What Kind of Maintenance Does a Treadmill Need?

As handy as it is, a treadmill wouldn’t last for a long period of time if you don’t take care of it. There are a number of things you need to address while maintaining your treadmill. Some important points to remember include:

Wipe Down the Treadmill after Each Use

Whether you are sprinting at high speeds or casually jogging on a treadmill at a slow speed, the treadmill tends to get dirty due to the sweat dropping on it and the dirt from the shoes. You need to wipe down the sweat from all places and really get in there with a wet cloth. Make sure that you remove all traces of sweat because in case you left some spots, they can be quite difficult to remove afterward. Also, the dirt on the belt needs to be removed with the help of a soft brush.

Treadmill Maintenance Lubrication

Clean Around and Under the Treadmill

As much as cleaning the treadmill is important, making sure that the areas around the unit are also kept clean is an essential part of the whole maintenance process. Moreover, the dirt around the treadmill can deteriorate the operation of the treadmill. Make sure that the treadmill is unplugged, and be careful around the electrical components to avoid any unfortunate incident.

Vacuum Out the Treadmill

Whether the treadmill is being used or not, dust and debris can gather on the machine and under the treadmill’s motor housing over a period of time. You should vacuum the treadmill, not only from the outside but also around and under the motor cover area beneath the belt (such as the drive belt and the pulleys), to make sure it is clean and runs smoothly without any nuisance. This should be done at least once a year, depending upon the frequency of usage.

Treadmill Maintenance Lubrication

Lubricating your treadmill from time to time is an important part of the maintenance process. To lubricate the unit, you need to follow the instructions given in the owner’s manual that comes with the treadmill. You’ll be required to loosen the belt when you lubricate your treadmill and then tighten it back once you’re done. Be careful not to spray the top and make the belt slippery, and wipe off any excess lubricant with a soft cloth.

An important thing to check is that some treadmills don’t require any lubrication as their components come with a special wax, and lubricating them can damage the machine or cause excessive wear. So make sure you keep an eye out for that.

Installing A Treadmill Mat Under the Machine

Placing a treadmill mat under the machine will minimize any kind of noise and vibrations it causes while you use it, especially if you want to use the treadmill on the second story of your house. Moreover, using treadmill mats under the machine will prevent any kind of debris, like pet hair and dirt from shoes to gather under it and help you vacuum easily when required.

Tightening a Treadmill Belt

With the passage of time and excessive usage, even the best treadmills require belt alignment. The belt can get loose and start slipping, causing damage to the treadmill deck and the belt itself. To tighten the belt, you need to tighten up the bolts with an Allen wrench or screwdriver to bring it back to the ideal belt tension. Also, to avoid tightening it too much, always consult the owner’s manual before the procedure.

Adjusting and Aligning the Treadmill Belt

To attain optimal functioning of a treadmill, you need to ensure that the belt is rightly aligned. You need to check whether the belt runs straight down the deck’s center. If it doesn’t follow the path, alignment is required. Bolts on each side of the rear end of the machine need to be adjusted to gain optimal alignment. Slightly make adjustments and keep checking until the required alignment is achieved.

FAQs About Treadmill Maintenance

Now, let’s take a look at answers to some of the top FAQs regarding treadmill maintenance so that you have a better understanding of the different aspects involved.

How to Glue Treadmill Belt?

Put off replacing the belt until you really have to, but if the rip is that big, the walking belt should be replaced. You may also contact the manufacturer, if the treadmill is still under warranty they may provide a new belt.

If the treadmill belt is too loose, don’t risk the taping technique. A flexible glue or silicone glue may also help the belt for awhile, however, don’t risk your health for a cheap solution, have the belt replaced.

How to Repair Torn Treadmill Belt?

If a walking belt is torn and opened up, the belt’s integrity is compromised. It is safer to completely replace the belt and avoid an unwanted injury at a random time. A treadmill is usually torn when the belt is too tight or there is too much friction. Leave 2-3 inches of a gap to avoid an overtightened belt.

How Often Should a Treadmill Be Serviced?

The frequency of service for any treadmill depends on various factors related to the amount and nature of usage.

We recommend that you get your treadmill checked by a professional for optimal functioning.

Can You Use WD 40 to Lubricate a Treadmill?

No, we advise against using WD-40 or any other household lubricant for your treadmill. You should only use specially designed silicone lubricant for treadmills, as household lubricants can cause damage to your machine and negatively affect its performance.

Should I Turn Off the Treadmill when I Don’t Use It?

Definitely; you should always turn off the treadmill when not in use. This is because the treadmill can be damaged due to power surges, and the fluctuation in voltage can actually cause damage to the cords. Many people suggest using a surge protector, but the versatile power demand by a treadmill for its different speeds and modes does not make it suitable for use.
