Mā te whakakā korehau ka taea te hono i ngā rauemi mā te whakamahi i tētahi rauemi whakakī kāore e hiahiatia he rerenga motuhake hei ārai i ngā waikura. Mā te pupuri i tētahi rerenga puta noa i te whakakā ka mahi te nuinga o te mahi ki te ārai i te hāora kia kore e uru ki te tukanga. He mea nui tēnei mō ngā kiritaki he wāhanga tino motuhake kei reira ngā matū, ngā konganuku rānei kei roto i te rerenga ka hanga i ngā poke kāore e hiahiatia i roto i te hononga whakamutunga. Ka hua ake he wāhanga tino ma.
Nā te mea kua hangaia ngā oumu korehau me te whakaaro ki te whakahaere pāmahana, e mōhio ana ngā tohunga whakarewa ka taea e te oumu korehau te whakamahana i te rauemi whakakā me ngā wāhanga hei hono me te tika, te ōrite, me te ngāwari ki te whakahoki. Ko ngā wāhanga he uaua te hoahoa e hiahia ana kia honoa ki ngā wāhi uaua ki te tae atu, ki ngā huihuinga rānei he maha ngā hononga ka ngāwari ake te whakakā i roto i te taiao oumu korehau.
He mea tino pai hoki te whakakā korehau ina hiahiatia kia honoa ngā wāhanga e rua he angiangi rawa, he matotoru rawa rānei, me te hanganga pakari. Ko ngā wāhanga angiangi e whakawhirinaki ana ki te whakahaere pāmahana tika kia kore ai e piko, ko ngā wāhanga matotoru ake ka whakawhirinaki ki te aroturuki i te thermocouple kia tika ai te wā rumaki, kia rite ai te whakamahana i te wāhanga.
Mā te whakahaere i te āhuarangi me te pāmahana e kitea ana i roto i te oumu korehau ka taea te whakarite i te pāmahana ōrite mō ngā wāhanga he mata uaua. Mā te whakamahana me te tinei i ngā wāhanga i te tere e taea te matapae, ka whakaratohia e te oumu korehau he mana whakahaere tino pai ki te huri i te koranu whakawera ki te wai i te pāmahana e kore e huri, e whakapohehe rānei i ngā wāhanga hei hono.
Ko tētahi atu painga nui o te whakamahi i te otinga whakakoi korehau ko te kaha ki te whakahaere i ngā hua o te tukanga. He pai ake te whakahaere me te tukatuka i te hauhautanga i te kaukau tote rite, i te otinga hau rānei, ā, kāore e hiahiatia he matū kino, he tote rewa rānei e hiahia ana kia ata puritia, kia maka atu hoki. Kāore e hiahiatia he horoinga wāhanga tukatuka-muri mō ngā tunu whakakoi korehau ma, ā, ka whakaitihia hoki te para matū.
