How to Tighten a Slipping Belt on a Treadmill

Before you begin working out on your treadmill, it is important to make sure it is in proper working condition. The main walking belt is a crucial part to the treadmill's overall function. When the main walking belt begins to slip, you must tighten it so you do not risk injury.

Things You'll Need

• Hex key (also known as an Allen wrench)

Instructions

1. Remove the treadmill power key and unplug the power cord from the power outlet.

2. Locate the rear roller bolts. They are directly to the outside of the walking belt, on the back of the treadmill. Use the hex key to turn these bolts clockwise, one-quarter of a turn.

3. Test the tightness of your belt. Grasping the belt in the middle of the walking platform, you should be able to lift each side of the belt 2 or 3 inches off the platform area.

4. Plug in the power cord, reinsert the power key, power it up and walk on the treadmill. Check for slippage.

5. If the belt is still slipping, repeat steps 1-4 until the walking belt has been tightened properly.

Tips & Warnings

• Be sure to turn each bolt the same amount; otherwise the belt can get out of alignment.

• Always unplug the power cord before attempting to tighten the belt.
