saint M800 hub bearings renewal

does anyone know of any diagrams or instructions on replacing/serviving hub bearings front and rear for saint M800 hubs? Mine could do with a good service but not having done one of these before would like to have an insight before doing it.
also, any ideas which bearings i would need to get if i had to replace them? can you put sealed bearings in?
cheers
