Ko te rīpene huna whakapae e pā ana ki te āhuatanga e huri ana te rahi o te koropiko i te wā e whakahaerehia ana te mīhini whatu porohita mō te wiki kotahi, ā, ka puta he koretake me te kore taurite i runga i te mata o te papanga.

Take

I raro i ngā āhuatanga noa, ko te putanga mai o ngā rārangi huna whakapae nā te miihini, nā ētahi wāhanga rānei, ka puta ai te totoro kore taurite o te miro i ia wā, ka hua ake he panoni i te rahi o ngā koropiko, tae atu ki ēnei āhuatanga matua:

1. Kāore i te rawaka te tika o te mīhini whatu porowhita ina tāutahia, kua tawhito haere te mīhini whatu porowhita, ā, ka nui te pakaru, ā, ko te taumata, te kōpikopiko me te porowhita o te rango ngira (mata) kua nui ake i te awhe manawanui e whakaaetia ana;

2. I te wā e whakahaerehia ana te mīhini whatu porowhita, kei roto i te poraka reti i roto i te paepae whāngai miro ngā paru me ētahi atu paru, ka puta he tuku whitiki rerekē, ka hua ake he whāngai miro kore pumau;

Otinga

A. Te whakakikorua i te mata o te pereti taputapu ki te hiko, me te whakamātotoru kia tika ai te whakahaere i te āputa o te pereti taputapu i waenga i te 0.1 me te 0.2mm.

B. Whakakanapahia te ara pōro rino o raro, tāpirihia he hinu, whakahāngaihia te raro o te rango ngira ki te gasket ngawari, angiangi hoki, ā, whakahaerea te āputa porowhita o te rango ngira ki te 0.2mm pea.

Me whakatikatika tonu te kāme totohu kia mōhio ai kei waenga i te 0.3 me te 0.5mm te tawhiti i waenga i te kāme totohu me te pito totohu kia rite tonu ai te kume o te miro i te wā e wetewete ana i te koropiko.

F. Ka whakamahia te mita kume hei ine i te kume whāngai miro kia rite ai te kume whāngai miro o ia ara.

I roto i te mahi whatu, nā te rerekētanga o te hanganga o te papanga, ka rerekē anō hoki te puta o ngā rīpene huna whakapae. I te nuinga o te wā, he mārama ake ngā papanga kotahi-hāte i ngā papanga takirua-hāte.

Hei tāpiritanga, ko te iti rawa o te pēhanga o te ngira i te tatau te take o te rīpene huna whakapae. Me whai momo papanga motuhake ētahi tawhā papanga. Ka tino whakatikatikaina te ngira pēhi o te ngira i te wā e whatu ana, ā, me whakatikatika anō hoki te ngira e mānu ana i te tatau. Nō reira, kia aro ki te tūranga o te ngira i te tatau ina whakawhiti momo.
