Why Is It Important To Adjust Your Treadmill Belt

If you’ve ever been on a treadmill, you know that the belt can sometimes slip. This usually happens when the belt is loose or not adjusted properly. If the belt slips, it can cause you to trip and fall, leading to serious injury.

Therefore, adjusting the treadmill belt is very important before you start using it. Here’s how to do it:


Make sure the belt is tight enough. You should be able to fit two fingers under the belt in the center of the deck. If you can’t, the belt is too loose and needs to be tightened.


Adjust the alignment of the belt. The best way to do this is to place your foot in the middle of the belt and move it to one side until it is under your foot.


Make sure the deck is level. You can do this by placing a level on top of the deck and seeing if it is level from front to back and side to side. If not, you will need to adjust the leveling screw until it is level.

After doing all this, you are ready to start using your treadmill! Just be sure to check the belt regularly to make sure it’s tight and properly aligned.

Signs Your Treadmill Belt Needs Adjustment

If your treadmill belt is slipping, it’s time for an adjustment. 

Here are five signs that your treadmill belt needs adjusting:

1. The belt slips when you walk or run on it.

2. The belt makes noise when you walk or run on it.

3. The belt seems loose when you walk or run on it.

4. The belt tracking is off, meaning the belt is not centered on the platform.

5. You notice uneven wear on the belt.

Required Tools For Adjusting Treadmill Belt

If the treadmill belt is too loose, it can cause the machine to vibrate and make noise. The belt can wear out the motor and overheat the machine if the belt is too tight. 

To adjust the belt, you’ll need a few tools:

  • Treadmill oil
  • A Phillips head screwdriver
  • An Allen wrench
  • A measuring tape

Start by applying a few drops of treadmill oil to the walking deck. Next, use a Phillips head screwdriver to loosen the front roller bolt. Then, use an Allen wrench to loosen the rear roller bolts. 

Now, you can use a measuring tape to determine how much you need to move the rollers in or out. If you need to move them in, tighten the rear bolts and loosen the front bolts. 

If you need to move them out, do the opposite. Once you’ve made adjustments, retighten all bolts before using the treadmill again.

more Tips To Make Your Treadmill Adjustment Process More Smoother

Like most people, you probably don’t give much thought to the treadmill adjustment process. But if you want to ensure your treadmill runs smoothly, it’s important to take a few minutes to properly adjust the machine.

Here are a few pro tips to help make the adjustment process go more smoothly:

1. Make sure the belt is tight enough. If the belt is too loose, it can cause the machine to vibrate and make a noise.

4. Make sure the console is at a comfortable height. If the console is too low, it may not be easy to see the display.
