1. Te Āninitanga me te Ngoikore o te Mekameka Matua
Ko te tōpana tika o te mekameka te mea tino nui pea hei tiaki. Ko te ngoikore rawa te tino take o te kino, ka taea ai e te mekameka te pupuhi, te peke i ngā porotiti, me te heke i te taura. I tetahi atu taha, ko te mekameka tino piri ka tere ake te pakaru o ngā hononga me te kino o ngā porotiti. Ko te whāinga kia mau tonu te tōpana-mua e ārai ana i te tōpana i raro i te kawenga me te kore e nui rawa te taumahatanga. Inehia me te whakatika i te tōpana i ia wā mā te whakamahi i tētahi mita tōpana kua whakatikatikaina, ā, tangohia te tōpana o te mekameka i roto i ngā wāhanga iti, kua whakahaeretia (hei tauira, e rua ngā hononga i te wā kotahi).
2. Aroturuki me te Ine i te Roroa o te Mekameka
Kāore te mekameka e "toto" pono; ka roa ake nā te pakaru o ngā hononga i ngā wāhi e pā ana. Ko te aroturuki i tēnei roa he huarahi tika ki te ine i te hauora o te mekameka me te roa o te ora. Whakamahia he caliper mekameka hei ine i te roa o te nekehanga kua whakaritea. Hei aratohu whānui, ka whakaarohia pea ngā mekameka kia whakakapia ina neke atu i te 3% te roa, ahakoa he maha ngā mahi e whakatakoto ana i te rohenga pumau ake o te 2%.
3. Whakatinanahia he Mahinga Tirotiro Pūmau
Mā ngā tirotiro ā-kanohi me ā-tinana kua whakaritea ka kitea pea ngā raruraru iti i mua i te horapa haere. Me whakauru atu ki roto i tō rārangi arowhai:
- Ngā Pīni: Tirohia mēnā he niho kua pakaru, kua marere, kua tapahia rānei. Ka tere ake te pakaru o te mekameka mēnā he pīni kua pakaru, ā, ka kore e tika te hononga.
- Te Whakaritenga: Kia tika te whakarite o ngā porotiti, ngā ipu kawe, me te rārangi mata katoa. Mēnā he iti te rārangi mata, ka kore e ōrite te taumahatanga me te rerekētanga o te pakaru i waenga i ngā miro mekameka.
- Ngā Hononga me te Hanganga: Whakakīia ngā nati hononga me ngā here here katoa e wetekina ana, ā, whakakapia ngā pūtu hono-paraoa e ngaro ana. Tirohia mēnā he paraoa kua pakaru, he rīpene pakaru rānei e taea ai te arahi hē i te mekameka.
4. Whakatinanahia he Kaupapahere Whakakapinga Matatau
Kaua e whakahaere i ngā wāhanga kia pakaru. Whakatūria he paearu mārama, e ahu mai ana i ngā raraunga mō te whakakapi i ngā takirua mekameka me ngā pītiti i runga i ngā inenga roa me te pakaru o te pītiti. Ko te whakahaere i te mekameka kua pakaru rawa me ngā pītiti hou (tērā rānei) ka tere te pakaru o ngā mea e rua.
