Kupanga kwamakono kwa mafakitale, opereka amagwiritsidwa ntchito kwambiri. Sizingangopulumutsa ndalama pobwezeretsa anthu ogwira ntchito, komanso onjezani ntchito yogwira ntchito. Contraceus amabwera kukula kwambiri. Pali onyamula zingwe osinthika, opondera master la lamba, opondera amba a lamba, otumiza mbale ndi otero. Shanghai yuyin akufotokozera mwachidule malo okhazikitsa a lamba.
1. Ikani shaft yosinthika pamlomo pachitsulo cha core ya lamba, ndikuyika lamba. Musanayike pa alumali, samalani kuti musabwezenso gawo la guluu lam'mwambamwamba komanso lotsika.
2. M'malo antchito omwe sioyenera kumenyedwa, lamba wa lamba uja amatha kutsogoleredwa, ndipo lamba wokhotakhota kuyenera kukhala ndi radius yokwanira yopepuka popewa kuwonongeka kwa lamba wonyamula. Kuletsedwa kuyika zinthu zolemera pa lamba lonyamula pamalo opindika.

3. Ngati lamba wonyamulayo uyenera kusinthidwa, lamba watsopano ukhoza kulumikizidwa ndi lamba wakale, ndipo kuchotsedwa kwa lamba ndikuyika kwa lamba watsopano wovomerezeka ukhoza kuchitika nthawi yomweyo.
4. Chifukwa chambala cha lamba chikuyenda molunjika, wotulutsa wakale wa lamba ukhoza kudulidwa nthawi iliyonse. Kuti alunthidwe a lamba akuyenda motsogozedwa, malo odulira ayenera kusankhidwa kuti alepheretse lamba chifukwa chokana kuwongolera chifukwa cha kulemera kwake.
5. Atayika lamba watsopano pa lamba, sinthani kumapeto kwake, kenako ndikulumikiza chingwe chozungulira chodzigudubuza, ndipo sungani lamba wa ku Belt kudzera pa chipangizocho. Mukamasuntha, onetsetsani kuti muchepetse lamba wonyamula ndi chimango kuchokera kufinya.
6. Gwiritsani ntchito cemple kumapeto kwa lamba wonyamula wambani, ndikulimbana ndi chitsirizo kudzera mu pulley mpaka lamba wokhotakhota usasunthe kwambiri pobwerera.
7. Konzani chida champhamvu pa lamba pa 100 ~ 150mm kutali ndi malo oyambira.
