In other words, knowing how to maintain a treadmill will come in handy in various ways, especially if you own one. In this guide, I’ll share every detail on how to maintain a treadmill. That way, you can keep it working effectively for longer!

How to Maintain a Treadmill: Step by step maintenance process

how to care for your treadmill

1. Wipe down the machine after every workout

Running or walking on a treadmill means that you’re going to sweat. This sweat will eventually drop on the machine. Similarly, any dirt from your running shoes will accumulate on the treadmill. As moisture and dirt start to accumulate, rust will eventually start to thrive on the belt and frame. Moreover, this will promote fungal as well as bacterial growth on the treadmill.

To avoid these challenges, make sure you wipe down your machine with a damp cloth after every workout. Using a soft brush, get rid of the dirt buildup on the treadmill belt. You can also use sanitizing wipes to remove sweat from the console, handlebars, and belt. Lastly, inspect and wipe the metal parts with a dry cloth.

2. Check for loose screws

Treadmills are held together by bold and screws. With heavy and repeated use, these screws and bolts will gradually loosen over time. For this reason, you should check and tighten any loose screws regularly.

On the same note, check and replace any corroded bolts and screws. If you don’t have replacement screws, buy them from the machine’s manufacturer. Otherwise, using the wrong bolts/ screw can damage your equipment.

3. Vacuum the space underneath

Dirt and dust tend to accumulate in the area underneath if you don’t clean it for too long. This build-up can add to the wear & tear of your machine. Moreover, it can interfere with your treadmill’s performance.

Therefore, it’s important to keep the floor area underneath your equipment clean. You can accomplish that is by vacuuming that area regularly. Use the vacuum cleaner’s hose attachment to remove as much dirt and dust as possible.

4. Clean the entire machine

Debris and dust will gather on your treadmill, regardless of whether you’re using it or not. You can use treadmill covers to keep dust away when storing the equipment. This dust will enter through small crevices and can even end up in the motor. As a result, this area will become clothed with dirt and dust. This will eventually cause damage to your workout machine. To prevent that, vacuum the entire machine at least once/ twice every month.

Cleaning the machine is an important part of the entire treadmill maintenance process. However, before you clean the machine, make sure the equipment is unplugged. Be careful when cleaning around the electrical parts to avoid any damage.

Moreover, read the manual before opening the motor compartment. This may provide extra details about cleaning the motor compartment. Next, carefully vacuum around the motor. As an alternative, you can wipe the area with a lint-free cloth. Close the compartment, plug in the machine, and turn it on for a minute after you’re done. Note, avoid using chemicals or liquids when cleaning the motor compartment.

Vacuuming should also be done around and in the treadmill belt and deck. Dust can accumulate around these areas, damaging or wearing down the belt.

5. Adjust the treadmill belt regularly

When functioning properly, the treadmill belt should be at the center of the deck. However, over time, the belt will start to slide off the treadmill’s center. As a result, the belt glides closer to 1 side of the deck when walking or running on the machine. Moreover, this may cause your machine to produce an unfamiliar sound.

· Why is my treadmill making a knocking noise?

Many factors can be causing your treadmill to produce a knocking noise. For instance, it may be resulting from a worn treadmill motor belt, loose roller pulley, or a fraying belt. However, the knocking sound may also be a result of a misaligned treadmill belt. This causes the belt to apply too much stress on the roller from one side to the other.

If you notice any of these issues, you need to align and tighten the belt. Belt alignment is not a difficult process. Most modern treadmills have 2 bolts on each side of the machine’s rear to help you with that. Simply turn the bolts anti-clockwise or clockwise until the belt is center-aligned. The movement will depend on the direction the belt is slipping from the treadmill’s center point.

If you’re unable to reset the belt, refer to the manufacturer’s manual. While adjusting the belt, make slight adjustments and monitor the progress.

Alignment balances the belt and reduces its chances of wearing down asymmetrically.

6. Maintain the belt tension

Most superior treadmills in the market have pre-adjusted belt tension. However, with repeated use, the treadmill belt tends to stretch out over time. As a result, the belt starts to loosen and slip off the deck. This can cause excessive wear & tear, both to the belt and deck. Once you notice the treadmill belt is slipping or loosening, you need to tighten its tension.

