Oil Maintenance Of The Inner Set Unit - Shimano Nexus Inter-8 Dealer's Manual

„ Oil maintenance of the inner set unit
• In order to maintain proper performance of the product, it is
recommended that you ask the place where you purchased
the bicycle or your nearest Pro shop to carry out
maintenance such as greasing the internal parts about once
every two years from the first time of use (once about every
5,000 km if the bicycle is used very frequently). It is also
recommended that you use the Shimano internal hub grease
or lubrication kit when carrying out maintenance. If the
special grease or lubrication kit is not used, problems such as
gear shifting malfunction may occur.
