Me pakari, me tino tika hoki te whakapūmau, he mea tika tēnā. Ina hoki, he mea pai kia kaua e tūtaki ki ēnei āhuatanga ina whakamahia ngā whakapūmau:
1: Ngā kapiti e piri ana.
2: I te wā e whakakīia ana te rivet, ka piko te tokotoko rivet, ā, kāore e taea te whakakī.
3: He mārō rawa te rauemi o te rivetkia neke ai te riu hurihuri.
4: He ngohengohe rawa te rauemi o te rivet, ā, kua rerekē te āhua o te flange me te taha rivet, kāore e ātaahua.
Ko te hangarau haumaru o te whakapūmau i ngā hononga ko ngā āhuatanga e whai ake nei:
1. I mua i te whakakī,me tirotirohia te pū me te kakau o rungakia kore ai he kapiti, he koriri rānei.
2. Me mau tonu te pū whana ki te pū rivet ina tāutahia; i muri i te tāutanga o te whana, kaua te pū rivet e anga atu ki te tangata kia kore ai e pā kino ki te pū, ā, ka puta he aituā. I muri i te otinga o te whana, me tango tonu te whana.
3. I te wā e whakakī ana i ngā riu, me mau ngā ārai taringa, ngā ārai taringa rānei te kaipū matua me te kaipū o runga hei whakaiti i te haruru e pā ana ki ngā taringa.
4. Me mau potae tiaki ngā kaimahi e mahi ana i raro i te arawhata o te whare teitei me te arawhata mahi ina hiahiatia, hei ārai i ngā taonga teitei kei hinga, kei whara rānei te tangata; ina patupatua ana ngā patu me ngā patu ki te hama, me ārai i ngā maihao kei whara. Me huri wawe ngā pūwero o ngā patu me ngā patu i runga i te hurihanga pae kia kore ai e whara te tangata i te hinganga o ngā pūwero i te patupatua.
