E whā ngā huinga pungarehu paparua o te maitai waro DN150ngā takirere tukungaKua oti pai te whakamātautau mahi katoa o te wheketere, ā, kua rite mō te tuku ki ngā kiritaki. He mea hanga mai i te maitai waro Q235B, he mea hanga ēnei takirere mō ngā āhuatanga mahi e uru ana ki ngā matūriki totoka tae atu ki te puehu me te pungarehu oumu. Kua paahitia e ia waeine he whakamātautau pakari mō te hau me ngā whakamātautau huringa whakatuwhera-kati anō, ā, kāore he turuturu. I tukuna ngā ataata whakamātautau katoa ki ngā kiritaki puta noa i te tukanga tirotiro, ā, i tino mōhiotia te mahi hiri hau-rakau pai rawa atu.

E kiia ana hoki ko te takirere tuku pungarehu papa rua, ko te takirere raka hau papa rua, he taputapu tuku raka hau nui tēnei mō ngā pūkohu puehu, ngā pūnaha kawe pungarehu hau, ngā oumu whakarewa, ngā whare tahu para me ngā raina whakaputa paura rauemi hanga. He rite ki ngā taupoki o runga me raro hei whakatuwhera me te kati, ka noho hiri tonu tetahi taupoki i te wā e tukuna ana. Ka ārai te hoahoa i te rere o te hau, ka taea te tuku tonu i te pungarehu me te pupuri i te pēhanga kino o te pūnaha, ā, ka ārai i te rere whakawhiti me te ngaronga pēhanga o te hau paru.

He tino kaha te āhua o tēnei tauira DN150. He mea hanga te tinana takirere mai i te maitai waro Q235B, he kaha te hanganga me te kaha ārai-horo i te puehu. Mā ngā mata hiri o ngā taupoki kua oti te whakarite kia pumau te mahi me te roa o te ora ratonga. He pai mō te pungarehu maroke, te paura kohuke, te puehu paipa me ētahi atu rauemi kirikiri maroke, ka tautoko te takirere i te mahi aunoa tonu mō ngā raina whakaputa ahumahi.

He whānuitia te whakamahinga o te takirere i roto i te tango puehu hiko wera, te hanga sima, te mahi whakarewa, te tahunga para totoka me ngā kaupapa kohikohi puehu matū, ko ngā mahi matua o te takirere ko te tukunga pungarehu me te hiri i te hau. He maha ngā wā ka turuturu te hau i ngā takirere tukunga paparua kotahi, ka whakaiti i te pai o te kohikohi puehu. Ko te hanganga raka hau paparua-rua ka whakakore i ngā tūponotanga turuturu hau kia mau ai te mahi pumau o te pūnaha tango puehu katoa.

Ka tirotirohia ngā takirere tukunga pungarehu paparua kua oti katoa e te wheketere paerewa, tae atu ki ngā whakamātautau huringa pana, te kimi hau mārō me te tirotiro pēhanga. Kei te wātea ngā ataata whakamātautau katoa hei arotake mā te kiritaki. Ka whakaratohia e mātou ngā takirere tukunga paura ahumahi me te raka hau, ā, ka tautokohia hoki ngā rahi me ngā rauemi kua whakaritea mō ngā takirere tukunga pungarehu paparua. Ka manaakitia ngā pātai mai i ngā hoa hangarau.
