I-1, ifanele ibe lula kwaye igudileyo, ingabikho ukuqhekeka, imiphetho ebukhali kwaye itshiswe kunye nezinye iziphene, ukusetyenziswa kweglasi yokukhulisa kunye nezinye iindawo kunokuphononongwa.

I-2, i-shackle yokuphinda kabini umthwalo wokhuseleko njengomthwalo wokuvavanya ukuvavanya. Iphini ye-shaft kufuneka ingakhubazeki ngokusisigxina kwaye ikhululeke ukujikeleza emva kokukhulula. Ubude bobude bomzimba abuyi kudlula i-O.25% okanye i-O.5mm. Iitoni ze-300 ezi zihlandlo ezi-2 zilandelayo zokhuseleko njengomthwalo wokuvavanya ukuvavanya, ngaphezu kweetoni ze-300 ze-1.33 amaxesha okhuseleko njengomthwalo wokuvavanya ukuvavanya.

I-3, i-shackle ingaba uvavanyo lokuthembeka kwesampulu. Umthwalo uphindwe kabini umthwalo wokuvavanya. Ikhama aliyi kwaphulwa okanye ityathanga lonakale.

I-4, ukusetyenziswa kwe-shackle yomthwalo wokhuseleko yi-M (4) evunyiweyo.

I-5, kumzimba weqhosha kufuneka imakishwe ngenqanaba lamandla, umthwalo wokhuseleko kunye nezinye iimpawu.
