How do you adjust the belt on a NordicTrack treadmill?

To adjust the belt on a NordicTrack treadmill, one first ensures that the treadmill is turned off and unplugged. With an Allen wrench, they locate the rear roller adjustment bolts at the end of the treadmill deck. By turning both bolts an equal quarter turn to the right, the belt tightens, while turning them to the left loosens it. It's important to make small adjustments and then check the alignment by plugging in and turning on the treadmill to observe the movement of the belt. If the belt is centered and at the correct tension, no further adjustments are needed. However, if the belt has shifted to one side, they adjust the bolt on that side accordingly—a right turn moves the belt to the left, a left turn moves it to the right—until it’s correctly aligned. After each adjustment, they must always verify the belt tension and tracking by running the treadmill at a slow speed to ensure safe and proper operation.
