2) Kuzungulira kwa kubowolako pobowola pozungulira, kuzungulira kwa koloko mozungulira kozungulira kwa chikhatho cha dzino kumatchedwa auto rotation. Kuthamanga kwa kasinthasintha kwa chulucho kumatsimikiziridwa ndi liwiro la kusintha kwa kubowola, ndipo kumagwirizana ndi zotsatira za mano pansi pa chitsime.
3) Kugwedezeka kwautali (kugwedezeka kwa axial) kuphwanya kwapang'onopang'ono pobowola Kusintha kwa malo apakati pa gudumu kumapangitsa kuti chobowolacho chibwezere mmwamba ndi pansi motsatira njira ya axial, yomwe ndi kugwedezeka kwautali kwa bowolo, komwe kumakhudzana ndi Kubowola pang'ono kapangidwe magawo monga kutalika kwa dzino ndi katalikirana mano ndi lithology. Magawo ofewa amakhala ndi matalikidwe ang'onoang'ono, pomwe olimba amakhala ndi matalikidwe akulu. Kuthamanga kwafupipafupi kumayenderana ndi chiwerengero cha mano ndi liwiro la cone.
zimatsimikiziridwa ndi magawo structural wa kubowola pang'ono. M'mapangidwe ofewa, kutsetsereka pang'ono kumakhala kwakukulu, ndipo m'mapangidwe olimba, iwo
ziyenera kukhala zazing'ono momwe zingathere kapena zosaterera.
