I roto i te awheawhe Jinbin, kua oti pai te hanga i tētahi puranga o ngā takirere hau kowiri tira kounga teitei 304. Nā te kowiri tira 304, me tana mahi tino pai, ka puta te hauāraihe maha ngā painga nui o te takirere.

Tuatahi, he tino pai te ātete o te kowiri tira 304 ki te waikura. Ahakoa i roto i te taiao makuku, i te hau paku waikura rānei, ka taea e ia te ātete pai ki te pirau, ka roa ake te ora o te takirere whakamātao me te whakaiti i ngā utu tiaki. He tino kitea hoki tōna ātete pai ki te pāmahana teitei, i ētahi wāhi he teitei ake te pāmahana, ka taea tonu e ia te mahi pumau hei whakarite i te mahi noa o te pūnaha hauhautanga. He kaha teitei te takirere hau kowiri tira 304, he hanganga pumau, ā, ka taea te tu atu ki te pēhanga nui ake hei whakarite kia kore e puta he whakarerekētanga me ētahi atu raruraru i raro i ngā āhuatanga mahi uaua.

I roto i ngā mahi whaihua, he maha ngā mara e kitea ai te takirere pūrerehua ārai waikura kore waikura 304. I roto i te pūnaha whakapūhautanga o te whare, ahakoa he whare noho, he whare tari, he toa hokohoko, he hōtēra me ētahi atu whare nunui, he mahi nui tāna ki te whakahaere tika i te nui o te hau kia pai ai te rere me te rere o te hau o roto. I roto i te mara ahumahi, pērā i te awheawhe matū, nā te noho mai o ngā hau waikura maha, ko te takirere ārai pūrerehua ārai waikura kore waikura 304 me tōna ātete ki te waikura, ka noho hei whiringa pai mō ngā pūnaha whakapūhautanga; I roto i te awheawhe tukatuka kai, ko ōna āhuatanga hauora me te ātete ki te waikura e tutuki ana i ngā whakaritenga taiao whakaputa tino pakari. I roto i te rūma ma o te umanga rongoā, ka whakarite i te kounga me te ma o te hau o roto, ā, ka whakarato i ngā āhuatanga taiao pumau mō te hanga rongoā me ētahi atu hononga.

Me mōhio ki te takirere hau kowiri tira i te wā e tāuta ana:

① Kōwhiringa tūranga tāutanga:

I te nuinga o te wā, kaua e iti iho i te 300mm te tawhiti i waenga i te takirere hau me te pakitara, i ētahi atu arai rānei, kia pai ai te tiaki me te whakatūnga i muri mai. I taua wā anō, kaua e tāuta ki ngā wāhi e tino wiri ana, e ngāwari ana rānei ki te pakaru ā-ringa.

② Aratau hononga:

I te wā e hono ana ki te paipa, kia tino piri te hononga kia kore ai e turuturu te hau. I te wā e hono ana i ngā flanges, tāutahia ngā gaskets hiri i waenganui i ngā flanges. Me papatahi ngā gaskets, kia kore hoki e pakaru, ā, me whakakī ōrite ngā pūtu kia kore ai e rerekē te āhua o te takirere hau, e turuturu rānei te hau nā te kaha kore taurite. Mō ngā takirere hau he nui ngā diameter o ngā paipa, me aro hoki ki te tautoko o ngā paipa kia kore ai e nui ake te pēhanga o ngā takirere hau nā te taumaha o ngā paipa.

③ Te ahunga tāutanga:

Tāutahia kia rite tonu ki te ahunga rere o te hau kua tohua e te takirere hau hei whakarite kia maeneene te rere o te hau, ki te kore ka pā ki te mahi noa o te takirere hau me te pānga whakapūhaumāota o te pūnaha.

④ Tāutanga o te pūwhakaoho:

Mena he pūwhakaoho kei te takirere hau, pērā i te pūwhakaoho hiko, hau rānei, tāutahia kia pūmau, kia ngāwari hoki te mahi. Me ngāwari te hono me te whakatika i te tūnga tāutanga o te pūwhakaoho, ā, me mahi ngā mahi tiaki hei ārai i te ua, te puehu, me ētahi atu mea e uru mai ana.
