Treadmills that are used regularly also require regular maintenance. The tread belts are subject to wear from being walked on and from rubbing against the treadmill deck. Likewise, the drive belt rubs against the moving parts inside the treadmill, and all of this wear increases when the belts are not lubricated regularly. Lubricating and waxing the treadmill will decrease the number of times you will need to replace the parts and increase the treadmill's overall lifespan.

    Lubricating the Tread Belt

  1. 1

    Check your treadmill's manual for any specific instructions. Certain treadmills may suggest a certain type of lubricant or require certain amounts.

  2. 2

    Check your treadmill's belt for signs of wear, such as cracks. If there are a lot of cracks, the belt may need to be replaced. If it looks all right, run your treadmill for a few minutes to warm it up. This will help spread the lubricant. After a few minutes, turn the treadmill off and unplug it.

  3. 3

    Slip one end of a clean towel underneath the belt that you normally walk on. Use a ruler to push the towel through to the other side while still grabbing one end. You may need to loosen the belt of the treadmill. Adjusting screws are usually located on either the front or back ends of the treadmill. In most cases, treadmills come with wrenches to adjust these, but if yours didn't, you will need to contact the manufacturer to find out what tool to use.

  4. 4

    Guide the towel back and forth underneath the belt to clear away any debris that might be underneath it.

  5. 5

    Put a few drops underneath and on top of the belt according to the treadmill's instructions. Use a cloth to rub the lubricant over the treadmill, but don't rub it all the way in or it will dry and not do its job.

  6. 6

    If you had to loosen the treadmill belt, retighten it, then run the treadmill on its lowest setting for a few minutes. The lubricant on the top of the belt will lubricate the treadmill deck and top of the belt, and the lubricant on the other side will lubricate the treadmill rollers.

    Lubricating the Drive Belt

  1. 1

    Make sure the treadmill is turned off and unplugged, then remove either the back or underside panel. The location of the panel will depend on your treadmill's model. Flip the treadmill on its side, and unscrew the screws holding the panel in place.

  2. 2

    Locate the drive belt. This belt will be thick and dark in colour. Inspect this belt for cracks and breaks to make sure it doesn't need to be replaced.

  3. 3

    Apply a few drops of lubricant on the drive belt. Spread it with a clean rag. Again, you don't want to rub it completely into the belt.

  4. 4

    Put the panel back on, and screw the screws back in. Reposition your treadmill so it is on its base again.

  5. 5

    Run your treadmill for a few minutes. The lubricant on the drive belt will spread across the moving parts inside the treadmill.

Tips and warnings

  • If you are not using lubricating wax, you will need to apply wax once the lubricant is dry. You can do this the same way that you applied the lubricant.
  • If your treadmill's manual doesn't specify which products are OK to use, you can purchase wax and lubricant designed for treadmills.
