Spirit Manufacturing created Spirit Belt Lubrication Kits because the company does not advise its customers to lubricate their equipment belts with any other lubrication. If the equipment is kept reasonably clean it is possible to expect more than 1,000 hours before additional lubing is necessary. The manufacturer produces treadmills and elliptical machines. Spirit Manufacturing s Z Series line of treadmills includes the 1.5-horsepowered Z8, 3.0-horsepowered Z9 and the cooling-fan inclusive 3.0-horsepowered Z100, Z300, Z500 and Z700. Treadmills produced under the company s Inspire line include the 1.25-horsepowered in839, 2.0-horsepowered in200 and the 3.0-horsepowered in400. Its elliptical machines are sold under the ZE line. The models include the ZE20 and the ZE50. The company is headquartered in Jonesboro, Ark.
