1. Mō te keri kohatu hou kua hokona, nā runga i ngā mahi tiaki o te takai, ka tāpirihia he hinu ārai-waikura ki roto. Kia tino wetewetehia, kia tangohia atu hoki i mua i te whakamahinga, ā, pania ki te hinu whakahinuhinu ngā wāhanga neke katoa ina utaina anō. I mua i te mahi, me whakamātau i te hau iti, kia mōhio ai mēnā kei te mahi noa.
2, i te nuinga o te wā, i roto i te wiri ki te werohanga hinu aunoa kia whakakapia i ia wā, ko te taputapu hou kua hokona ko te werohanga i tetahi nui o te hinu whakahinuhinu, me horoi te hinu whakakī i roto i te ipu me nga mahi tiaki, hei aukati i etahi poke ki roto i te ipu.
3, me āta tirohia te wāhi e pā ana te pēhanga hau me te pēhanga wai. Ko te nuinga o te wā, ko te awhe pēhanga hau o te wiri hau whai tohu ko te 0.4-0.6mpa. Ki te nui rawa te pēhanga hau, ka tere ake te kino o ētahi wāhanga hurihuri o roto, ki te iti rawa te pēhanga, ka whakaitihia te pai o te keri, ā, ka waikura pea ngā wāhanga taputapu.
4, me aro nui te whakamahinga o te tūhono ki te mea kei te hua te tiwhikete tohu, me ārai te whakamahi i te tūhono kore tohu, hei ārai i ētahi aituā hanga.
5, me aro nui ki te hiri i roto i te hononga o ngā paipa hau me ngā paipa wai, kia kore ai e wetekina te pakitara o ngā paipa, kia kore ai hoki e whara.
6. Hei whakamutunga, me tirotiro tika te taha waho o te keri hei tirotiro mēnā he turuturu hinu, he mahi hē rānei. Mēnā ka kitea he raruraru, me whakatau wawe tonu.
