Mu gihe co gutera irangi, umuyaga wo hanze uracungururwa biciye ku kiyunguruzo ca mbere hanyuma ukaja ku gisenge biciye ku gikoresho co gupfuka umuyaga. Inyuma y’ugucungera ubwa kabiri no gusukurwa n’icunguru co hejuru, ryinjira mu rusengero. Umuyaga uri imbere mu ngoro ugenda umanuka ku muvuduko urenga canke ungana na 0,3 m/s, ugatuma utugingo ngengabuzima tw’umugabo w’irangi tudashobora kuguma mu kirere kandi tukareka tuca mu kayunguruzo ko hasi ataco duhinduye imbere y’uko turuha hanze biciye mu nzira y’isohoka. Ukwo gukomeza gucapura bituma ubusuku bw’umuyaga uri mu nzu y’irangi bushika ku bice birenga 98% mu gihe co gutera irangi, kandi umuyaga utangwa ugira umukazo kanaka wo kubuza inkungugu kwinjira mu nzu y’irangi no kwanduza ahantu h’igikoresho, gutyo bikaba bituma igikorwa co gutera irangi kiba ciza cane.
Mu gihe co guteka, iyo damper irahindurwa kugira ngo igere ku kibanza co gutekeramwo, maze umuyaga ushyushe urazunguruka, ugatuma ubushuhe bwo mu nzu yo gutekeramwo bushika ku bushuhe bwategekanijwe bwo kwuma ( Buri munsi canke bungana na degre 80 ). Ico gikoresho gica gicungera umuyaga mwiza wo hanze, hanyuma kigaca gihindura ubushuhe n’ico gikoresho gihindura ubushuhe imbere y’uko kija mu cumba c’umuyaga kiri hejuru y’aho bateka imikate. Inyuma y’ugucungera no gusukura ubwa kabiri, uwo muyaga ushyushe, biciye mu nzira y’imbere mu gipfukisho, ahanini urasubira gushushwa ugasubira gukoreshwa, kiretse umuyaga mwiza mutoyi, ivyo bikaba bituma ubushuhe buri mu nzu yo gutekeramwo imikate bugenda buragwira buhorobuhoro. Iyo ubushuhe bushitse ku bushuhe bwategekanijwe, umuriro urahagarara ubwawo; iyo ubushuhe bugabanutse bukaja ku bushuhe bwashinzwe, umuyaga n’igikoresho co gucana birasubira gucana kugira ngo ubushuhe bube budahinduka imbere mu nzu y’irangi. Ubwa nyuma, igihe co guteka irangi kigeze ku gihe cashinzwe, iyo nzu y’irangi iraheza igafunga, maze igikorwa co guteka irangi kiraheza.
