How to Tighten Treadmill Belt?

Step 1: Unplug the Treadmill

Before you start tinkering with the treadmill, make sure you unplug the power cable from the outlet. This will prevent any accidental shocks while you work on tightening the belt. For extra safety, you can also remove the key if your machine is equipped with one.

Step 2: Locate the Adjustment Bolts

Most treadmills have two adjustment bolts located near either side of the running deck (the part where you actually run). The bolts are usually hidden behind covers that need to be removed before they can be accessed. You should also locate and loosen the idler roller bolt near one of the adjustment bolts before continuing.

Step 3: Tighten The Belt

Once all of the necessary screws and bolts have been loosened, use a long screwdriver to turn both adjustment bolts clockwise until they have been tightened completely. As you do this, be sure to keep an eye on how tight or loose your belt is becoming; if it’s too tight, it can damage both your machine and yourself during exercise sessions!
Step 4: Re-Adjust The Idler Roller Bolt Once you’ve achieved your desired level of belt tension, re-tighten the idler roller bolt onto its original position using a socket wrench or similar tool. After that’s done, replace all of the covers and plug in your machine again — et voilà! Your treadmill is now ready for use.


Tightening your treadmill belt shouldn’t take more than 10 minutes and requires minimal effort – but it’s an important step in keeping your machine running smooth and safe for users of all ages and abilities! If you ever find yourself having difficulty with any steps outlined above, please consult with a professional technician for assistance — not only will this help ensure that your machine stays safe and functional for years to come but it’ll also save time in troubleshooting down the road.
