tootoo Polani

Fa'amatalaga Puupuu:

O le tootoo Polani o se ituaiga o la'au sucker fa'apitoa e feso'ota'i ma le tootoo sucker ma le tautau fa'amau. 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.
