Fa'amatalaga o oloa
1.Polish rod o se ituaiga o sucker faʻapitoa e fesoʻotaʻi ma sucker rod ma faʻamau tautau.O loʻo i le pito i luga ole laʻau sucker, e manaʻomia ona sili atu le malosi, o lea e sili atu le lautele ma maualuga le maualuga o le sila nai lo le sucker rod, ma o le luga e matua lamolemole.
2.Main galuega tauave:
Faʻatasi ma le faʻapipiʻiina o seti i totonu o pusa pusa e faʻamaufaʻailoga ai le ulu lelei ma puipuia le faʻaalia o le suauu, kasa, vai.
Feso'ota'i le tumau i le va o le la'au sucker ma le tautau ulu o miula
Fa'ai'u su'ega ata fa'ailoga.
Fa'ato'a fa'agaoioiga eseese ole ulu lelei, e pei ole ta o le pamu, fa'atonu le fa'atulagaina o pamu.
