Sthil Harvester chain shapening question

[FastGame]

I bought a MS250 and it has Sthil LP 3/8 Harvester chain (don't know if that's good or bad) and I need to know if my sthil 3/8 sharpener kit is all I need, or do I need another type of file ? Any advice I need to know on sharpening this chain ?

Thanks.
