Lapho usebenzisa izitshalo zokuxuba i-asphalt, imithethonqubo ihlanganisa izinto okufanele zenziwe nezinto ezingavunyelwe. Kungakhathaliseki ukuthi yisiphi isici esihlobene kakhulu nomphumela wokusetshenziswa kwesisetshenziswa. Umhleli ubhale ezinye izinto ezingavunyelwe esitshalweni sokuxuba itiyela, zigcine nje engqondweni.
Ngesikhathi sokusetshenziswa kwezitshalo zokuxuba i-asphalt, opharetha banqatshelwe ukuqala i-impeller yokuxuba lapho ingcwatshwa endabeni eqinile ukugwema umonakalo ku-impeller; ngesikhathi esifanayo, ukungqubuzana nokushaywa kwe-counter-axis kokuhlangana kwemishini akuvunyelwe; ngokuvamile, imishini yokuxuba i-asphalt Akuvunyelwe ukoma futhi kufanele ihlolwe ngaphambi kokwengeza izinto.
Okunye okungafanele sikukhohlwe ukuthi asikwazi ukushintsha isingeniso sokuxuba emishinini. Kufanele ihlangabezane nezidingo zokuklama, ngaphandle kwalokho umphumela wokusetshenziswa olindelekile ngeke ufezwe.