Modern treadmills come fitted with 2 tension bolts for tightening the belt. These bolts are usually located at the rear part of the machine. However, don’t make the belt too tight, as it can damage the rollers and motor.

Instead, use ¼ turn increments when tightening the tension bolts. After each adjustment, test out your treadmill at 3mph before you make proceed. This prevents over-tightening the belt by ensuring it has the ideal tension. Also, make sure you check the recommended belt tension on the manufacturer’s manual.

7. Regular treadmill lubrication

The treadmill belt is constantly moving when you’re walking or running on the machine. Also, the underside is consistently rubbing against components like rollers and motors. These movements generate friction, subjecting your equipment to premature wear & tear. Unwanted friction can also cause the treadmill to generate noise during use. To prevent these issues and ensure smooth movement, lubricate the moving parts regularly. Moreover, this will keep its components in excellent condition and extend their longevity.

Under normal circumstances, lubrication should be done after every 130 miles/ 3 months. But if you use your machine more intensely, inspect it more often to check if lubrication is needed.

Some modern treadmill models have self-lubricating features. But most models are still manual. What can you use to lubricate a treadmill? Most treadmill manufacturers recommend that you apply 100% silicone lube for the belt. Also, you should loosen the belt, apply the lubricant and re-tighten it once you’re done. Silicone is more durable and doesn’t harm your treadmill.

In general, there are 2 methods of lubricating the belt. The first method involves using a lubricant stick with a sponge pad and a handle. With this technique, you need to raise the belt on one end. Then stick the lubrication wand underneath the belt until it’s properly lubricated.

As an alternative, you can use a sponge or spray bottle to apply the treadmill oil underneath the belt. However, this technique may not be as reliable and effective as the first approach.

· How to perform treadmill lubrication?

To check if your treadmill requires lubrication, loosen the running belt. But before you get there, make sure the treadmill is unplugged. This is a necessary precaution when you’re performing any type of maintenance. Next, loosen the tension bolts with a screwdriver/ an Allen wrench.

After loosening the belt, place your hand underneath it and retract your hand. If your hand comes out with some oil, lubrication is not necessary. But if the hand comes out dry, that’s an indication that you need to lubricate it! To accomplish that, move on with the following steps:

  • Clean the treadmill deck with a lint-free cloth to remove dirt and dust under the treadmill belt.
  • Slightly lift the belt with your hand and slide the lubricant underneath.
  • Now, apply the treadmill oil, starting from the middle towards the belt edges. Then remove the lubricant bottle from beneath the treadmill belt.
  • Plug in the cable and power the machine back on.
  • Set the treadmill speed at a pace of about 3mph, and walk on it for about 4 minutes. This ensures that the lubricant is uniformly dispersed on the running belt.
  • Unplug the equipment again and slip your hand under the belt to determine if it’s well lubricated.
  • If your hand still feels dry, add more lubricant and test the machine again.
  • Once the deck is properly lubricated, tighten the tension bolts one side at a time.

8. Replace the running belt

Whether you’ve got a superior or a low-quality treadmill, the belt will certainly wear out over time. Oiling the machine regularly will make it last longer. However, at some point, belt replacement will be needed.

To determine if your belt requires replacement, look for signs of wear after every 3 months. If it appears worn and rough, it’s good to ensure that it’s replaced. Otherwise, the belt’s roughness will make the deck wear out more rapidly. As a result, you’ll be forced to replace both the belt and the deck.

9. Treadmill servicing

The maintenance tips we’ve looked at so far, are quick and simple DIY tasks. I’m talking about things like lubricating the belt and cleaning. However, at some point, maintenance will not help you anymore. For instance, if the treadmill is broken, maintenance will not fix the problem.

The same case applies to other parts like rollers, belts, motor, and console are damage. The ideal action to take is to contact a technician or professional. Hiring a professional for more detailed work will help you solve the issue with ease. Alternatively, contact the manufacturer, especially if your machine is still under warranty. Just don’t try to fix the problem yourself since it can cause more damage.

How to Set Up Your Treadmill
