      Fa'aaliga 1.5: Afai ei ai ni faaletonu, o loʻo faʻamatalaina i lalo, i totonu o le itulagi autu ma / poʻo le pito i fafo, o le vaega e ufiufi ai le 3 mm mai itu taʻitasi o le faaletonu e tatau ona faʻamatalaina o le vaega e le mafai ona faʻaaogaina (Ata 1.3). I lenei tulaga, o le umi aoga e tatau ona faʻamalamalamaina e le aofia ai le umi o le vaega e le faʻaaogaina. O le vaega e le mafai ona faʻaaogaina o le a faʻaalia e le "Defect MAP", lea e tatau ona faʻapipiʻi i le pepa suʻesuʻe.
      Fa'aletonu:
