When purchasing a treadmill, you really don’t think about the importance of proper maintenance. When you purchase a treadmill, you must be willing to take the time to maintain it just as you would any other major investment. Just like anything else, you must make a conscience effort to factor the maintence time into your schedule. Consider this prior to purchase. If you are proactive in the maintenance of your treadmill, you will add years to the life of your investment. Proper cleaning for the exterior of the treadmill is required, due to the fact that sweat is highly corrosive. This can be accomplished by merely wiping down the unit after each workout. Also, wiping down the belt and deck with a damp cloth will clean any debris that may effect the performance of the treadmill. That being said, the most important component of a treadmill is the belt. The belt is what drives the motor and your workout. A malfunctioning belt can cause many problems internally that can damage the motor, control board, belt or other major operating parts. There are really just a few rules to follow in maintaining and insuring the longest life of your walking belt. *The most important maintence item is adding supplemental lube when recommended (see your owners manual). Proper Lubrication will considerably extend the life of any treadmill walking belt. *Keep the treadmill clean, and evacuate any debris on or around the treadmill. *Do not place your treadmill in any extreme conditions. Treadmills should always be in a climate controlled room. *Keeping proper belt tension and tracking (belt should run parallel to the treadmill frame). This will maintain the belt in good working order. *Keep your treadmill on a level surface. Some treadmills have level adjustments on the rear supports. A treadmill will not track if not on a level surface.
