Sinikezela ngezinto ezihamba phambili zebhandeshi lehhashi: ibhande lokubhinca elihlanganayo lehhashi, ikhwalithi ingaqhathaniswa nebhandeshi elifanayo lamahhashi elenziwe yi-3M, lokhu okuhlinzekwa ngebhandeshi lamahhashi kufanelekile ekugijimeni kwamahhashi, ngoba ukubambelela okuhlanganayo kunamandla, futhi izinto ezingavukiwe zinobungane ehhashini.

Futhi izimpahla zebhandeshi zamahhashi zisetshenziselwa ukwelashwa kwamahhashi, ukuklanywa ngokukhethekile nokusetshenziselwa ihhashi.
