Ukuvikelwa kokugqwala kwemikhiqizo yensimbi
Ulayini wokulungisa ngaphambilini uhlanganisa ukushisa kwangaphambili, ukuqhunyiswa kwesibhamu, ukupenda nokomiswa kwezingcezu zokusebenza (njengamapuleti ensimbi namaphrofayela) emugqeni owodwa wokukhiqiza ozenzakalelayo.
Imigqa yokwelapha kusengaphambili ilungile uma kunezikhathi ezinde zokukhiqiza noma zokugcina phakathi kokuqhunyiswa nokunamathiswa.Ukuze uvimbele ukugqwala kabusha, ukufafaza okufika ngesikhathi kwe-primer kungaqinisekisa ukumelana nokugqwala amasonto ambalwa.
Ububanzi bepuleti bungafinyelela ku-5500mm, futhi isivinini sokudlulisa setafula le-roller sisuka ku-1.0-6.0 m/min.
