Life Fitness Treadmill. The most important maintenance task on a treadmill machine is periodically lubricating the treadmill belt. As you use the machine, oil on the rollers and ball-bearings tends to dry out, and if you don't keep the belt properly oiled, you might end up having to buy a new belt, which can be costly. Lubrication won't make a belt last forever, but it will extend its lifespan significantly.
- Unplug the treadmill from the wall.
- Remove the flywheel cover from the treadmill, using a wrench.
- Loosen the pulley tension on the treadmill belt by loosening the side screws on the belt platform. Do this with a screwdriver.
- Consult your treadmill's user manual to determine where to put the lubrication. Most models will have you apply it one of two places: either between the underside of the belt and the platform, or directly onto the ball bearings and rollers. Apply the lubrication.
- Tighten the side screws, replace the flywheel cover and plug the treadmill into the wall.
- Run the treadmill for a couple of minutes on the lowest speed setting to let the oil disperse. Do not use the treadmill during this time.
