Umwihariko wa bombi-umugozihamwe na kare kare ni uko ihuza ibyiza byinshi byo gushushanya. Mbere ya byose, igitekerezo cyaSEMS, ifite ibikoresho bya kwaduka kare kuri screw, ni igishushanyo gishya kidatanga gusa umutekano wizewe, ariko kandi kigabanya cyane umuvuduko wumutwe wa screw hejuru yibikoresho mugihe cyo kwishyiriraho, bityo bikagabanya ibyago byo kwangirika .

Icya kabiri, ibirangaimigozi yabigeneweemerera abakoresha guhitamo ingano ikwiye nibisobanuro ukurikije ibyo bakeneye byihariye. Niba diameter ntosqare washerzirakenewe, cyangwa uburebure bwurudodo rurerure, turashoboye guhuza ibicuruzwa byacu kugirango duhuze ibyifuzo byabakoresha batandukanye.

Hanyuma ,.imigozi ibiri yo guhuzahamwe na kwaduka ya kare ihuza guhuza no guhinduka kwaimigozi hamwe na kare. Irakwiriye kubikoresho byinshi, birimo ibyuma, ibiti, na plastiki, kandi birashobora gukoreshwa muburyo butandukanye bwo guterana no gutunganya ibintu.
