1.Ibikoresho bimeze neza, urufunguzo nyamukuru ntiruhindura, nta gusimbuka kurasa, kwishyiriraho birakomeye, kandi nta kunyeganyega.

2.Reba niba icyuma cyangiritse cyangiritse, niba imiterere y amenyo yuzuye, niba icyuma kibonye cyoroshye kandi gifite isuku, kandi niba hari ibindi bintu bidasanzwe kugirango ukoreshe neza.

3.Iyo guteranya, menya neza ko icyerekezo cy'imyambi y'icyuma kibonye gihuye n'icyerekezo cyo kuzunguruka cy'igiti kinini cy'ibikoresho.

4.Iyo ushyiraho icyuma kibisi, komeza hagati ya shaft, chuck na flange. Diameter y'imbere ya flange ni kimwe na diameter y'imbere y'icyuma kibonye. Menya neza ko flange hamwe nicyuma kibisi byahujwe cyane, shyiramo pin ihagaze, hanyuma ushimangire ibinyomoro. Ingano ya flange igomba

bikwiye, kandi diameter yo hanze ntigomba kuba munsi ya 1/3 cya diametre yicyuma.

5.Mbere yo gutangira ibikoresho, muburyo bwo kurinda umutekano, hariho umuntu umwe wo gukoresha ibikoresho, kudakora kwiruka, kugenzura niba kuyobora ibikoresho ari byo, niba hari kunyeganyega, kandi icyuma kibonye kigomba gukora muminota mike nyuma yo gushyirwaho, kandi bizakora mubisanzwe nyuma yo kutanyerera, kuzunguruka cyangwa gusimbuka.
