"This freewheel must be bedded in before trials use, to ensure any grease used when assembling the freewheel works away from the mechanism. If the freewheel is subjected to trials use without having been bedded in, the pawls will not engage correctly and this causes the freewheel to skip, damaging the pawls and ratchet. If you wish to speed up this process, you can thin the grease down with light oil like GT85 or WD40. Failure to bed the freewheel in correctly will void the warranty."
