Ukubekezelelana okungaphandle kokujikeleza kusebenza kumadayamitha aphezulu naphansi njengoba kulinganiswa nge-bar gauge, i-caliper, noma idivayisi elinganisa amadayamitha angempela aphezulu naphansi.
Ububanzi obumaphakathi (njengoba bulinganiswa ngetheyipu yobubanzi) bokuphela kwepayipi elilodwa akumele buhluke ngaphezu kwamasentimitha angu-2.38 (3/32 in.) kobo komunye umkhawulo.

Amanothi:
1. Ukubekezelelana kwesisindo kusebenza ezisindweni ezibalwe zepayipi elinezintambo nezihlanganisiwe kanye nasezisindweni ezibalwe etafuleni noma ezibalwe zepayipi elingenasici. Lapho ukubekezelelana kobukhulu bodonga obungebuhle obuncane kunalezo ezibalwe etafuleni elingenhla kuchazwe ngumthengi, ukubekezelelana kwesisindo okuhlanganisiwe kobude obubodwa kuzokhushulwa kube ngamaphesenti angama-22.5 kuncishiswe ukubekezelelana kobukhulu obungebuhle.
2. Emithwalweni yemoto eyakhiwe ngamapayipi avela ezintweni ezingaphezu kweyodwa ze-oda, ukubekezelelana kwemithwalo yemoto kufanele kusetshenziswe ngokwesisekelo sento ye-oda ngayinye.
3. Ukubekezelelana kwezinto ze-oda kusebenza enanini eliphelele lepayipi elithunyelwe lento ye-oda.
