1. Kaua e piko, kaua hoki e tūpono te nekeneke ina tāutahia te porotiti ki te pou. I roto i te huihuinga tuku kotahi, me noho ngā mata pito o ngā porotiti e rua ki te papa kotahi. Ina iti iho i te 0.5m te tawhiti pokapū o ngā porotiti, ko te rerekētanga e whakaaetia ana ko te 1mm; ina neke atu i te 0.5m te tawhiti pokapū o te porotiti, ko te rerekētanga e whakaaetia ana ko te 2mm. Heoi, kāore e whakaaetia te waku i te taha o ngā niho porotiti. Mena ka nui rawa te neke o ngā wira e rua, ka ngāwari te wehenga o te mekameka me te tere o te pakaru. Kia tupato ki te tirotiro me te whakatika i te rerekētanga ina whakakapia te porotiti.
2. Ki te tino piri rawa, ka nui ake te kaha e pau ana, ā, ka ngāwari te pakaru o te peera; ki te tino wetekina, ka ngāwari te peke me te tango i te mekameka hiki. Ko te piri o te mekameka hiki: hikitia, pēhia rānei mai i waenganui o te mekameka, ko te tawhiti pokapū o ngā porotiti e rua he 2% - 3%.
3. Ko ngā mea kua whakamahiamekameka hikikāore e taea te whakaranu ki ētahi mekameka hou, ki te kore ka ngāwari te pānga ki te tuku me te motu i te mekameka.
4. I muri i te pakaru kino opūwero, me whakakapi te porotiti hou me te mekameka hou i te wā kotahi kia pai ai te hononga. Kāore e taea te whakakapi motuhake i tētahi mekameka hou, i tētahi porotiti rānei. Ki te kore, ka kino te hononga, ā, ka tere ake te pakaru o te mekameka hou, o tētahi porotiti rānei. Kia pakaru te mata o te niho porotiti ki tētahi taumata, me huri i te wā tika (e pā ana ki te porotiti me te mata ka taea te whakarerekē). Hei whakaroa i te wā whakamahinga.
5. He roa rawa, he totoro rawa rānei te mekameka hiki hou i muri i te whakamahinga, he uaua ki te whakarite. Ka taea te tango i ngā hononga mekameka i runga i te āhuatanga, engari me ōrite te maha o ngā hononga mekameka. Me haere te hononga mekameka mā te tuara o te mekameka, me whakauru te wahi raka ki waho, ā, ko te whakatuwheratanga o te wahi raka me huri ki te taha ke o te hurihanga.
6. Me whakakī te mekameka hiki ki te hinu whakahinuhinu i te wā tika. Me tomo te hinu whakahinuhinu ki te āputa i waenganui i te roera me te ringaringa o roto kia pai ake ai ngā āhuatanga mahi me te whakaiti i te kakahu.
