1. Kana iyo inotungamira waya ye
carbon brushyakafukidzwa ne insulating chubhu, inofanira kuiswa mu insulating carbon brush holder; kana tambo inotungamira iri waya yemhangura isina chinhu, inofanira kuiswa muvhu kabhoni brashi inobata.
2. Pakuisa iyo
carbon brushpane kabhoni brashi inobata, teerera kune kutungamira kwenzvimbo yakakombama. Kana iyo kabhoni bhurashi yakaiswa kumashure, iyo yekubata kumeso ichave yakanyanya kudiki, uye kugadzirwa kwemagetsi kuchave kushoma kana kusagadzirwa.
3. Iyo kabhoni brashi inofanira kukwanisa kusimuka uye kudonha zvakasununguka mu carbon brush inobata. Kana kadhi racho rakabudiswa, chikamu chakawedzerwa chinofanira kubviswa.
4. Iyo carbon brush spring inofanira kudzvinyirirwa pakati pe
carbon brushkudzivirira kusapfeka kwakaenzana.
5. Nzvimbo yekuonana pakati pecarbon brushuye commutator haifaniri kunge iri pasi pe3/4 yehuwandu hwekusangana kwepamusoro, uye carbon brush haifaniri kuva nemafuta emafuta.
