7. Install the Flexonic belt so that it travels around the motor pulley, but inside of the pulley on the front roller.
8. Reattach the front roller to the frame using the 2 screws removed in Step 5.
9. Use the Belt Installation Tool to install the belt on the front roller pulley
10. Move the belt in both directions for several revolutions so that the belt can settle into position.
11. The Flexonic drive belt is now set, the tension wheel set including the spring is discarded and not re-installed on the treadmill.
12. Re-install the motor cover.
