Kāore te Pūwhakatuwhera Kōhao e whakamahia ana i roto i te Keri Aronga Whakapae (HDD) e "keri i tētahi kōhao hou mai i te tīmatanga". Engari, e whai ana i tētahi tukanga e toru ngā taahiraa: tuatahi te keri i tētahi kōhao iti, kātahi ka whakamahi i te pūwhakatuwhera kōhao hei whakawhānui haere i te kōhao ki te diameter kua hoahoatia, ā, hei whakamutunga ka hutia te paipa. He whānui te whakamahinga o tēnei hangarau kore-keri i roto i ngā kaupapa whakatakoto paipa, ā, ka ārai i te kino ki te mata o te whenua, ki ngā rori, me ngā whare.
1. Keria te Kōhao Paerata i te Tuatahi
① Ka keria e te taputapu keri he kōhao iti te whānui (φ80–200mm) i te pūwāhi tomo e ai ki te ara kua hoahoatia. ② Ka whakamahia te mata keri, te pūwero, me te piko raro (1°–2°) hei whakatakoto, hei hurihuri me hei neke whakamua i te wā e keri ana. Ka whakamahia te paru hei whakamatao, hei kawe i ngā tapahi, hei tiaki i te pakitara kōhao. ③ Keria kia tae rā anō ki te pūwāhi putanga hei whakaoti i te urunga o te kōhao.
2. Whakakapia ki te Pūwhakatuwhera Kōhao mō te Whakahoki Whakamuri
Tangohia te mata keri pairati i te pito putanga ka hono atu ki te Whakatuwhera Pōka HDD, kātahi ka mahi i te whakahurihuri takahanga-i-te-taahiraa. ① Hanganga: Kei roto i tēnei he tinana pokapū, he mata/kone roera ka taea te whakakapi, me ngā pūwero. E toru ngā momo: momo waru (mō te oneone ngohengohe), momo kone roera (mō te toka), me te momo whakakotahi (mō ngā hanganga uaua). ② Mātāpono Mahi (Matua): Ka huri te taputapu keri, ka tōia whakamuri, ka tapahia, ka pēhia, ka kuruhia e ngā mata/kone roera te pakitara o te poka, ka whakawhanui i te poka pairati φ200mm ki te φ600–1500mm. Ka whakamataohia ngā taputapu tapahi e te pupuhi paru pēhanga teitei, ka haria ngā tapahi ki muri, ā, ka tiakina te pakitara o te poka kia kore ai e hinga. ③ Whakahurihuri Maha-Wāhanga: Hei tauira, φ200→φ400→φ600→φ800. Ka whakawhanuihia ia whakahurihuri kotahi te taumata kia kore ai e hinga te poka.
3. Te Hanganga o te Kōhao me te Hokinga Whakamuri o te Paipa
① Ko te whānui o te kōhao whakamutunga he ≥1.5 ngā wā o te whānui o te paipa (hei tauira, te paipa φ610mm → te kōhao ≥φ915mm). ② I muri i te horoinga o te kōhao, honoa te hononga hurihuri me te paipa hei whakatakoto ki muri i te whakatuwhera kōhao, kātahi ka tōia te paipa ki roto i te kōhao hei whakaoti i te whakatakoto.
