"This freewheel must be bedded in before trials use, to ensure any excess grease used when assembling the freewheel works away from the mechanism. You can do this by riding the freewheel around 'normally' for a few hours, both freewheeling and engaging the mechanism gently. 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, by spraying it between the centre and outer teeth of the freewheel and rotating it."
