1. Kuchita bwino kumangiriza: Mtanda waukulu wathyathyathya wodzigudubuza zomangira zimapangidwa ndi zida zamphamvu kwambiri, zomwe zimatha kumangitsa zigawo zosiyanasiyana palimodzi ndikusunga kukhazikika kwa zida.
2. Zosavuta kusokoneza: Ndi mapangidwe ake apadera amutu, amatha kumangika mosavuta kapena kusokoneza pogwiritsa ntchito screwdriver, kupulumutsa sitepe ya pre punching, kuti ikhale yosavuta kugwiritsa ntchito komanso kupulumutsa nthawi.
3. Kukana kwamphamvu kwa dzimbiri: Zomangira zozungulira zozungulira mutu wokhotakhota wokhazikika nthawi zambiri zimapangidwa ndi zida zapamwamba, ndipo pamwamba pake amapangidwa ndi mankhwala kuti apange filimu yakuda ya galvanized oxide, yomwe imakhala ndi dzimbiri labwino komanso zotsutsana ndi dzimbiri ndipo zitha kugwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta.
4. Mapangidwe osavuta: opangidwa ndi mutu, shaft, ndi ulusi, zosavuta kupanga ndi kugwiritsa ntchito.
5. Zogwiritsidwa ntchito kwambiri: Zili ndi ntchito zosiyanasiyana pazida zamakina, zomanga, kupanga mipando, zinthu zamagetsi, zamlengalenga ndi zina.
6. Mphamvu zokulirapo: Mutu wosalala wopangidwa ndi mtanda umalola kuti mtanda wooneka ngati wathyathyathya wodzigudubuza kuti ugwirizane bwino ndi zinthu zoyambira, kupangitsa kulumikizana kukhala kokhazikika komanso kodalirika, kokhala ndi mphamvu yonyamula katundu, komanso kukana bwino komanso kukameta ubweya kuposa zomangira zachikhalidwe.
7. Kukhazikika kwapamwamba: Mutu wathyathyathya wooneka ngati mtanda umapangitsa kuti mgwirizano ukhale wolimba komanso wodalirika, kuchepetsa kuthekera kwa kumasula.
