Ibiranga umwihariko udasanzwe ushobora guhindurwa inyuma yemerera abakoresha guhitamo urwego rwimikorere ijyanye neza nibyifuzo byabo kugiti cyabo bahindura imyanya y'intoki itambitse mubitugu. Iyi mikorere idasanzwe, ihujwe no guhuriza hamwe ukuboko kwingingo imwe kuri dogere 20 hejuru no imbere yumukoresha hamwe nuburyo bubiri, itanga uburyo bwuzuye bwimyitozo yimikorere nta ngaruka.
Intebe irashobora guhindurwa wicaye cyangwa uhagaze, kandi ifashwa nu murongo wo mu rwego rwohejuru utondekanya umurongo hamwe na silinderi kugirango uhindurwe neza, uduce duto duto.
Intwaro yo kwikuramo uruhande rumwe ihuza dogere 20 kuri buri ruhande hejuru no imbere yigitugu, bigatuma urwego rwuzuye rutagira ingaruka.
