Ngā painga o ngā ngongo whakamahana hiko maroke
1. He iti te rahinga, he nui te mana: ko te nuinga o te wā ka whakamahia te huānga whakamahana ngongo momo tautau hei whakamahana hiko o roto, ko te mana mōrahi o ia huānga whakamahana hiko ngongo momo tautau ko te 5000KW.
2. Te urupare tere ki te pāmahana, te whakahaere pāmahana tino tika, te whai huatanga wera whānui.
3. Whānui te whānuitanga o te whakamahinga, kaha te urutau: ka taea te whakamahi i te whakamahana hurihuri ki te ātete-pahū, ki ngā wā rānei, ka taea e tōna taumata ātete-pahū te eke ki te taumata B me te C, ka taea e tōna ātete pēhanga te eke ki te 10Mpa, ā, ka taea te tāuta poutū, whakapae rānei e ai ki ngā hiahia o te kaiwhakamahi.
4. Te pāmahana wera teitei: Ko te pāmahana mahi mōrahi o te whakamahana kua hangaia kia eke ki te 850°C, kāore e wātea ana mō ngā whakawhiti wera whānui.
5. Mana whakahaere aunoa: Mā te hoahoa ara iahiko whakamahana, he watea ki te whakatutuki i te mana whakahaere aunoa o te pāmahana putanga, te pēhanga, te rere me ētahi atu tawhā, ā, ka taea te hono atu ki te rorohiko hei whakatutuki i te kōrero tangata-mīhini.
6. He roa te ora, he tino pono: he mea hanga te whakamahana ki ngā rauemi whakamahana hiko motuhake, ā, he whaitake ake te kawenga mana hoahoa, he maha ngā parenga e whakamahia ana e te whakamahana, ka nui ake te haumaru me te roa o te ora o tēnei whakamahana.
7. Ko te ngongo whakamahana hiko maroke kowiri tira he ngongo whakarewa hei anga, i waenganui o te ngongo ki te waea koranu whakamahana hiko hurihuri ōrite (rori, koranu tereina) ko tōna marae kau kī tonu i te onepu konupora waikura kiato me te whakamarumaru pai me te kawe wera, ko ngā pito e rua o te waha o te ngongo me te kāpia pereki, te hiri uku rānei, ka taea e tēnei whakarewa koi te whakamahana i te hau, te pokepokea ai me te maha o ngā wai, i roto i te ngongo kowiri tira kore utu he pai te tohatoha i te waea hiko pāmahana teitei, i roto i te marae kau he pai te kawe wera me te whakamarumaru o te paura konupora waikura tioata, ehara i te mea he matatau anake tēnei hanganga, he pai te whakamahana, he rite te whakamahana, ina puta te waea ātete pāmahana teitei, ka tukuna te wera mā te paura konupora waikura tioata ki te mata o te ngongo whakarewa, kātahi ka whakawhitia ki ngā wāhanga wera, ki te hau rānei hei whakatutuki i te kaupapa o te whakamahana.
