Folasaga
I le tulaga o le faʻalavelaveina o soʻo se mea faigaluega vili i le taimi o le faʻalavelave faʻafefe, o le samala tua o le a fesoasoani ia te oe e faʻasaoina le taimi ma tupe.
O le samala pito i tua e mafai ona faʻapipiʻiina i luga o le paipa vili i le va o le puʻu puʻu ma le ulu taʻavale, ma faʻatupu ai se aʻafiaga tuʻufaʻatasia o aʻafiaga faʻafefe lelei ma le vibration.
Malosi ma fa'atuatuaina, o le samala pito i tua e aofia ai vaega e tolu ma se fale palasitika lea e fai uma e fai ma ta'iala fa'avevela ma se muftler.E tusa ai ma le tausiga, e na'o a'u e mana'omia e fa'amama ma puipuia lelei le vaega so'o pe a le ola le samala tua.
O le samala i tua ua mamanuina e tu'u ai le masini fa'apa'i lea e fa'asino i tua le malosi o le a'afiaga e fesoasoani e fa'asa'oloto le DTH Hammer ma paipa vili ua pipii i le pu vili.
Ua mamanuina le Samala i tua e fesoasoani e faasaoloto se samala DTH ma paipa vili ua pipii i le pu vili.E mafai fo'i ona fa'aoga e samala i lalo pe aveese fa'amau.
O le Samala i tua o lo'o fa'apipi'i i le va o le vaega ta'amilo ma paipa vili po'o le va o paipa vili.
DTH Samala ma paipa vili ua pipii ile pu vili.E faʻaaogaina lautele i le DTH ea vili.
