Ka whakawhirinaki te pūwero whakamātao piston rūma makariri ki te nekehanga tauutuutu o te piston hei pēhi i te hau i roto i te rango. I te nuinga o te wā, ka hurihia te nekehanga hurihuri o te neke matua hei nekehanga tauutuutu o te piston mā te pūnaha hononga-porotaka. Ka taea te wehewehe i te mahi a te porotaka porotaka i ia hurihanga ki te tukanga momi me te tukanga pēhi me te whakaputanga hau.
I roto i te whakamahinga o ia rā o ngā pūwero whakamatao piston, e 12 ngā hapa noa me ā rātou tikanga whakatau raruraru kua whakarōpūtia penei:
1) He nui te hinu e pau ana i te compressor
Take: He nui rawa te āputa i waenganui i te peera, te mowhiti hinu, te rango me te piston, ka nui ake te whakapaunga wahie.
Rongoā: Whakahaerehia ngā mahi tiaki e tika ana, whakakapia rānei ngā wāhanga.
2) He teitei rawa te pāmahana o te peera
Ngā Take: Hinu paru, arai te huarahi hinu; kore rawa te hinu e tukuna; iti rawa te āputa; pakaru rerekē o te peera, taratara rānei te rakau peera.
Whakakorenga: Horoia te ara iahiko hinu, whakawhitihia te hinu whakahinuhinu; whakaratohia he hinu e ranea ana; whakatikahia te āputa; whakahoutia te rakau peera.
3) Kāore i angitu te tikanga whakahaere pūngao
Take: Kāore i te rawaka te pēhanga hinu; kei roto i te hinu he wai whakamatao; kua paru, kua āraia hoki te takirere putanga hinu o te pūnaha whakahaere.
Whakakorenga: Kimihia te take o te iti o te pēhanga hinu, ka whakatikatika i te pēhanga hinu; whakamahanahia te hinu i roto i te pouaka miihini mō te wā roa; horoia te ara iahiko hinu me te takirere hinu kia kore ai e araia te ara iahiko hinu.
4) He tino teitei rawa te pāmahana o te hau whakaputa
Ngā take: he nui te kawenga; he nui rawa te āputa; kua pakaru te takirere me te gasket putanga; he nui te wera o te momi; he ngoikore te whakamatao o te rango.
Whakakorenga: whakaitihia te kawenga; whakatikahia te āputa ki te gasket rango; whakakapia te pereti paepae, te gasket rānei i muri i te tirotiro; whakanuia te nui o te wai; whakanuia te nui o te wai whakamatao.
5) He iti rawa te pāmahana o te hau whakaputa
Ngā take: ka mimiti te wai i te pūwero; he nui rawa te wai e tukuna ana e te takirere whānui; kāore i te rawaka te kawenga whakamatao; he matotoru rawa te hukapapa o te pūwero.
Te Whakakorenga: whakaitihia te whakatuwheratanga o te takirere momi; whakarerekētia te rere o te wai kia wera rawa te hau hoki mai i waenga i te 5 me te 10; whakarerekētia te kawenga; horoia, horoia rānei te huka i ia wā.
6) He nui rawa te pēhanga o te hau whakaputa
Take: Ko te raru matua ko te pūwhakamātao, pērā i te hau kāore e taea te whakamātao i roto i te pūnaha; kei te tuwhera te takirere wai δ, kāore rānei i te nui te whakatuwheratanga, he iti rawa te pēhanga wai kāore e ranea te wai, he teitei rawa rānei te pāmahana wai; kei te tuwhera te pā whakamātao hau δ, kāore rānei i te ranea te rahinga hau; he nui rawa te utu hauhautanga (inā kāore he kaiwhiwhi wai); he nui rawa te paru i roto i te pūwhakamātao; kua tuwhera te takirere putanga hau δ ki te mōrahi} Kāore te paipa putanga i te maeneene.
Te Whakakorenga: whakahekehia te pito o te putanga hau pēhanga teitei; whakatuwheratia te takirere wai hei whakanui ake i te pēhanga wai; tahurihia te pā hau hei whakaiti i te ātete hau; tangohia te hau whakamatao taikaha; horoia te pūwhakamātao me te aro ki te kounga o te wai; whakatuwheratia te takirere putanga; whakawāteahia te paipa putanga.
7) He iti rawa te pēhanga o te hau whakaputa
Ngā Take: Kāore i te rawaka te hau whakamatao, te turuturu rānei; te turuturu o te hau mai i te takirere putanga; te nui rawa o te wai whakamatao, te pāmahana wai iti, me te whakahaere koretake o te pūngao.
Te whakakore: te kimi me te whakakore i ngā turuturu, te whakakī anō i te hauhautanga; te whakatika, te whakakapi rānei i ngā poro takirere; te whakaiti i te wai whakamatao; te whakatika i ngā taputapu whakahaere hiko
8) Te pēhi mākū (te hama wai)
Ngā Take: He nui rawa te taumata wai o te mīhini whakapūhau; he nui rawa te kawenga; he tere rawa te whakatuwheratanga o te takirere momi.
Te whakakorenga: whakatikatikahia te takirere tuku wai; whakatikatikahia te kawenga (whakatikahia te taputapu whakatikatika pūngao); me whakatuwhera mārire te takirere momi, ā, me kati mēnā he hama wai.
9) He teitei rawa te pēhanga hinu
Take: Kāore i te tika te whakarerekētanga o te pēhanga hinu; te paipa hinu ngoikore; te ine pēhanga hinu kāore i te tika.
Rongoā: whakatikatika anō i te takirere pēhanga hinu (whakangāwarihia te puna); tirohia, horoia hoki te paipa hinu; whakakapia te ine pēhanga
10) He iti rawa te pēhanga hinu
Ngā Take: Kāore i te rawaka te hinu; te whakarerekētanga hē; te tātari hinu kua purua, te tomokanga hinu rānei kua purua; te pakaru o te papu hinu; te mahi korehau (whakapūhaumāota).
Rongoā: tāpirihia te hinu; whakarerekētia te takirere whakahaere pēhanga hinu} tangohia, horoia, tangohia te aukati; whakatikahia te papu hinu; whakarerekētia te mahi kia teitei ake te pēhanga o te pouaka miihini i te pēhanga o te hau.
11) He tino teitei rawa te pāmahana hinu
Ngā take: he teitei rawa te pāmahana o te hauhautanga; kāore i te pai te whakamatao o te hinu; he iti rawa te āputa o te huihuinga.
Whakakorenga: Whakatauhia te pūtake o te pēhanga nui o te hau whakaputa; whakanuia te nui o te wai whakamatao; whakatikatikahia te ātea.
12) Te wera nui o te motuka
Ngā Take: te iti o te ngaohiko, ka hua ake he iahiko nui; te koretake o te hinu whakahinuhinu; te nui rawa o te mahi; te hau kore e taea te whakapūtā i roto i te pūnaha; te kino o te whakamarumaru o te takai hiko.
Te Whakakorenga: tirohia te pūtake o te ngaohiko iti, ā, whakakorea; tirohia te pūnaha whakahinuhinu, ā, whakaotia; whakaitihia te kawenga; tukuna te hau kore-whakapūtā; tirohia, whakakapia rānei te motuka.
