1. Imikorere ibiri: imikorere ya bartack, hamwe na gahunda yo kudoda gahunda yo kudoda hamwe nubunini bunini 60mm * 60mm. Kandi ituma imashini ishobora kudoda ubwoko bwinshi bwuburyo bugoye. Ongeramo ubwoko 1000 bwuburyo bwo guterana: igice cyakwezi cyakurikiranye, gutondekanya kuzengurutse hamwe na chrysanthemum-imeze-umwobo wo gutobora, kaseti ya elastike idahuzagurika, guhuza ibirango, ikarita yerekana ikarita yerekana ibicuruzwa nibindi byashize.
2. Guhanga ukoresheje igikoresho cyo hagati cyo gukanda ibirenge kugirango ukore neza kubunini bunini bwo gutondeka umurongo kandi biroroshye kudoda ibintu bigoye.
3. Imashini ifite ubwoko bubiri: imwe iri hamwe nikintu cyo kugaburira imashini gikwiranye nibikoresho byoroheje, ikindi kiri hamwe na silindiri ebyiri itwara ikariso yo kugaburira ibereye ibintu biremereye.
4. Imashini ni imashini yubwoko bwumuvandimwe, ikwiranye nibikoresho byinshi.
5. Birakwiriye gukandagira neza ibirenge kandi hari imikorere myiza yikirenge gikurikira. Urusaku rw'ikirenge gikanda rugabanutse cyane kubikorwa byiza.
