Ngakhale nyundo yachitetezo ndi yaying'ono, imatha kugwira ntchito yofunika kwambiri panthawi yofunika.Pankhani ya ngozi m'galimoto, galimotoyo imakhala yotsekedwa, pansi pa mphamvu yamphamvu, kupotoza kwa chitseko sikungatsegulidwe, kugwiritsa ntchito nyundo yachitetezo kuswa galasi lazenera, kungathandize okwera kuthawa, nyundo yachitetezo pa. nthawi iyi kwenikweni ndi "nyundo yopulumutsa moyo".
Nyundo yopulumutsa moyo, yomwe imadziwikanso kuti nyundo yachitetezo, ndi chida chothandizira chothawa chomwe chimayikidwa mu kanyumba kotsekedwa.Nthawi zambiri imayikidwa m'zipinda zotsekedwa monga magalimoto momwe zimakhala zosavuta kuthawa.Pakachitika mwadzidzidzi monga moto mu kanyumba kotsekedwa monga galimoto kapena kugwera m'madzi, n'zosavuta kuchotsa ndi kuphwanya zitseko za mawindo a galasi kuti apulumuke bwino.
Nyundo yotetezera makamaka imagwiritsa ntchito nsonga ya conical ya nyundo yopulumutsa moyo, chifukwa malo okhudzana ndi nsonga ndi ochepa, choncho galasi likaphwanyidwa ndi nyundo, kupanikizika kwa malo okhudzana ndi galasi kumakhala kwakukulu (komwe kuli chofanana ndi mfundo ya pushpin), ndipo galasi lagalimoto limayendetsedwa ndi mphamvu yayikulu yakunja panthawiyo ndipo kusweka pang'ono kumachitika.Kwa galasi lopsa mtima, kusweka pang'ono kumatanthauza kuti kugawanika kwa nkhawa mkati mwa galasi lonse kumawonongeka, zomwe zimapangitsa kuti ming'alu ya kangaude iwonongeke nthawi yomweyo, panthawiyi, malinga ngati nyundo imaphwanyidwa pang'onopang'ono, zidutswa za galasi zikhoza kukhala. kuchotsedwa.
