As a treadmill is a mechanical machine whether you have a manual one or an electric one, it needs maintenance for its proper functioning. Thankfully, you do not have to do this maintenance on a regular basis. You have to simply make sure that the console and the belt of your treadmill are cleaned once a week. Apart from that, you have to oil the motor and gears of your treadmill every now and then. Fortunately, some treadmills come with a self-lubrication feature which makes this process automatic.
