Identify the Correct TensionThe correct belt tension varies by manufacturer and model, so consult your treadmill’s manual or contact the manufacturer to determine the appropriate tension for your machine.
Power Off the MachineBefore adjusting the belt tension, make sure the machine is turned off and unplugged to avoid any accidents.
Locate the Adjustment BoltsMost treadmills have two adjustment bolts at the rear of the machine near the belt.
Loosen the Adjustment BoltsUse an appropriate tool to loosen the adjustment bolts, but be careful not to over-tighten or damage them.
Adjust the Belt TensionUse a Tension Gauge for a Treadmill to measure the belt tension, and adjust the bolts as needed to achieve the correct tension.
Re-Tighten the Adjustment BoltsOnce the belt tension has been adjusted, tighten the adjustment bolts securely.
Test the Belt TensionPower on the machine and test the belt tension to ensure that it’s properly adjusted.
Follow the Manufacturer’s GuidelinesAlways follow the manufacturer’s instructions for proper use, maintenance, and care of your treadmill. This can help prevent damage to the machine and ensure your safety during use.

Understanding Treadmill Belt Tension

Before you start adjusting your treadmill belt tension, it’s important to understand how the belt tension affects your workout. The belt tension determines how much resistance the belt provides when you walk or run on it. A loose belt provides less resistance and makes it easier to walk or run, while a tight belt provides more resistance and makes it harder to walk or run.

If the belt is too loose, it can cause the belt to slip, which can be dangerous and cause damage to the machine. A loose belt can also cause the motor to overheat, as it has to work harder to keep the belt moving. Conversely, if the belt is too tight, it can cause the motor to overheat, and it can also cause excessive wear and tear on the other components of the machine.

  • Tension adjustment tool (if provided with the treadmill)
  • Owner’s manual

Steps for Adjusting Treadmill Belt Tension

Power off the Treadmill

Before you start any maintenance work on your treadmill, you should always unplug the machine to avoid any risk of electrocution.

Locate the Tension Adjustment Bolts

The location of the tension adjustment bolts varies depending on the treadmill model. However, in most cases, the bolts are located at the rear of the treadmill, near the rollers. Refer to your owner’s manual to locate the bolts on your treadmill.

Check the Tension of the Belt

To check the tension of the belt, you should be able to lift the belt up about 2-3 inches from the center of the belt. If the belt is too loose, you will be able to lift it more than 3 inches, and if it’s too tight, you won’t be able to lift it at all.

Loosen the Bolts

Using the Allen wrench, loosen the bolts on the left and right sides of the treadmill, where the belt meets the deck. Turn the wrench counterclockwise to loosen the bolts.

Adjust the Tension

Using the tension adjustment tool (if provided), turn the bolts clockwise to tighten the belt or counterclockwise to loosen the belt. Be sure to turn the bolts evenly on both sides to maintain the belt’s center.

Retest the Tension

After adjusting the belt tension, check the tension again by lifting the belt up from the center. The ideal tension is when you can lift the belt up about 2-3 inches.

Tighten the Bolts

Once you have achieved the desired tension, tighten the bolts on both sides of the treadmill deck using the Allen wrench. Turn the wrench clockwise to tighten the bolts.

Plug in the Treadmill and Test

After tightening the bolts, plug in the treadmill and test it to ensure that the belt is running smoothly and that the tension is correct.

Additional Tips for Maintaining Treadmill Belt Tension

Maintaining the correct tension on your treadmill belt is crucial for ensuring a safe and effective workout. Over time, the tension may loosen or become too tight, which can affect the performance of the machine and increase the risk of injury. In addition to the steps outlined in our previous post, here are some additional tips for maintaining treadmill belt tension:

Check the alignment of the belt:

If the belt is not aligned properly, it can cause uneven wear and tear and affect the tension. To check the alignment, turn off the treadmill and remove the motor cover. Place a straight edge across the width of the belt and check if it’s aligned with the edges of the deck. If it’s not aligned, you may need to adjust the rear roller or the front roller.

Lubricate the belt:

A dry or worn-out belt can cause the tension to decrease. Regular lubrication can help to maintain the tension and prevent premature wear and tear. Be sure to use the recommended lubricant for your specific treadmill model.

Replace worn-out parts:

If the tension is consistently low or the belt is slipping, it may be time to replace worn-out parts such as the drive belt or the motor. Consult your treadmill manual or a professional technician to determine which parts need replacement.

Use the correct walking or running technique:

Poor technique can cause unnecessary stress on the belt and affect the tension. Make sure to keep your feet centered on the belt, avoid overstriding, and maintain a consistent speed and incline throughout your workout.

By following these additional tips, you can help maintain the correct tension on your treadmill belt and prolong the life of your machine. Remember to always consult your treadmill manual or a professional technician if you have any concerns or issues with your treadmill.
