Ihame ryakazi ryibikoresho bitanyerera bishingiye cyane cyane kuburyo bwa ratchet. Ikariso ya ratchet ifite uburyo bwo guhuza imbere bugizwe nibikoresho byinshi hamwe nuruziga. Iyo ikiganza gitangiye, ibyuma bizunguruka ibikoresho byo kugereranya, nabyo bigakora imbaraga zinzira imwe yo kuzunguruka. Igishushanyo cyemerera umuzenguruko kuzunguruka mu cyerekezo kimwe gusa, haba ku isaha cyangwa ku isaha yo kugana ku isaha, kugirango uhambire cyangwa woroshye ibihingwa n'imbuto.
Ibikoresho bidafite kunyerera bifite ibimenyetso bikurikira: icya mbere, igishushanyo cyacyo kirasobanutse kandi gikomeye, hamwe nimbaraga zikomeye zo gufatana, ntibyoroshye kunyerera, kandi byoroshye gukoresha. Icya kabiri, ikiganza cya wrench gikoresha igishushanyo mbonera kandi gifite ibikoresho byo kurwanya kunyerera, birwanya kwambara kandi birwanya kunyerera, kandi byoroshye gufata. Byongeye kandi, ibyuma bitanyerera byifashishwa mubikoresho bikozwe cyane, nkibyuma bya karubone ndende, kugirango birambe kandi bisohoka cyane. Ibiranga bituma ibyuma bitanyerera bigenda neza kandi bikora neza.

Amabwiriza arambuye cyangwa intambwe zo gukoresha neza ibikoresho bitanyerera ni ibi bikurikira:
Ukurikije intambwe zavuzwe haruguru, urashobora kwemeza neza gukoresha neza ibikoresho bitanyerera kandi ukemeza umutekano nigikorwa cyibikorwa.
