Takirere Pūrerehua Tauhou Takitoru
Tetakirere pūrerehua rerekē toru— e mōhiotia ana ko te takirere pūrerehua takitoru-whakarerekētanga — he takirere pūrerehua mahi-teitei i hangaia mō ngā tono pēhanga teitei, pāmahana teitei, me te huringa auau teitei. Ahakoa he pono, he whai hua hoki ngā takirere pūrerehua kua whakakikoruatia ki te rapa porowhita mō te ratonga whānui, kāore i te pai mō ngā āhuatanga kino pēnei i te pāmahana teitei, i ngā auau mahi tino teitei rānei. Ka aro atu ngā takirere pūrerehua mārō-nohoanga tikanga ki ētahi o ēnei herenga, engari ko tā rātou mahi hiri i raro i ngā āhuatanga uaua he āwangawanga i mua. I whakawhanakehia te takirere pūrerehua takitoru-whakarerekētanga hei wikitoria i ēnei herenga.
He mea nui te nohoanga ki te tinana o te takirere, me ngā koki nohoanga kua whakapaitia me ngā paninga ārai-kakahu e tika ana mō ngā miriona huringa mahi. Ka whakaratohia e te hanganga maitai kore waikura te ātete ki te waikura, ā, kei te wātea ngā rauemi pāmahana teitei mō ngā taiao wera nui. Ka whakapirihia ngā mowhiti hiri ngohengohe maha-paparanga, ngā mowhiti hiri whakarewa mārō rānei ki te kōpae, ka nui ake te ātete o te takirere ki te ru wera, ki ngā tihi pēhanga, me te waikura ki te whakataurite ki ngā takirere pūrerehua tikanga.
Ka tutuki te kore turuturu mā te mowhiti hiri maitai kore waikura e mau ana ki te kōpae. Mā te āhua motuhake o te toru-āhua rerekē ka taea te huri i te koki matau me te kore waku - ka whakakore i ngā pa katoa i waenga i te nohoanga me te mowhiti hiri puta noa i te whiu 90°. Ka tino whakaitihia te taipana mahi, ka taea ai te tohu i tētahi kaiwhakaoho iti ake, he iti ake te utu.
Ina kati, ka whakanuia e te pūnaha tuku te taipana kia pai ai te hiri. I te wā kotahi, ka whakarei ake tēnei pūnaha i te mahi hiri, ā, ka roa ake te roa o te ora o te takirere.
- 1Kei muri i te pokapū o te kōpae te rakau takirere, e āhei ai te mowhiti hiri ki te kati katoa ki te nohoanga takirere me te kore e pokanoa.
- 2Kua wehea te rārangi pokapū o te rakau takirere mai i te rārangi pokapū paipa me te rārangi pokapū takirere, ā, ka kore e pokanoa i te wā e tuwhera ana, e kati ana hoki.
- 3Ka peka ke te tuaka o te koeko nohoanga mai i te rārangi pokapū o te kakau takirere, ka whakakorea te waku puta noa i te whiu katoa, ā, ka tutuki ai te hiri pēhanga ōrite huri noa i te porowhita nohoanga katoa.
