I-YT27umshini wokubhoboza idwala osebenzisa umoyaizuze idumela lokuqina nokuthembeka. Yakhelweukumbiwa kwezinga eliphakathikanye nokumba, ilinganisela ukusebenza kalula nokugcinwa kwayo. Isando sayo somoya esiqhutshwa yi-piston sinikeza ukusebenza kahle kokubhoboza okuzinzile ngisho nangaphansi kokusebenza okuqhubekayo.
Abaqhubi bayazuza ngomklamo wayo olula, okwenza ukulungiswa kusheshe futhi kunciphisa isikhathi sokungasebenzi. Ilungele ukubhoboza okuthambekele nokuqondile,YT27iyaqhubeka nokusebenza njengokukhetha okuthembekile kwabavukuzi abathuthukisa imishini yokuzilolonga emidala noma ukuqala amaphrojekthi amasha.
