Whakaahuatanga o te Mīhini DAF
Ko te mīhini DAF he mea hanga i te pūnaha whakapūtanga hau rewa, te pūnaha waru me te mana hiko.
1) Pūnaha whakamānu hau rewa: Mā te papu rere whakamuri mai i te tāke wai ma e whāngai te wai mā ki roto i te tāke hau rewa. I taua wā, pēhia te hau e te pēhi hau ki te tāke hau rewa. Tukua ki roto i te tāke i muri i te whakaranu i te hau me te wai e te kaiwhakarewa.
2) Pūnaha waru: waruhia te paru e mānu ana i runga i te wai ki roto i te tāke paru
3) Mana Hiko: Mā te mana hiko ka eke te mīhini DAF ki te hua pai rawa atu

Tono
Ka taea te whakamahi i te mīhini whakapūmau penei:
1) Wehea te mea iti e iri ana me te rimurimu mai i te wai mata
2) Tangohia ngā mea whai hua mai i te wai para ahumahi. Hei tauira, ko te penupenu
3) Hei utu mō te wehenga tuarua o te tāke whakapūtātanga me te paru o te wai kukū

Kaupapa Mahi
Ka tukuna te hau e te pēhi hau ki roto i te tāke hau, kātahi ka tangohia te hau rewa i roto i te tāke mā te pūrere rere jet, ka kaha te hau ki te rewa ki roto i te wai i raro i te pēhanga 0.35Mpa ka hanga he hau rewa wai, kātahi ka tukuna ki te tāke whakamānu hau.
I raro i te tukunga ohorere, ka memeha te hau i rewa i roto i te wai, ka hanga he rōpū mirumiru nui, ka tino pa atu ki te mea iri e rere ana i roto i te wai para. Ka tukuna te mea iri mā te papu me te rere i muri i te tāpiri i te rongoā. Ka mimiti te rōpū mirumiru e piki ake ana ki roto i te mea iri kua rere, ka whakaitihia tōna matotoru, ka mānu ki te mata o te wai, ā, ka tutuki te kaupapa o te tango i te SS me te COD.
