1. Umsebenzi ongundoqo omnye, ukhuselekile kwaye uthembekile, iqondo eliphezulu lobukrelekrele, elilungele i-Elevator yazo zonke iimbewu ze-oyile ngaphandle kwembewu yodlwengulo.
2. Imbewu yeoli iphakanyiswa ngokuzenzekelayo, ngokukhawuleza ngokukhawuleza.Xa i-hopper yomatshini we-oyile igcwele, iyakumisa ngokuzenzekelayo izinto zokuphakamisa, kwaye iya kuqalisa ngokuzenzekelayo xa imbewu yeoli ingonelanga.
3. Xa kungekho nto iya kuphakanyiswa ngexesha lenkqubo yokunyuka, i-alamu ye-buzzer iya kukhutshwa ngokuzenzekelayo, ebonisa ukuba ioli iyazaliswa.
