The ECO Plus 3 hub system is designed for the use of longlife grease. On expiry of the guarantee, the roller bearings, the inside
of the hub and the seals are to be thoroughly cleaned (with diesel oil), dried, checked to see if they can be re-used; and re-greased
every three years when used off-road, or every 5 years when used on the road, within Europe (or every year when off-road and every
two years when on the road outside of Europe) (observe the current BPW maintenance instructions).
Apply BPW ECO-Assembly and Protection Spray as thin as possible and around the entire area of bearing seats of the axle stub.
