How often does the Fine Cyclo® require maintenance?
Customers should never open the Fine Cyclo. The reduction stages of the FA-Series reducers are lubricated for life. Additionally, their internal components are matched in such a way that makes re-assembly very difficult for untrained personnel. If desired, customers may return Fine Cyclos to Sumitomo for grease replenishment after 5 years in order to increase service life.
