Just like any machine, the elliptical cross trainer also requires regular maintenance. For proper functioning and long life of the equipment, one should clean, lubricate, check nuts and bolts, check the levelling and stabilizing and inspect the drive belt. Cleaning should be done at least monthly, and servicing twice a year. It would be best if you kept the machine dirt, dust and sweat free to avoid problems in smooth functioning. Extra care should be taken with the elliptical cardio machine, especially if it is kept in places prone to more dust, like a basement or garage.
