Ihame ryakazi rya comptabilite yuburyo bubiri nuburyo bukurikira: moteri mumashanyarazi iringaniza itwara eccentric kugirango itange ibinyeganyega binyuze muri clutch na pulley, hanyuma isahani yo hepfo na eccentric bishyizwe hamwe. Guhindura icyerekezo cyo kunyeganyega, birashobora kugerwaho muguhinduranya eccentric. Ikigeretse kuri ibyo, kugirango ugere kunyeganyega imbere, mu kunyeganyega, hamwe no kunyeganyega inyuma.
