• Ubujyakuzimu bw'icyuma hejuru cyangwa munsi y'ibikoresho bigomba gutemwa ntibigomba kurenza 1/4 ".Igenamiterere ritera ubushyamirane buke, bigatuma ubushyuhe bwiyongera kandi butanga imbaraga nke mugihe usunika ibintu. Muri rusange imyumvire itari yo nuko igenamigambi ryimbitse rizatanga ibyiza kandi bikomeye.

• Ntuzigere uhatira icyuma icyo ari cyo cyose guca vuba kurenza uko cyateganijwe.Iyo ukoresheje ameza afite imbaraga nkeya cyangwa ibizunguruka, umva moteri. Niba moteri yunvikana nkaho “igenda hasi,” noneho gahoro gahoro. Ibiti byose byateguwe gukata kuri RPM runaka kandi bigakora neza kuri iyo RPM.

• Hamwe nameza yose yabonye icyuma, ibuka ko amenyo hejuru yubuso bwameza azenguruka mu cyerekezo cyumukoreshahanyuma winjire hejuru yubuso bwakazi mbere; rero, shyira inkwi kuruhande rwuzuye hejuru. Ibi byaba binyuranye mugihe ukoresheje ukuboko kwa radiyo cyangwa uruziga. Ibi bireba pani isanzwe, veneers, nuburyo ubwo aribwo bwose bwa pande hamwe na laminate ifatanye. Iyo impande zombi zinkwi zirangiye, koresha icyuma cyinyo cyinyo gifite byibuze cyashizweho cyangwa icyuma cyubutaka. 

• Icyuma cyijimye cyangwa cyangiritse gitera akaga.Buri gihe ugenzure ibyuma byawe ku nenge iyo ari yo yose nko kubura inama z'amenyo, kubaka ibisigazwa no kurigata.

 
Gukora ibiti nakazi keza cyangwa kwishimisha, ariko abantu barenga 60.000 barakomereka bikabije bakoresheje ibiti byameza buri mwaka. Wibuke ko kumenyera bibyara agasuzuguro. Iyo umuntu akoresheje ibiti, bakunda kwigirira icyizere, aribwo impanuka zishobora kubaho. Ntuzigere ukuraho ibikoresho byose byumutekano mubiti byawe. Buri gihe ukoreshe kurinda amaso, ikibaho cyamababa, fata ibikoresho hanyuma usunike inkoni neza.
 
Imwe mumpamvu zitera impanuka zituruka kumeza adahagije kandi yameza cyangwa ibiryo. Igisubizo gisanzwe nugufata ikibaho cyangwa ikibaho iyo kiguye kandi mubisanzwe byaba byiza hejuru yicyuma. Kora neza kandi ukore ubwenge kandi uzagira imyaka myinshi yo kwishimira ibiti.
