Uamea Nifo Tricone Bits
1, Fa'atonuga vaivai(114-117)
O fasi mea nei ua mamanuina e viliina ai mea e sili ona vaivai e pei o shales malu, moega mumu, ma omea, e maualuga le umi ma le maualuga o le ulu.
2, Fa'atonuga vaivai ma feololo(121,124,126,134,136,137)
O fasi mea nei ua mamanuina e vili ai fausaga e pei o ma'a, ma'a ma'ale'ale feololo, ma'a oneone Medium ma isi mea fa'apipi'i fa'asolosolo malo.
3, Faiga e feololo i le malo(213,214,215,217)
O fasi mea nei ua mamanuina e viliina ai fausaga e pei o le maa oneone malo, dolomite, ma le malepelepe o lo'o i ai ni ma'a malō.
