Kua wehea te paera awhina ki nga momo e rua: te mahi tika me te mahi pairati.

Ko te kaupapa mahi o te reera awhina tika:

Ko te paera whakaahuru mahi tika he reera awhina e taurite tika ai te pehanga o te punaha e mahi ana i runga i te poka me te pehanga o te puna.Ko te tukanga motuhake o te paera awhina ki te pupuri i te pehanga o te punaha tata tonu ko: I te wa e pai ana te mahi o te reera awhina, ka taurite te porowhita ki te waahi tuwhera e pai ana ki te rere o te waipuke.Ka nui ake te pehanga o te punaha i te uara tautuhinga o te rewharewha awhina, ka piki ake te pana waipēhi e pana ana i te porowhita ki runga, ka ngaro te toenga taketake ka neke ake te potae, ka piki te rahinga whakatuwhera δ, ka heke te parenga wai, ka piki te rere o te waipuke, ka heke te pehanga o te punaha ki te uara tautuhinga.Ka iti ake te pehanga o te punaha i te uara kua whakaritea o te paera awhina, ka iti ake te pana waipēhi e pana ana i te spool ki runga, ka heke iho te spool mai i te turanga taketake i raro i te mahi a te kaha o te puna, ka heke te rahinga whakatuwhera δ, te aukati wai. ka piki ake, ka heke te rere o te waipuke, ka piki aunoa te pehanga o te punaha, ka hoki tata ki te uara kua whakaritea.No reira, i te wa e mahi ana te rewharewha mahi tika, ka neke ake te hikoi ki raro me te huringa o te pehanga o te punaha, kia mau tonu ai te pehanga o te punaha.

Te kaupapa o te paera awhina a te kaiurungi: Ko te paera e whakahaeretia ana e te kaiurungi he maera awhina e whakamahi ana i te paera pairati ki te whakaiti i te pehanga me te whakahaere i te waipuke o te maataki matua.

Ma te paera awhina i roto i te punaha waipēhi, kaore e taea e te pehanga o te punaha te neke atu i te pehanga kua whakaritea e te paera awhina, na reira ka whai waahi te maataki awhina ki te aukati i te taumaha o te punaha.Mena ka whakamahia te paera awhina hei paera haumaru, ko te pehanga tepe i te wa e taumaha ana te punaha me whakamahia hei pehanga tautuhinga o te paera.Ko te taumahatanga ina whakatuwherahia te tauranga takirere, ka hoki ano te hinu ki te tank, he mahi tiaki haumaru.I te nuinga o te wa ka kati te paera haumaru i te wa e mahi ana te punaha.
