Tohutohu
Ka taea e te Needle Valve te mahi a-ringa, aunoa ranei.Ka whakamahia e nga riu ngira a-ringa te wira-a-ringa hei whakahaere i te tawhiti i waenga i te pupuhi me te nohoanga takirere.Ka huri te wīra ringa ki te taha kotahi, ka hikina te plunger ki te whakatuwhera i te takirere kia puta te wai.Ka huri te wira-a-ringa ki tetahi atu huarahi, ka neke tata atu te piu ki te nohoanga ki te whakaheke i te tere rere, ki te kati ranei i te takirere.
Ka honoa nga riu ngira aunoa ki te motuka waipēhi, ki te kaitahuri hau ranei e tuwhera aunoa ana, e kati ana i te takirere.Ka whakatikahia e te motini, te kaitahuri ranei te tuunga o te pupuhi i runga i nga taima me nga raraunga mahi o waho ka kohia i te wa e tirotirohia ana nga miihini.
Ko nga riipene Needle e rua e whakahaeretia ana e te ringa me te miihini aunoa e whakarato ana i te mana tika o te rerenga rere.He miro pai te wira ringaringa, ko te tikanga he maha nga huringa ki te whakatika i te tuunga o te piu.Ko te mutunga mai, ka taea e te niira te awhina i a koe ki te whakarite pai ake i te rere o te wai i roto i te punaha.
