Me tata ki te 800mm te tawhiti o te mekameka o te porotiti mai i te whenua. Me whakatakoto he matau porotiti hei whakairi i te pito o raro o te mekameka ki runga i te pakitara, i te pou tata rānei, kia kore ai e pā ki te ara.

2.6 Mō ngā takirere kua whakatakotoria ki roto i te awaawa, ina taea te whakatuwhera i te taupoki awaawa hei mahi, kaua te wira ringa o te takirere e iti iho i te 300mm i raro i te taupoki awaawa. Ina iti iho i te 300mm, me whakatakoto he tokotoko toronga takirere kia noho tōna wira ringa ki roto i te 100mm i raro i te taupoki awaawa.

2.7 Mō ngā takirere kua whakatakotoria ki te awaawa, ina hiahiatia kia whakahaerehia ki te whenua, mō ngā takirere rānei kua tāutahia ki raro i te papa o runga (pūhara),ka taea te whakatakoto i te tokotoko toronga takirerekia toro atu ki te taupoki awaawa, te papa, te tūāpapa mō te mahi. Me 1200mm te tawhiti o te wira ringa o te tokotoko toronga mai i te mata mahi. Kaua ngā takirere he iti iho i te DN40 te whānui ingoa, me ngā hononga miro rānei e whakamahia mā te whakamahi i ngā pīkoki, i ngā tokotoko toronga rānei hei karo i te kino o te takirere. I te nuinga o te wā, me whakaiti te whakamahinga o ngā pīkoki, ngā tokotoko toronga rānei hei whakahaere i ngā takirere.

2.8 Kaua te tawhiti i waenganui i te wira ringaringa o te takirere e karapoti ana i te tūāpapa me te taha o te tūāpapa e neke atu i te 450mm. Ina toro atu te kakau takirere me te wira ringaringa ki te taha o runga o te tūāpapa, ā, he iti iho i te 2000mm te teitei, kaua e pā ki te mahi me te haerenga o te kaiwhakahaere kia kore ai e whara.
