Umshini wezitini ongashile udlidliza ngamandla, okuvame ukuba nezingozi ezifana nokuxegiswa kwezikulufu, ukuwisa izando okungavamile, njll., okuholela ezingozini zokuphepha. Ukuqinisekisa ukuphepha, naka amaphuzu amathathu alandelayo lapho usebenzisa umshini wokucindezela izitini ngendlela efanele:

(1) Naka isondlo. Umthwalo wokusebenza kanye namahora okusebenza emishini yezitini engashisiwe iyafana neyeminye imishini, okuncike ekusebenzeni okuvamile nokugcinwa kwezingxenye eziyinhloko. Kufanele silinde njalo ukuhlola imishini yomshini wokunyathelisa ngezitini. Ukuze uthole imishini emisha yezitini, umshini wokucindezela izitini ezinemibala kanye nomshini wokunyathelisa wezitini we-hydraulic, qaphela ukuhlola ukuminyana. Kungase kube nezinkinga eziningi ezincane lapho ziqala ukusetshenziswa, ngakho ungabi budedengu. Ngemuva kokusebenzisa isikhathi esithile, inani lokuhlola lingancishiswa ngokufanelekile, kodwa ukuhlolwa okuvamile kuyadingeka. Imishini enezinga eliphezulu lokusebenza kufanele ihlolwe njalo.

(2) ukuze kuqinisekiswe ukusetshenziswa okujwayelekile kwemishini futhi ungalibali isikhathi sokwakha, khumbuza amabhizinisi ukuthi ngaso sonke isikhathi agcine izinsimbi eziyisipele ezingagugi lapho esetshenziswa endaweni yokugcina impahla.

Izingxenye ezivame ukulimala ngokuvamile ziyizindawo ezinomthwalo osindayo. Ngesikhathi sokusetshenziswa, ama-opharetha kufanele abhekwe ngokucophelela futhi okungavamile kufanele kutholakale ngesikhathi ukuze kuqinisekiswe ukusebenza okuphephile.

(3) Ngaphambi kokusebenzisa umshini wezitini ongashisiwe, kufanele ubhekwe ngokucophelela ngaphambi kokusetshenziswa. Akuvumelekile kwabangewona ochwepheshe ukusebenzisa imishini. Naka ukulandelana kokusebenza futhi ungashintshi inqubo yokusebenza.
