Amanqaku:
1. Ukunyamezela ubunzima kusebenza kwiisisindo ezibaliweyo zepayipi edibene ngemisonto kunye nobunzima obudweliswe okanye obubaliweyo bepayipi engenanto. Apho ukunyamezela ubukhulu bodonga obungaphantsi kobo budweliswe kwitheyibhile engentla kuchazwe ngumthengi, ukunyamezela ubunzima obungaphezulu kobude obunye kuya kwandiswa ukuya kwi-22.5 ekhulwini ngaphantsi kokunyamezelana okungaphantsi kobunzima be-wail.
2. Kwimithwalo yemoto eyenziwe ngepayipi evela kwizinto ezingaphezu kwesinye zeodolo, ukunyamezelana kwemithwalo yemoto kufuneka kusetyenziswe ngokwesiseko sento nganye yeodolo.
3. Ukunyamezelana kwezinto ze-odolo kusebenza kubungakanani obupheleleyo bombhobho othunyelweyo wento ye-odolo.
