Umunaniro ucuramye mu kuzunguruka bitewe nuburemere burenze urugero bumeze nkibimera biterwa nuduce tw’amahanga, kandi impande zazamuye zishobora gutera kunanirwa.Fenomenon: Mu cyiciro cyambere, ibyobo byagabanijwe hamwe no kuzunguruka ibintu bigenda bikwirakwizwa gusa ku gice cyizengurutse, amaherezo biganisha ku kugaragara.Ibi rimwe na rimwe bibaho hamwe na ferrule imwe gusa.Akenshi asimmetrike hagati yumuhanda.Impamvu: - Imizigo irenze urugero, imitwaro yo guhungabana - Imbaraga zo kwishyiriraho zanyujijwe mubintu bizunguruka Umuti: - Kurikiza amabwiriza yo kwishyiriraho - Irinde imitwaro iremereye hamwe n’imitwaro irenze urugero Umunaniro ukabije kubera kwishyiriraho nabi: Kubireba imipira ihuza imipira Muri rusange, harimo umunaniro muri agace kadahuza hafi y'urubavu ruto, reba Ishusho ya 46. Impamvu: - Guhindura bidakwiye - Guhuza axial idahagije cyangwa gufunga ibyuma bidafunze - Kwivanga cyane kwa radiyo Umuti: - Menya neza ko ibice bikikije - Gukosora neza Umunaniro bitewe no kudahuza .Mugihe gikabije, hazaba ibice munsi yigitereko, reba Ishusho ya 48.

Impamvu: Bitewe no kudahuza amazu cyangwa gutandukana kwa shitingi, impeta yimbere ihengamye ugereranije nimpeta yinyuma kandi itera imitwaro minini.Kubijyanye no gufata imipira, ibi bivamo imbaraga mumifuka yikiziriko (igice cya 3.5.4), kunyerera cyane kumihanda no kumipira yiruka kumpande zumuhanda.Kuri roller, inzira nyabagendwa iremerewe.Iyo impeta yegeranye cyane, inkombe yumuhanda hamwe nibintu bizunguruka bizikorera umutwaro, kandi guhangayika bizabaho.Nyamuneka reba "Inzira idahwitse" mu gice cya 3.3.1.2.Ingamba zo gukosora: - Koresha kwishyiriraho ibiciro - Kugabanya kudahuza - Kongera imbaraga za shaft 31 Suzuma ibiranga kwiruka no kwangiza umunaniro ukuweho.48: Umunaniro ubaho kumpera yumupira utwara umuhanda, nko hamwe nigihe kinini cyumutwaro (kwiruka kwiruka);ishusho ibumoso yerekana inkombe yumuhanda, kandi ishusho iburyo yerekana umupira.
