How to Lubricate a Treadmill

A treadmill helps users achieve their fitness goals and lose some pounds in the comfort of their homes. However, like other equipment with moving parts, it experiences wear and tear in its running belt and deck surfaces over time. If you notice that your treadmill is producing more noise than when it was new, this can be a clear sign that it’s in desperate need of lubricant.

Lubricating your treadmill can prolong its life and assist in operating the treadmill belt at top performance. Failure to keep your treadmill lubricated can cost you a fortune. A poorly-lubricated treadmill can increase energy usage, control board and motor burnouts, and treadmill belt delamination or degradation.

But how do you lubricate a treadmill? Well, if you’re new to this concept, here’s how to lubricate a treadmill.

Why do treadmills require lubrication?

Here is why you should make lubricating your treadmill a regular home gym maintenance practice.

  • Lubricating a treadmill will help you prepare the machine for storage.
  • Treadmill lubricant prolongs the life of the track by minimizing friction between the motor and the tread belt.
  • Without proper lubrication, the belt may grow stiff and break when the treadmill is started.

Maintaining a treadmill belt is less expensive than replacing one.

What to use in lubricating a treadmill

Most treadmill brands claim that the 100% silicone oil treadmill belt is the best product for treadmill lubrication. However, there are other alternatives like powdered wax, treadmill wax sticks, and paraffin-based lubricants.

However, you should not use grease or oil manufactured for other purposes because they can clog the treadmill or damage it. You should also buy a treadmill mat to keep the belt area clean and free from debris.

How often should you lubricate a treadmill?

Lubricating your treadmill regularly can guarantee you the most comfortable workouts possible. Essentially, you should avoid premature wear and tear on the motor and the running deck. Most manufacturers recommend that you should lubricate your treadmill after every 130 miles or every three months, in normal use. You should not wait for unusual sounds that signal excessive friction. However, always stick to the manufacturer’s recommendations in their instruction manuals.

How to lubricate a treadmill (steps)

Disconnect the Treadmill from the Power Outlet

Before applying the lubricant to the machine, disconnect it from the wall outlet. This is important for your safety since it prevents the machine from running while working on it.

Lay Down the Towels

The excess lubricant will drip from your treadmill regardless of how keen you are. Therefore, it’s advisable to place towels along the edge of your machine. This will prevent permanent grease stains on your floor. However, ensure you have enough towels to wipe off extra grease from the treadmill after you’re done.

Disconnect the Treadmill Deck

After placing the towels, you need to dismantle the lower part of the running belt. All you need is to loosen the rollers and lift the edges of the running belt. Alternatively, use a screwdriver of the right size and type.

Apply Lubricant to the Treadmill Deck

As stated previously, this is a very simple process, especially if you’re using silicone spray for treadmills. Make sure you spray the lubricant evenly on the deck. If the lubricant is too thick, wipe off the excess oil to prevent it from becoming too slippery.

Move the Running Belt

After lubricating the running deck, apply a thin grease layer to the entire belt. This will ensure that the underside of the treadmill is well lubricated. Move the running belt while applying the lubricant to ensure that the entire belt is well-covered.

Wipe Out Excess Treadmill Lubricant

Wipe out any excess lubricant on your machine. Also, ensure that you wipe off any grease on the top or side of the running belt.

Tighten the Running Belt

Place the running belt to its initial location and tighten the screws. When the belt is tightened properly, the deck should not lift off the deck by more than one to two inches.

Test the Machine

To check whether the treadmill is well lubricated, connect it to the wall outlet and turn it on. Run it for about 3 minutes at a low speed to distribute the lubricant evenly. Lastly, walk on the treadmill to test how it’s working.


Can you use WD 40 to lubricate a treadmill?

No. WD-40 is a petroleum-based lubricant that can damage your treadmill. Always use the oils indicated by the manufacturer or a silicone-based lubricant if not indicated in the manual.

How do I know if my treadmill needs lubricant?

Touch the deck under the tread belt to check if your treadmill needs lubrication. If you don’t feel a waxy coat or slightly oily lubricant on the deck, you need to lubricate it.

How much oil should I use to lubricate my treadmill?

Lubricating your machine after three months can consume about 1 to 1.5 oz of lubricant per application.

Like other workout equipment, treadmills require regular maintenance to ensure a smooth operation. Knowing how to lubricate your treadmill is part of the maintenance routine. Ensure you follow the manufacturer’s instructions and use the right lubricant.
