Takirere Kēti Whakahaere Āhuarangi
✧ Whakaahuatanga
Ka peia te takirere kuaha whakahaere hau e te whakaoho hau o te hau kōpeke, ina kati te takirere kuaha, ka taea anake te whakawhirinaki ki te pehanga mahi rauemi hei hiri, arā, ka pēhia te mata o te takirere kuaha e te pehanga mahi pāpāho ki tera taha o te nohoanga takirere kia mau ai te hiri o te mata, ka hiri-ā-ia anō. Ko te nuinga o ngā takirere kuaha ka akiakihia kia kati, kātahi ka kati te takirere kuaha, ka whakamahia te kaha ki te pēhi i te takirere kuaha i runga i te nohoanga kia mau ai te hiri o te mata.

✧ Ngā Āhuatanga o te Takirere Kēti Whakahaere Āwhina Hau
1. Ko te takirere kuaha hau he mea hanga mai i te pereti hinu, te takirere rere kotahi, te takirere kuaha, te nohoanga, te mowhiti hiri, te rango takirua me te tokotoko piston, te rango waipēhi, te diaphragm me tana tikanga parepare, te whakaritenga ā-ringa, ngā taputapu whakawhiti ringaringa hau me te hanganga hiri takirere rere kotahi.
2. Ina tae te tokotoko piston ki te tihi o te whakaritenga haere, ka taea e ia te whakatairanga i te kaiwhiwhi tohu mōhiohio ki te tuku mōhiohio; I raro i te whakaritenga haere whakararo o te tokotoko piston, ka tukuna ngā mōhiohio mai i te kaiwhiwhi tohu mōhiohio taraiwa-iho, e whakaatuhia ana hei mōhiohio whakatuwhera/kati o te takirere kuaha i runga i te papatohu whakaata i roto i te rūma pokanga.
3. Kei te piki, kei te heke rānei te kuaha wai o te tokotoko tohu iri i te taha o runga o te wira ringaringa. Ina kati te takirere kuaha, kei raro te taputapu whakaatu matihiko waewae tautoko; ā, ina tuwhera katoa te takirere kuaha, kei teitei te taputapu whakaatu matihiko waewae tautoko. Koinei hoki te tohu wāhi o te tuwhera me te kati o te takirere kuaha.
4. Kei te wāhanga o runga o te pane rango he taputapu huri ā-ringa-hau. Hurihia te tokotoko mamao huri ki te taha matau ki te kōhao tūnga hau, ā, ka noho te takirere kuaha ki te āhua mahi hau; i te tahuritanga, hurihia te tokotoko mamao ki te taha maui ki te taha ā-ringa, ka taea e koe te whakamahi i te takirere kuaha hei whakahaere i te mahi ā-ringa. Ka huri te tokotoko mamao me te taputapu porowhita porowhita ki te taha ke. Ina whakahaerehia ā-ringa te takirere kuaha, ko te ahunga o te nekehanga o te wira ringaringa he rite ki te ahunga o te takirere ā-ringa whānui, arā, ka huri te ahunga o te porowhita ki te whakaweto, ā, ka huri te ahunga whakamuri ki te whakakā. Ka huri te taputapu porowhita porowhita ki te taha ke.
✧ Ngā Painga o te Takirere Kēti 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.
