Hei taputapu nui mō te whakahoro me te whakaōrite, kei te piki haere te whakamahinga o ngā pūrutara. Mā ngā pūkenga whakahaere me ngā tikanga matatau ka āwhina i a tātou ki te whai wāhi pai ake ki te hanga pūrutara, me te whakatutuki i te mana rua me te haurua o te kaha. He mea tino nui ngā pūrutara i roto i te hanganga kaupapa. Hei whakarite kia kore he raruraru i te wā hanga, me āta tirotiro te mamau, te whakateretere, te pūrutara, te rakau hari, me ētahi atu i mua i te hanganga.
1. Ina piki, ina heke te puruta i te pari, kaua te pikinga e neke atu i te 30°; ina mahi ana i te pari whakawhiti, kaua te pikinga o te angaanga e neke atu i te 10°. Ina heke ana, he pai ake te hoki whakamuri me te heke iho. Kāore e whakaaetia te nekeneke i te koretake. Mena e tika ana, tukua te mata ki raro hei āwhina i te aukati.

2. Ina mahi ana i ngā pari pari me ngā pae maunga teitei, me whai kaimahi hei whakahaere, ā, kaua te mata e neke ake i te taha o te pari.
3. Ina mahi ana i roto i ngā rua poutū, kaua te hohonutanga o te rua e neke ake i te 2cm mō ngā puruta nui, me te 1.5cm mō ngā puruta iti. Kaua ngā mata o te puruta e pana i ngā kohatu nunui, i ngā poraka oneone nui rānei i runga i te pakitara pari kia teitei ake i te tinana.
4. I te tango i te mata o te bulldozer, me mahi tahi ngā kaiawhina tango i te mata me te taraiwa. I te wa e kukume ana i te taura waea, me mau karapu kānawehi. Kāore e whakaaetia te titiro tata ki te kōhao taura.

5. Mēnā he maha ngā mīhini e mahi ana i runga i te mata mahi kotahi, kaua e iti iho i te 8m te tawhiti i waenganui i ngā mīhini o mua me muri, ā, kaua e neke atu i te 1.5m te tawhiti i waenganui i ngā mīhini maui me matau. Mēnā e rua, neke atu rānei ngā puruta e puruta ana i te taha ki te taha, me 20~30cm te tawhiti i waenganui i ngā mata puruta e rua. Me tere te taraiwa i te rārangi tika i te tere kotahi i mua i te puruta; me whakarite kia kore ai e tukinga tetahi ki tetahi i te wā e hoki whakamuri ana.
6. Ina whakamahia te bulldozer hei tango i ngā pakitara pakaru, me whakapai ake ngā wāhi matua kia kore ai e taka whakamuri te taha whakamuri.
Ko ngā mātāpono hei ako māu i te wā e whakahaere ana i te bulldozer ko: te whakahaere i te bulldozer taputapu tuatahi; me karo i te kawenga kotahi i ngā wā katoa e taea ana, me pupuri tonu te kaha o te bulldozer kia pumau, me te whakaiti i te tawhiti o ngā waka kau. Ko tāku tumanako ka āwhina i a koe ngā kōrero o runga ake nei.
