Ko te motokā hōu tētahi huinga matatini o ngā wae, engari ko ētahi wae he mea matua whakahaere i te haumātauranga, te mahi, te pono, me te whakahaere i ngā rīwhi; ka hangaia ēnei wae ki ngā paerewa matatau rawa, ki te roa hoki o te wa. Ko te pouaka mōhinu me te upoko siliara te kiko o te punaha herehere; ēnei hinga nui (he nui ake i te paraihe, he nui ake i te rino hoki) e mātai ana i ngā siliara, te rākau pūkaha, me te rākau tapatoru, ā, ka mātai i ngā inenga kia pai ai te whakapaku, te whakapai, me te whakamaroke. Ko te punaha whakawhiti, heoi anō ko te takirua, heoi anō ko te tūmatanui, kei roto he tauira o ngā wae matua pērā i ngā tarau, ngā rākau, me ngā paparorotau, me hangaia ki te pūkaha tino nui me te tika o te āhua kia taea ai te wehi nui, ā, kia mahi māmā, kia māma. Ko te punaha aritau he mea matua nui mō te haumātauranga, ko ana wae matua ko ngā kāpia aritau, me whakamahia kia pūmau, kia mātai hoki kia ū tonu te toki ki ngā paparorotau, me te silinda matua, e huri ana i te kaha o te karu whiu ki te kaha waimātai. Ko te knikle tirotiro me ngā taura whakahaere i roto i te punaha whakamaroke he mea matua mō te āhuatanga o te tirotiro me te reka haere; he nui ake i te hinga, he nui ake i te pāpaku, ā, ka mātai ki ngā āhua tika kia pupuri i te tika o te tūranga karu me te whakangāhau i ngā pōro. Ka tāwhai hoki ngā motokā hōu ki te Kaitiaki Mōhihi (ECU) me tētahi whatunga o ngā kaitirotiro (pērā i ngā kaitirotiro tūranga rākau pūkaha, kaitirotiro hau, me ngā kaitirotiro rere hau) e mahi ana hei pūpahi o te motokā, e tirotiro ana, e whakarerekē ana i ngā wāhi o te mōhihi mō te mahi pai rawa, mō te pono hoki. Ko te hanga tika o ēnei wae matua o te motokā, he nui ake i ngā tikanga matua pērā i te CNC, te whakapai, me te whakamaroke, he mea kore e taea te whakakore. Ko te mahi pono o ēnei wae e whakarātangia ana kia pai ai te mahi o te motokā, te whai moni hoki, engari ko te mea matua nui, ko te haumātauranga o ngā kainoho, o ngā kaiwhakamahi huarahi hoki, ka whakaatu i te aronga tuuturu o te ahumahi motokā ki te kounga, ki te pūkenga tika hoki.
