Kei a koe i mua i tēnei i whakaaro mai ai he aha te mea e mahi ai ngā putunga nui wehe noa, pūkai, me ngā pūnaha? Nō reira, ko ngā pūnaha whakamahere nui nei i te kawe, i te kawe i ngā matū, i te kotuku o ngā poaka, me etahi atu. Ko te kaiwhakapū teka hīrahi he tūtohunga nui kē o te pūnaha i te whakarite i te nui o te kaihīrahi e whati ana i runga i tētahi pūnaha, me te nui o tana aronga ki te mahi o tētahi pūnaha.
U hydraulics hei waiū tētahi whakamārama i whakamahi ai ki te whakatutuki i ngā mahi o ngā mīhini. Hei tauira, ka whakarerekē ngā rae me te kete o tētahi whakarere whenua ki runga ki raro i te u hydraulics. Ko tēnā e ārao ana kia unuwha i te one me te kawe i ngā taumata nui. Kāore i ngā pūtango pausa hydraulics, ka ātiaki te wai kia motuhake rawa atu koia ki te motuhake iti. Ki te hē ki te torotoro, ka weriweri te mīhini me te kitea he rereke. Ki te hē ki te torotoro iti, kāore te mīhini i tana mahi. Ko tēnei te take i te mea he hiahia ki ngā mīhini ki te omm 32 hydraulic motor , me whakaae atu ki a rātou kia mahi pai rawa.
Tērā i te āka o te whakamutunga, he maha ngā wāhanga kei roto i te pūtauhere here kōhatu e āwhina nei ki tēnā. E hī ai i te tinana o te pūtauhere me te kaiwhiuwhiu e noho ana ki runga i te pihikara. Kia tae mai te wai ki te tinana o te pūtauhere, ka mahi ngā kaiwhiuwhiu me te pihikara i roto i te pūtauhere hei whakawehe i te nui o te wai e whai ake nei i te hokinga. Ki te nui ake rawa atu te huakere o te wai, ka taipitohia e te pihikara i te pūtauhere. Ka whakaheke i te āhuatanga o te hokinga o te wai i roto i te rorohiko hei whakarite i ngā mea katoa i te tika tonu.
He whakangākau nui, he whai take ki te whakamahia i te wehi o te hunga me te rorohiko. Ahakoa, ka tiakina anō e ia te tūrupeke i te whakapakarupeke. Ki te kore he pūtauhere here kōhatu, he nui rawa atu te huakere i roto i te tinana. Ka kitea he mea e taea ana te whakapakarupeke i ngā hurihanga riro rānei i te rorohiko. He mea nui rawa atu ngā pūtauhere here kōhatu ki te whakatūpūtia i te wehenga i te huakere me te hokinga o te wai kōhatu hei whakarite i te whakatipuranga me te wehi o ngā rorohiko.
Ā rānei, ina whai pūmanawa hoki me te tino āhua pai o ngā whakawhitinga, ka puta ngā take i roto i ngā hauwhakaminitanga puhipuhi. Take anō he mea ko te mea ka noho pū i runga i tētahi wāhi whakamutunga. Ko tēnā e whakaaturia te kuhu atu o te mimi puhipuhi ki runga i te whakahuatere. Ki te koe i tēnei wā, ko te mea tuatahi hei whakatū i a koe he tirotiro i te pūmanawa, kia kite ai i te mea he pū whenua kei roto i te pūmanawa. Ka noho pū manawa āpōpō nā ngā kereka, oneone, rānei ko ētahi atu momo hua, e hiaia ana kia kore e mahi tonu i te tika.
He pai anō hoki tētahi pūmanawa puhipuhi pai ki te whakawhanake i a koe i te pai me te taea ai e koe te whakaritea i te oranga ake o tō whakahuatere. Ko te pūmanawa e mahi nei i tana mahi i te whakahē i te kino kia kaua e tae mai, ā, e tūtonu ana i te whakamahere i te mimi puhipuhi kia noho i tana aratohu pai rawa. Nō reira, ko tēnei whakahaere e iti ana i ngā whakatikatika kaha, ā, e manaaki ana i te whakahuatere kia ora tonu mo te wā e hirari ana.
He mea nui te whakahaere tika me ngā whakamatau i roto i te wā mō te whakarite i te kaiwhakapū teka hīrahi i roto i tētahi āhuatanga pai. Tētahi o ngā rautaki wae rawe hei whakamahi, ko te tirotiro i ngā taumata kaihīrahi i runga i te waenganui o ngā wā. Kaore e taea ana tō pūnaha ki te mahi pai i te nekehanga iti o te kai, nā reira ka hia atu i te wā — me te whakapai i te kai. Ahakoa iti noa iho te mahi nei; he whiu nui tēnei i runga i te mahi o tō pūnaha.
