Isikhathi eside,Umshini wokupakisha we-Granuleingasindisa ngempumelelo izindleko zabasebenzi kanye nezindleko zesikhathi, futhi yenze ukuthutha nokugcinwa kwezimpahla kube lula. Ngaphezu kwalokho, imishini yokupakisha ukudla isebenzisa ubuchwepheshe obuphezulu ukwenza imininingwane yomkhiqizo iphephe. Namuhla,imishini yokupakisha enemisebenzi eminingizisetshenziswa kakhulu embonini, ezolimo, ezempi, ucwaningo lwesayensi, ezokuthutha, ezentengiselwano, nokunakekelwa kwezokwelapha. Nokho, izinto zokuhlola okuvamile ngaphambi kokusebenzisa umshini wokupakisha nazo zibaluleke kakhulu.

Ukuhlolwa okujwayelekile ngaphambi kokuyisebenzisaumshini wokupakisha ukudla: Ngaphambi kokuqala umshini, udinga ukuqinisekisa ukuthi i-chassis yomshini iphansi. Qinisekisa ukuthi umfutho womoya emshinini wokupakisha uphakathi kuka-0.05~0.07Mpa. Hlola ukuthi injini ngayinye, ibhithi, njll. idinga ukugcotshwa yini. Ukusebenza okungenawo uwoyela kwenqatshelwe ngokuphelele. Umshini ungaqalwa kuphela ngemva kokujwayelekile. Ngesikhathi esifanayo, bheka ukuthi akhona yini amatshe ayigugu kuwo wonke amathangi okugcina nokuthi abambekile yini. Ukuthi kukhona udoti ebhandeni lokuthutha nokuthi ingabe ikhona yini imfucumfucu kuthrekhi yekhava yesitoreji. Ingabe amanzi, amandla, kanye nemithombo yomoya yezivalo zamabhodlela kuxhunyiwe? Ingabe akhona amapuleti ochungechunge lwempahla kuwo wonke amathangi okugcina? Ingabe banamathele ebhandeni lokuthutha? Ingabe ikhona imfucumfucu endaweni yokugcina ithrekhi? Ingabe akhona amakepisi amabhodlela? Ingabe amanzi, amandla, nomoya kuxhunyiwe? Hlola ukuthi izixhumi zengxenye ngayinye azikhululekile yini. Kuphela ngemva kokuba ukusebenza kwengxenye ngayinye kuzinzile kungasetshenziswa ngokujwayelekile.

Ngaphezu kwalezi zici ezingenhla zokuhlolwa okujwayelekile ngaphambi kokusetshenziswaumshini wokupakisha, ngesikhathi sokusebenza, u-opharetha kufanele anake ukuthi injini yomshini wokupakisha ukudla yenza umsindo noma isebenza ngokuvilapha. Uma kunjalo, yeka ukusebenza bese uqala ukuxazulula inkinga.
