6. Teuina & Tausiga & Fa'apipi'i & Fa'agaioiga
6.1 E tatau ona teuina le valve i totonu o le potu mago ma lelei le ea .o pito o le ala e tatau ona faʻapipiʻi i ufiufi.
6.2 Valve i lalo o taimi umi teuina e tatau ona suʻesuʻeina ma faʻamamāina e le aunoa, aemaise lava nofoa faʻasaga e puipuia ai le faʻaleagaina, ma o le nofoa nofoa e tatau ona ufiufi i le suauʻu e taofia ai le ele.
6.3 E tatau ona siaki le makaina o alavai ina ia tausisia le fa'aoga.
6.4 E tatau ona siaki le avanoa o le valve ma le faʻamaufaʻailoga aʻo leʻi faʻapipiʻi ma aveese le palapala pe a iai.
6.5Arrow itu e tatau ona tutusa ma le itu tafe.
6.6 E tatau ona fa'apipi'i sa'o i luga o le paipa le si'i i luga o le va'a siaki tisiketi.E tatau ona fa'apipi'i fa'alava i le paipa le si'iina o le va'a siaki fa'alava.
6.7 E tatau ona siaki le vibration ma e tatau ona maitauina le suiga o le mamafa o paipa e puipuia ai le aʻafiaga o le vai.
7. Faʻafitauli e ono tupu, mafuaʻaga ma fua faʻaleleia
