Tirohanga Whānui

Ko te takirere pōro mānu e whakamahia ana i te nuinga o te wā mō te pēhanga waenga, iti rānei (i raro i te 900LB), ā, e 2, e 3 rānei ngā tinana. Ahakoa he māmā te hanganga o tēnei raupapa, he pono te mahi hiri.

Blkakau ārai-waho

Hei ārai i te rere o te kakau, ka hua ake te pikinga rerekē o te pēhanga o roto o te takirere, ka mau te pakihiwi ki te pito o raro o te kakau. Hei tāpiri, hei ārai i te turuturu mai i te wera o te huinga tākai o te kakau i roto i te ahi, ka whakatakotoria te peera pana ki te tūranga pa o te pakihiwi i te pito o raro o te kakau me te tinana takirere. Nō reira, ka hangaia he nohoanga hiri whakamuri hei ārai i te turuturu me te karo i te aituā.

Hoahoa haumaru-ārai-ahi

Mēnā ka pā te ahi i te wā e whakamahia ana te takirere, ka pakaru te mowhiti nohoanga o ngā rauemi kore-whakarewa i te pāmahana teitei. Ina wera te nohoanga me te mowhiti-O, ka hiritia te pupuri nohoanga me te tinana ki te karāhe haumaru ahi.

Pūrere ārai-pūmau

Kei te takirere pōro he hanganga ārai-pūmau, ā, ka whakamahia te taputapu tuku hiko pūmau hei hanga tika i tētahi awa pūmau i waenganui i te pōro me te tinana, hei hanga rānei i tētahi awa pūmau i waenganui i te pōro me te tinana mā roto i te kakau, kia taea ai te tuku i te hiko pūmau i puta mai i te waku i te wā e whakatuwhera ana, e kati ana hoki te pōro me te nohoanga mā roto i te paipa, kia kore ai e puta he ahi, he pahū rānei nā te mura pūmau, kia mau ai te haumaru o te pūnaha.

E whai pū ana te NSEN i ngā ratonga whakatika kore utu, whakakapinga kore utu me te whakahoki kore utu i roto i ngā marama 18 i muri i te whakakorenga o te takirere i ngā mahi tawhito, i ngā marama 12 rānei i muri i te tāutanga me te whakamahinga ki te paipa i muri i ngā mahi tawhito (ko tēhea te mea tuatahi). 

Mēnā ka pakaru te takirere nā te raruraru kounga i te wā e whakamahia ana i roto i te paipa i roto i te wā whakamana kounga, ka whakaratohia e NSEN he ratonga whakamana kounga kore utu. Kāore e mutu te ratonga kia ea rā anō te pakaru, kia taea ai te mahi i te takirere, kia hainatia rā anō e te kiritaki te reta whakaū.

I muri i te paunga o taua wā, ka oati a NSEN ki te whakarato i ngā ratonga hangarau kounga i te wā tika ki ngā kaiwhakamahi ina hiahiatia te whakatikatika me te tiaki i te hua.
