How to Maintain a Treadmill: 3 Easy Steps to Keep It Running Smoothly

A treadmill is one of the most popular pieces of home fitness equipment. It helps you lose weight, boost metabolism, and strengthen your heart and lungs. However, just like any other machine, your treadmill also needs regular maintenance to perform at its best and last longer.

Fortunately, maintaining a treadmill is easier than you might think. Follow these three simple steps, and your treadmill will stay in top condition for years.

1.Regular Cleaning – Keep Dust Away and Components Healthy

Over time, dust, sweat, and debris can accumulate around and under the treadmill belt. If not cleaned regularly, these particles can cause friction, noise, and damage to the running deck.

Here’s how to clean your treadmill properly:

Wipe the running belt and handrails after every workout using a soft, damp cloth.

Clean the area around and beneath the belt every week to prevent dust buildup.

Make sure your shoes are clean before use to avoid carrying dirt onto the belt.

Avoid using alcohol or harsh cleaning agents — mild soap and water work best.

Perform light cleaning after each use and deep cleaning every two weeks for optimal performance.

2.Apply Lubricant Regularly – Reduce Friction and Protect the Motor

Lubrication is essential for the treadmill’s longevity. Without proper lubrication, friction between the running belt and deck increases, leading to belt deformation and potential motor damage.

How to lubricate a treadmill:

Turn off and unplug the treadmill.

Gently lift the belt and apply treadmill-specific silicone oil evenly between the belt and deck.

Restart the treadmill and let it run at a slow speed (about 3 km/h) for 5 minutes to distribute the oil.

Wipe off any excess lubricant.

As a general rule, lubricate your treadmill every 40 hours of use or every two months. If you run frequently, consider doing it more often.

3.Adjust the Running Belt – Keep It Centered for Smooth Operation

A misaligned belt is a common issue that can cause friction, slipping, or uneven running surfaces. Regularly checking and adjusting the belt alignment will keep your treadmill running smoothly.

How to realign the treadmill belt:

Set the treadmill speed to 3–6 km/h.

If the belt moves to the right, turn the right adjustment bolt clockwise ½ turn and the left bolt counterclockwise ½ turn.

If the belt moves to the left, do the opposite.

Let the treadmill run for a minute to check alignment, then fine-tune if necessary.

Make small adjustments each time — about ⅓ to ½ turn per bolt — to avoid overcorrection.

Final Thoughts

Taking care of your treadmill is not complicated — it just requires a bit of consistency. By following these three key maintenance steps: cleaning, lubrication, and belt adjustment, you can extend the life of your machine, enhance workout comfort, and prevent costly repairs in the future.

A well-maintained treadmill doesn’t just last longer — it makes every run smoother, safer, and more enjoyable.
