HewhakawhitiHe wāhanga hikohiko e whakamahi ana i ngā mātāpono hikohiko, i ētahi atu pānga ā-tinana rānei, hei whakatutuki i te "whakakā/whakaweto aunoa" o ngā ara iahiko. Ko tana mahi matua he whakahaere i te whakakā-whakaweto o ngā ara iahiko nui/ngaohiko teitei me ngā iahiko/tohu iti, me te whakatutuki hoki i te wehenga hiko i waenga i ngā ara iahiko hei whakarite i te haumaru o te pito whakahaere.

Ka taea te wehewehe i ana mahi matua ki ngā wāhanga e toru:

1. Whakahaere me te Whakakaha: Ka taea e ia te huri i ngā tohu whakahaere ngoikore (pērā i ngā iahiko taumata-miliampere e tukuna ana e ngā rorohiko iti me ngā pūoko maramara-kotahi) hei iahiko kaha e ranea ana hei taraiwa i ngā taputapu mana-nui (pērā i ngā motuka me ngā whakamahana), e mahi ana hei "whakakaha tohu". Hei tauira, i roto i ngā kāinga atamai, ka taea te whakahaere i ngā tohu hiko iti e tukuna ana e ngā taupānga waea pūkoro mā roto i ngā whakawhiti hei tahuri me te whakaweto i te hiko o ngā hauhautanga me ngā rama o te whare.

2. Wehenga hiko: Kāore he hononga hiko tika i waenga i te ara iahiko whakahaere (ngaohiko iti, iahiko iti) me te ara iahiko whakahaere (ngaohiko teitei, iahiko nui). Ka tukuna noa ngā tohutohu whakahaere mā roto i ngā tohu hikohiko, i ngā tohu whatu rānei hei ārai i te urunga o te ngaohiko teitei ki te pūmau whakahaere, ā, ka kino te taputapu, ka tūpono rānei ki te haumaru o ngā kaimahi. He mea noa tēnei i roto i ngā ara iahiko whakahaere o ngā mīhini ahumahi me ngā taputapu hiko.

3. Arorau me te Parenga: Ka taea te whakakotahi hei whakatinana i te arorau ara iahiko matatini, pērā i te raka (te aukati i ngā motuka e rua kia tīmata i te wā kotahi) me te whakahaere whakaroa (te whakaroa i te hononga o te kawenga mō tētahi wā i muri i te whakakā). Ka taea hoki e ētahi whakawhiti motuhake (pērā i ngā whakawhiti iahiko nui me ngā whakawhiti wera nui) te aroturuki i ngā hapa o te ara iahiko. Ina nui rawa te iahiko, ina teitei rawa rānei te pāmahana, ka tapahia aunoatia e rātou te ara iahiko hei tiaki i ngā taputapu hiko mai i te kino o te taumaha nui.
