1. Isisekelo senqwaba singasetshenziswa lapho isisekelo sibuthakathaka futhi isisekelo semvelo singakwazi ukuhlangabezana nezidingo zamandla esisekelo kanye nokuguqulwa kwaso.
2, uma kunezidingo eziqinile zokuguqulwa kwesakhiwo, kufanele kusetshenziswe isisekelo senqwaba.
3. Isisekelo sezinqwaba kufanele sisetshenziswe lapho izakhiwo noma izakhiwo eziphakeme zinezidingo ezikhethekile zokunciphisa ukuthambekela.
4. Isisekelo senqwaba kufanele sisetshenziswe lapho isisekelo sendawo sinethonya elihlangene ezakhiweni eziseduze.
5, isitshalo sezimboni esinzima esinesitezi esisodwa esine-crane enkulu enamathani amakhulu, umthwalo we-crane mkhulu, usetshenziswa njalo, ipulatifomu yemishini yokusebenzela, isisekelo esiminyene, futhi ngokuvamile sinomthwalo womhlabathi, ngakho-ke ukuguqulwa kwesisekelo sikhulu, bese isisekelo senqwaba singasetshenziswa.
6, isisekelo semishini enembile kanye nesisekelo semishini yamandla, ngenxa yokuguquguquka kanye nokuphakama okuvunyelwe kunezidingo eziphakeme, ngokuvamile kusetshenziswa nesisekelo senqwaba.
7, indawo yokuzamazama komhlaba, esisekelweni esingancibilika, ukusetshenziswa kwesisekelo sezinqwaba ngokusebenzisa ungqimba lomhlabathi olungancibilika futhi kudlulele ongqimbeni lomhlabathi oluqinile oluphansi, kungasusa noma kunciphise umonakalo wokuncibilika kwesakhiwo.
