Tuatahi, whakamahana:
1. Mo te mea mahi he ahua uaua, he rereke ranei te waahanga whakawhiti me te matotoru whai hua nui, me whakamahana.
2. Ko te tikanga o te whakamahana: he whakamahana mo te 800 ℃, ko te whakamahana tuarua ko te 500 ~ 550 ℃ me te 850 ℃, me iti te tere o te piki o te pāmahana o te whakamahana tuatahi.
Tuarua, whakawera:
1. He kakari me nga kohao kei roto i te taputapu mahi, te whakarewa me te whakapiri i nga waahanga me nga taonga mahi kowiri tira, te tikanga kaore i roto i te whakamahana oumu pati tote.
2. Me whakarite kia whakamahana te taputapu mo te wa tika.Tātaihia te matotoru whaihua o te mea mahi me te matotoru here (te tino matotoru kua whakareatia ki te whakarea ahua o te mea mahi) ma te titiro ki te Ripanga 5-16 me te Ripanga 5-17
Tuatoru, horoi:
1. Ko te mahi me te taputapu me whakakore i te hinu, te toenga o te tote, te peita me etahi atu mea ke i mua i te maimoatanga wera.
2. Ko te taputapu i whakamahia mo te wa tuatahi i roto i te oumu korehau kia whakakorehia, ka purea i mua i te iti rawa i raro i te tohu korehau e hiahiatia ana e te taputapu mahi.
E wha, te uta umu:
1. I roto i te tukanga o te maimoatanga wera, me whakawerahia te waahanga mahi whakaheke i runga i tetahi taputapu motuhake
2. Me whakanoho te mea mahi ki tetahi rohe whakamahana whai hua
