Izindlela zokushayela ezingafanele ziyisici esiyinhloko esidala umonakalo kuamathrekhi enjoloba. Ngakho-ke, ukuze kuvikelwe amathrekhi enjoloba futhi kunwetshwe impilo yabo yesevisi, abasebenzisi kufanele banake lezi zinyathelo zokuphepha ezilandelayo lapho besebenzisa umshini:

(1) Ukuhamba ngokugcwala ngokweqile akuvunyelwe. Ukuhamba ngokweqile kuzonyusa ukungezwani kwe-amathrekhi okulayisha ithrekhi ahlangene, isheshise ukuguga kwensimbi ewumgogodla, futhi ezimweni ezimbi kakhulu, yenza ukuba insimbi ewumgogodla iphuke futhi intambo yensimbi inqamuke.

(2) Ungashintshi ngokucijile lapho uhamba. Ukujika okucijile kungabangela kalula ukuhlukana kwamasondo kanye nokulimala kwethrekhi, futhi kungabangela isondo eliqondisayo noma umzila wesitimela we-anti detachment ushayisane ne-core iron, kubangele ukuba i-ayoni ewumgogodla iwe.

(3) Akuvunyelwe ukukhuphuka izitebhisi ngenkani, njengoba lokhu kungase kubangele imifantu empandeni yephethini futhi ezimweni ezinzima, kubangele ukuphuka kwentambo yensimbi.

(4) Akuvunyelwe ukuhlikihla nokuhamba onqenqemeni lwesinyathelo, ngaphandle kwalokho kungase kubangele ukuphazamiseka emzimbeni ngemva kokuba unqenqema lwethrekhi lugudluke, okubangela imihuzuko kanye nokusikeka onqenqemeni lwethrekhi.

(5) Vimbela ukuhamba kwebhuloho, okungesinye sezizathu eziyinhloko zokulimala kwephethini nokuphuka kwensimbi ewumongo.

(6) Akuvunyelwe ukuncika nokuhamba emithambekeni (Umdwebo 10), njengoba lokhu kungase kubangele ukulimala kwamasondo ethrekhi ngenxa yokuhlukaniswa.

(7) Njalo hlola isimo sokuguga sesondo lokushayela, isondo lokuqondisa, nesondo lokusekela. Amasondo okushayela aguge kakhulu angakwazi ukuxhuma i-ayoni ewumgogodla futhi abangele ukuguga okungavamile kwe-ayoni ewumongo. Amasondo anjalo okushayela kufanele ashintshwe ngokushesha.

(8) Amathrekhi enjoloba kufanele agcinwe futhi ahlanzwe njalo ngemva kokusetshenziswa ezindaweni ezinenhlabathi eningi kanye namakhemikhali endizayo. Uma kungenjalo, izosheshisa ukuguga nokugqwala kwe-amathrekhi enjoloba angasindi.
