This page explains how to adjust a treadmill belt to ensure that it is correctly aligned on the running board. An adjustment will be needed if the belt is not in the centre of the running board to avoid touching the sides of the footrests.
Adjusting the running belt
If the running belt is off centre, remove the safety key and UNPLUG THE POWER CORD.
If the running belt has shifted to the left (viewed from the back), use the 6mm hex key to turn the left idler roller screw clockwise ½ a turn; if the running belt has shifted to the right (viewed from the back), turn the right idler roller screw clockwise ½ a turn.
Then, plug in the power cord, insert the safety key and run the treadmill for a few minutes. Repeat until the running belt is centred.
Tightening of the running belt
If the running belt slips when walked on, first remove the key and UNPLUG THE POWER CORD.
Using the 6 mm hex key, turn both idler roller screws a ¼ of a turn clockwise at a time until you can lift each edge of the running belt 3 to 4 inches (8 to 10 cm) off the running board.
Be careful to keep the running belt centred. Then, plug in the power cord, insert the safety key, and carefully walk on the treadmill for a few minutes. Repeat until the running belt is sufficiently tightened.
Loosening the running belt
1. To loosen the running belt, first, remove the key and UNPLUG THE POWER CORD.
2. Then using the hex key, turn both idler roller screws a ¼ a turn counter clockwise at a time until you can lift each edge of the running belt 3 to 4 inches (8 to 10 cm) off the walking board. Be careful to keep the running belt centred.
3. Then, plug in the power cord, insert the safety key and run the treadmill for a few minutes.
4. Repeat until the running belt is properly tightened.
