If you encounter problems with the treadmill belt, you do not have to call a specialist. 

With a little skill, you can solve the problem on your own. Try the following steps:

  • Remove the engine cover, but be careful as there are electronic parts inside.

  • Set the speed of the treadmill to approx. 3 km / h and stand with your feet on the side rails. When the belt is running, put one foot on the belt to stop it. Hold on to the handrail.

  • Then stops the treadmill and motor.

  • If the treadmill stops and the front roller continues to turn, this is a sign that the treadmill belt is too loose or worn out . It must be replaced.

  • If you readjust the tension of the treadmill belt, make sure that it is not too tight afterward. Tightening too much on the treadmill belt is just harmful .

  • If the front roller stops rotating and the pulley on the roller continues to rotate; then , this is a sign that the front roller needs to be replaced or the pulley needs to be fixed better.

  • Stopping the belts and the pulley. The engine continues to turn and the drive belt must either be tightened or replaced.
