Umshini uklanyelwe ngokukhethekile igumbi lomthamo wesibhedlela, isikhungo selabhorethri, umkhiqizo wokunakekelwa kwezempilo, imboni yekhemisi ephakathi nendawo encane futhi evezwe ngumzimba womshini ohlangene, ukusebenza okulula, imisebenzi eminingi, ukulungisa unhlangothi. Ifanele iphakheji ye-ALU-ALU ne-ALU-PVC yemithi, ukudla, izingxenye zikagesi njll.
Umshini okhethekile wohlobo lwethrekhi lwesisekelo somshini wokuphonsa, othathe inqubo yomlilo ongemuva, ukuvuthwa, ukwenza isisekelo somshini ngaphandle kokuhlanekezela.
