Takirere Mono Mana Whakahohe Hau
✧ Whakaahuatanga
Me whakamahi noa te pūkaha hau i te pūkaha hau hei huri i te 90 nekehanga me te pūtake hau, ā, ka taea te kati pūmau i te taipana hurihuri. He ōrite te rūma o te tinana o te pūkaha, e whakarato ana i te ara rere tika me te kore e ātete ki te reo. I te nuinga o te wā, ko te pūkaha mono te mea tino pai mō te whakatuwhera me te kati tika. Ko te āhuatanga matua o te pūkaha pōro he hanganga kiato, he ngāwari te whakahaere me te tiaki, he pai mō te wai, ngā whakarewa, ngā waikawa me te hau māori me ētahi atu rauemi mahi noa, engari he pai hoki mō te hāora, te hauwai waikura, te methane me te ethylene me ētahi atu āhuatanga mahi kino o te pāpāho. Ka taea te whakauru, te whakakotahi rānei i te tinana pūkaha o te pūkaha mono.
Ka mahi te takirere mono hau mā te huri i te pōro hei whakatuwhera, hei kati rānei i te takirere. He māmā te pana o te takirere mono hau, he iti te rahi, he nui te diameter, he pono te hiri, he māmā te hanganga, he ngāwari te tiaki. Ka kati tonu te mata hiri me te mata mono, ā, kāore e ngāwari te pirau i te reo. Kua whānuitia te whakamahinga i roto i ngā ahumahi rerekē. He rite tonu te momo takirere o te takirere pōro hau me te takirere mono, engari he porowhita tōna wāhanga kati, ka huri te porowhita i te rārangi pokapū o te tinana takirere hei whakatutuki i te whakatuwheratanga me te katinga.

✧ Ngā Āhuatanga o te Takirere Mono Whakahaere Āwhina Hau
1. He iti te ātete wai, ā, he ōrite tōna tauwehenga ātete ki te wāhanga paipa o te roa ōrite.
2. Hanganga māmā, rahi iti, taumaha māmā.
3. Pūmau, pono hoki. He whānuitia te whakamahinga o te mata hiri o te takirere mono ki te polytetrafluoroethylene me te konganuku, he pai te mahi hiri, ā, kua whānuitia te whakamahinga ki te pūnaha korehau.
4. He ngāwari te whakahaere, he tere te whakatuwheratanga me te katinga, he 90° noa te hurihanga mai i te whakatuwheratanga katoa ki te katinga katoa, he mana mamao watea.
5. He ngāwari te tiaki, he māmā te hanganga o te takirere pōro hau, ka taea te tango i te mowhiti hiri whānui, he watea te wetewete me te whakakapi.
6. Ina tuwhera katoatia, ina kati katoatia rānei te takirere, ka wehea te mata hiri o te mono me te nohoanga mai i te reo, ā, e kore te reo e pakaru te mata hiri o te takirere.
✧ Ngā Painga o te Takirere Mono Whakahaere Āwhina Hau
I te wā e whakatuwheratia ana, e kati ana hoki te takirere porowhita maitai hanga, nā te mea he iti ake te waku i waenga i te kōpae me te mata hiri o te tinana takirere i tērā o te takirere kuaha, ka ātete ki te kakahu.
He poto noa te whiu whakatuwheratanga, te whiu kati rānei o te kakau takirere, ā, he tino pono te mahi tapahi, ā, nā te mea he rite te huringa o te putanga nohoanga takirere ki te whiu o te kōpae takirere, he tino pai mō te whakatikatika i te tere rere. Nō reira, he tino pai tēnei momo takirere mō te tapahi, te whakahaere rānei me te whakawhāiti.
