(1) Kuzunguruka hamwe n'ibisabwa urusaku ruke

Mu bikoresho bisanzwe byakorewe mu Bushinwa, bimwe mu biti bifata imipira ya radiyo imwe hamwe na silindrike ngufi ifite ubwoko bw’urusaku ruke rukoreshwa mu gutwara amashanyarazi.Muri byo, hari ubwoko butandukanye bwimipira kuva kumurambararo wimbere .52.5mm kugeza kuri 60mm hamwe ninyongera eshatu Zl, Z2 na Z3, zihuye nibisabwa bitatu bitandukanye byurusaku ruke.Ubwoko umunani bwibikoresho bya roller kuva N309 kugeza N322 nabyo birahari.Ubwoko butandukanye bwakozwe ukurikije urusaku ruke.

Ibi bikoresho birashobora gukoreshwa mubindi mashini zifite urusaku ruke, kandi igiciro gihenze.Niba zishobora kuzuza ibisabwa muburyo nubunini, gerageza gukoresha ubu bwoko bubiri bwurusaku ruke.

(2) Koresha ibintu bituje

Mugihe ubwoko bubiri bwavuzwe hejuru bwurusaku rudashobora gukoreshwa, ibyuma bifite urusaku ruto ugereranije birashobora gukoreshwa.Ishingiro ryihariye ryo kugereranya niryo rikurikira:

1) Urusaku rwimipira yumupira ruri munsi yurwo rufunzo rwa roller, kandi urusaku (friction) rwimyenda idafite kunyerera ruri munsi ugereranije nuwunyerera ugereranije;

2) Urusaku rw'akazu gakomeye rufite ni munsi ugereranije no gufata akazu kashe;urusaku rw'akazu ka pulasitike ruri munsi yo kwishyiriraho akazu kavuzwe haruguru;umubare wimipira ni mwinshi, impeta yo hanze irabyimbye, kandi urusaku ruri hasi Na none ntoya,

3) Ibyuma bisobanutse neza, cyane cyane bifite ubunyangamugayo buhanitse bwibintu bizunguruka, bifite urusaku ruto ugereranije n’ibisobanuro bito.

4) Urusaku rwibikoresho bito ni ruto ugereranije nuruva runini.
