When the resistance setting changes, the motor will be heard. To prevent damage to the motor, do not pull any of the cables while the resistance setting is changing. If the motor has difficulty adjusting the resistance level and no cable is being pulled, there may be too much tension on the Upper Cable (110). Adjust the tension as described below. To decrease the tension on the Upper Cable (110), turn the two 3/8” x 38mm Tension Screws (106) twice, counterclockwise. Select the desired resistance setting. Repeat this step if necessary.
