In order to adjust the belt on a treadmill, you will need to find the screws that hold it in place. These screws are typically Hex screws, which means they will require an Allen wrench or hex key to remove. Once the screws are removed, you can then adjust the belt according to your needs.

If the belt on your treadmill becomes worn or frayed, it will need to be replaced. 

Do not over-tighten the screws; they should only be tightened a quarter turn at a time.

And make sure the belt is in the centre of both boards and tightened evenly. This will ensure that your treadmill runs smoothly without any wobbling.

Also, make sure you have the correct size belt for your treadmill if you are installing a new treadmill belt.

You can find this information in the owner’s manual or by contacting the manufacturer.
