia. Cured...Good Luck.

This is caused by one of three problems. First and most likely, the walking belt is loose. To tighten the belt, start by locating the two bolts that adjust the rear roller (one on each side of the unit in the back). Run the unit at about 3 mph. Tighten the bolts a 1/4 turn at a time. Make sure that what you do to one side, you MUST do to the other side or the belt will get off center. After you tighten it 1/4 turn, check the belt to see if it is still slipping. If it is then tighten the belt 1/4 turn again. Continue until the belt does not slip, but do not tighten the bolts more than 2 full turns. If it takes more than 2 turns then something else is the problem. The second problem that it could be is the drive belt might be loose. To tighten the drive belt, start by removing the front cover. loosen the bolts around the motor then tighten the drive belt by tightening the motor adjuster bolt. Once the drive belt is tight, tighten the motor back down. The third problem that it could be is the walking belt could be worn and need to be replaced. Let me know if you have any questions.

To tighten up the running belt, you need to increase the tension, by adjusting the 'tension bolts'. There are two of them. They are located at the back foot of the treadmill. (kinda like where the back bumper would be, if it was a car). Little black bolts. One on each side, and they require a hex key. Clockwise to tighten. Good Luck!
