This article will review how to lubricate a treadmill so you can keep your machine running smoothly—pun intended.

Signs Your Treadmill Needs Lubricant

There are a few ways to know if your treadmill needs lubricant. The simplest way? Stick your hand under the belt. It’s good practice to check under the treadmill’s belt every now and then. (Be sure the machine is off and unplugged before you do!) It should feel oily or waxy, and if it doesn’t, it’s time for some lubricant.

However, there can also be other signs that your treadmill needs lubricant. If you’re one to listen to your jams while on a run or walk, take an earbud out every now and then to listen to the treadmill at work. If you notice any squeaking or loud noises, your treadmill may need a refresh on lubrication.The belt may also need lube if it feels slippery or sticky when in motion. A slippery belt can be a common issue for treadmills, but thankfully it can be an easy fix.

If your treadmill is new, check under the belt before applying lube as many new treadmills come pre-lubricated. If you’re unsure, check the user manual or call the company to confirm.

How Often Should You Lubricate a Treadmill?

Once you figure out how to lubricate a treadmill deck, you might wonder how often your treadmill actually needs it. The frequency may vary between treadmill manufacturers, but the general consensus is that the average treadmill user should lubricate the running belt once every three months or after approximately 40 hours of use. That is unless you’re logging more miles than the average person. If you’re putting down some intense workouts on your treadmill, you may need to lubricate the belt more frequently.

It’s also important to note that treadmills in warmer climates may need lubrication applied more frequently. The warmer the climate, the faster the lube can dry out.

Check the owner’s manual for specific recommendations for your treadmill and be sure to regularly check your machine’s parts.

Tools Needed To Lubricate Your Treadmill

You really don’t need anything fancy to lubricate your treadmill. The most important thing you’ll need is the correct treadmill belt lubricant for the job. You may also need an Allen wrench or a screwdriver to loosen the treadmill belt.

Most treadmill lubricants are 100% silicone oil, or silicone-based. You should not use petroleum products like WD-40 as they can ruin your treadmill. Your machine’s user manual will specify the type of lubricant your treadmill requires. Some companies even sell specific lubes for their machines.

How to Lubricate a Treadmill: Step-by-Step Guide

Lubricating a treadmill can look different between brands. For example, how to lubricate a NordicTrack treadmill may not be the same as how to lubricate a Horizon Fitness treadmill. However, in general, you can expect to:

Start by shutting off your treadmill and unplugging the machine (for safety reasons).
Using your hand, reach under the belt to feel for lubrication and dirt. You may need to loosen your treadmill’s belt to be able to fit your hand underneath.
Using a cloth, wipe underneath the treadmill belt to ensure it’s clean before applying the lubrication.
Starting on one side of the treadmill (approximately one foot from the hood and a few inches from the edge), disperse the lubricant under the belt in a zig-zag pattern moving toward the end of the deck surface.
Repeat on the other side of the belt.
Now that the lube is in place, retighten the belt and plug the machine back in.
Turn the treadmill on and let it run for about five mins at around 3 miles per hour, so the lubricant has a chance to spread evenly.

And voila! You’ve successfully applied lube to the running deck. It’s relatively simple, and it helps keep your treadmill running strong. Oops, another pun! That’s the last one, I promise.
