Ka whakawhirinaki te keri toka waewae-hau ki te hau kōpeke hei akiaki i te piston kia hoki whakamuri. I te wā e whiua ana, ka pā te piston ki te hiku o te kakau, ā, i te wā e whiua ana, ka hurihia te taputapu keri e te piston kia tutuki ai te kuru me te keri toka. Ko te whakamahinga o ngā taputapu keri waipēhi katoa hei whakakapi i ngā keri toka waewae-hau he ia e kore e taea te karo i roto i te whanaketanga o te keri toka waro. Heoi, i tēnei wā, neke atu i te 90% o ngā kauhanga toka e whakahaerehia ana e te keri toka waewae-hau. Ko te keri toka waewae-hau he hua ringaringa-ringa, he taputapu neke-ā-ringa (he taputapu neke ā-ringa, he taputapu whakahaere-ā-ringa) he nui te rahinga me te whānuitanga o te whānuitanga. He watea te whakahaere me te tiaki, ā, he iti te utu.
