Ngā wiri toka YT27 i mua i te whakamahinga: He aha te wiri toka hau?

2, Patohia te tuanui e tata ana ki te mata mahi, arā, tirohia mēnā he kōhatu ora me he kōhatu koretake kei runga i te tuanui, me te tuarua o ngā kōhatu e tata ana ki te mata mahi, ka mahi i te maimoatanga e tika ana.

3, me patupatu te mata mahi o te wāhi papatahi o te kōhao anga, kia papatahi i mua i te tuku i te keri toka, hei ārai i te paheke, te neke rānei o te kōhao anga.

4. Kāore rawa e whakaaetia te keri i ngā kanohi maroke, ā, me tohe tonu tātou ki te keri i te toka mākū, me tahuri te wai i te tuatahi, kātahi ka tahuri te hau i te wā e mahi ana, ā, me whakaweto te hau, kātahi ka tahuri te wai i te wā e mutu ana te keri. I te whakatuwheratanga o te poka, me oma i te tere puhoi i te tuatahi, kātahi ka keri i te tere katoa i muri i te keri ki tētahi hohonutanga.

5, Kāore e whakaaetia kia mau karapu ngā kaiwero i te wā e keri ana.

6, Ina whakamahia te waewae hau hei keri i te kōhao, kia tupato ki te tūnga me te tūranga o te tūnga, kaua rawa e whakawhirinaki ki te tinana hei pēhanga, kaua rawa e tū ki mua i te keri toka i raro i te tokotoko whakakoi mahi, hei ārai i te whara mai i te pakaru o te whakakoi.

7, Ki te kitea he haruru rerekē me te rerenga wai rerekē i roto i te keri toka, kati te mīhini kia tirohia, kimihia te take, ā, whakakorea i mua i te haere tonu ki te keri.

8, Ina tangohia mai i te wiri toka, ina whakakapia rānei te tokotoko whakakoi, ka taea e te wiri toka te oma puhoi me te aro ki te tūranga o te whakakoi wiri toka.
