1.Insert the 6 mm inner hexagonal wrench into the adjusting screw on the left side of the running belt and rotate the wrench clockwise for 1/4 turns to adjust the rear roller to tighten the running belt.

2.Repeat step 1 to adjust the right screw. It must be determined that the adjustment screw rotates the same distance so that the rear roller is adjusted parallel to the frame.

3.Repeat steps 1 and 2 until the running belt does not slip.

Note: The running belt can’t be adjusted too tightly, which will break the running belt and increase the pressure of the front and rear rollers, causing problems such as roller bearing damage and abnormal noise. If you want to reduce the tension of the running belt, turn the wrench counterclockwise.

Note that the left and right sides are rotated to the same distance.

1.Move the treadmill to no-load operation and adjust the speed to 3.7MPH .

2.Observe the distance from the running belt to the left and right border. If left deviation, use inner hexagonal wrench, rotate the left 1/4 screw clockwise. If right deviation, use inner hexagonal wrench and turn the 1/4 screw on the right side clockwise. If the running belt is still not in the middle, repeat the above action until it is adjusted to the middle.

3.After adjusting the running belt to the middle, adjust the speed to 6.2MPH and observe the deviation of the running belt and whether there is slipping during running. If there is a deviation, repeat the running step.

4.warning! Do not over tighten the rollers! This will cause permanent bearing damage. If the above steps are not effective, you need to tighten the running belt again.
