First I'll ask if you do the maintenance on your existing freehub, disassembling, cleaning and relubing? The F30 hubs have pretty much the same service interval, and service is pretty much just more of the same kind of thing.

From the Instruction Sheet: "No routine lubrication is required. During a major service, the hub greases should be replenished or replaced especially for transmission parts of internal hub."
