Isixhumanisi sokucubungula ukulethwa okubuthayo sihlukaniswe ngokuphelele kusuka lapho kusebenza ukucubungula okushisayo, ngoba uma ingxenye ye-pulley yomthombo wokubulala isemthethweni, kufanele icubungulwe ngokujwayelekile, ukuze kusetshenziswe kangcono ukuhlinzwa okujwayelekile komthandela wokuqina. Ngemuva kwakho konke, ukuthwala izinyoba lapho kusetshenziswa, ingxenye ye-pulley iyingxenye ebalulekile engathwala zonke izinto, ngakho-ke kufanele sinake izici eziningi lapho sibhekene nesixhumanisi sokusebenza esishisayo sokuqina kokuqina. Amanothi achazwa ngemininingwane eminingi.
Ngokuvamile, lapho ukuthwala izinzwa kushisa kusebenza, izinqubo ezifanele zokusebenza kufanele zenziwe kuqala.

Izinyathelo ezijwayelekile zenqubo yilezi: Ukwakha → Ukuqhuma → Ukucimana nokusula Enye yezindawo zomjaho ilangabi ilangabi laqedwa ukwakha iqembu elithambile. Ibhande elibizwayo le ndawo yindawo ebingakaze ishiswe ukushisa. Ukwakheka kwebhande elithambile kuyadingeka kwinqubo yokwelashwa kokushisa. Ehlelweni lokugcina lokwelashwa kokugcina, ngoba ububanzi bendilinga yomjaho wobunzi bokulala buthandela bukhulu, ilangabi lokugunda livame ukusetshenziswa. Indlela ukusebenzisa i-acetylene ukushisa ingaphezulu komsebenzi wokusebenza ukuze ulukhuni bese wengeza amanzi. Ukupholisa, le nqubo yenziwa ngokuqhubekayo. Isibhamu esivuthayo selangabi nesibhamu samanzi sihlanganiswa ndawonye ngenkathi senza umjikelezo kanye nombuthano we-workpie. Ehlelweni lokugcina lokwelashwa kokugcina, ngoba ububanzi bendilinga yomjaho wobunzi bokulala buthandela bukhulu, ilangabi lokugunda livame ukusetshenziswa. Indlela ukusebenzisa i-acetylene ukushisa ingaphezulu kwendawo yokusebenza ukuze ilukhuni bese ingezela amanzi ukuze uyipholise. Isibhamu esishisekayo esishisekayo nesibhamu samanzi sifakwe ndawonye ngenkathi senza ukunyakaza okujikelezayo embuthanweni we-workpie.

Lapho ukunyakaza sekusondele kuma-degree angama-360, ukufudumeza kanye namanzi kumiswa ngokushesha. Lokho wukuthi, izindawo eziyindilinga zokushisa nokufafaza amanzi azidluli. Imifantu ekusebenzeni kwenzeke kungenzeka uma izindawo zombuthano lapho kufakwa khona isifufula sokushisa nesifufula samanzi (ukwelashwa kokushisa e-angle enkulu kune-360 degrees embuthanweni). Ububanzi be-Tangentint yendawo engashintshiwe ngokujwayelekile yi-15 mm. Le ndawo engu-15mm ibizwa ngebhande elithambile elisendandatho yokubulala. EsiNgisini, kuvame ukuba yindawo ethambile. Ngaphansi kwezimo ezijwayelekile, i- "S" yensimbi "ithayisiwe esimweni lapho ibhande elithambile likhona kulokhu kusiza ukukhombisa isikhundla esithile sebhande elithambile. Imikhiqizo evamile yasekhaya noma yasekhaya ivame ukuba nophawu olubaluleke kakhulu.

Ngokwezinyathelo ezifanele zokubutha ukuqina kokuqina kwinqubo eshisayo yokusebenza, lokhu kuyafana nesingeniso esifanele esikwenzele ngaphezulu, ngakho-ke kufanele sinake futhi sikunake ngendlela efanayo. Ngakho-ke, ukusebenza okuyikho kwe-pulley ingxenye yokubutha izinsolo kuqinisekiswa ngempumelelo.
