The ProForm 585 treadmill is built for home use and includes several features, such as the Weight-Loss Center and built-in Personal Trainer Workouts that offer you a variety of settings for your treadmill workouts. This model also has a music port for your iPod and a heart-rate monitor. The cushioned belt is supported by a self-cooling drive system for smooth operation but the belt can wear out with use. If your belt feels or looks worn or torn, you can have it replaced if it is still under warranty or you can replace it yourself.

    Apply half a tube of lubricant between the top part of the deck and belt and the other half of the tube between the underside of the deck and belt. Apply the lubricant lengthwise along the deck.

    Plug the treadmill back into the wall socket and turn it on. Let it run at two to three miles per hour for five minutes to allow the lubricant to be distributed evenly along the deck and belt. Do not stand on the treadmill during this time.
