Nthawi yosintha
Pali mndandanda wazizindikiro zomwe zimawoneka ngati ma hinges atavala kapena kusweka, zomwe zimagwiritsidwa ntchito nthawi imodzi pakuzindikira ndikutsimikiza kwa msonkhano womwe uyenera kusinthidwa:
- pakuwunika kwakunja, kuwonongeka kwakukulu kwa chivundikirocho kunapezeka ndi zizindikiro za ukalamba, m'malo mwa mafuta osakaniza, kusakaniza dothi lonyowa ndi dzimbiri kwakhala kukugwira ntchito mkati mwa hinge kwa nthawi yayitali, palibe chifukwa chokonzekera izi. chiuno, chiyenera kusinthidwa;
- mosinthana motsatizana, kugunda kwamtundu kapena kulira kumamveka, komwe, pambuyo pokweza galimoto, kumawonekera bwino m'magalimoto;
- pamene galimoto ikugudubuza, phokoso limamveka kuchokera mkati mwa galimotoyo, ndipo podutsa pamtunda wocheperako, hinge yakunja imadziwonetsera;
- vuto lalikulu - galimotoyo imadulidwa kwathunthu, mipira yawonongeka, galimotoyo silingathe ngakhale kusuntha, m'malo mwake, phokoso limamveka pansi.
Kusinthanitsa hinji imodzi ndikoyenera ngati mukutsimikiza kuti ena onse sanatumikire nthawi yayitali ndipo ali bwino. Apo ayi, ndizomveka kumvera malangizo a wopanga ndikusintha msonkhano wa galimoto.
