1, sangathe kuthamanga

Pamene chosefera chilephera kugwira ntchito bwino, mota ndi mabearing sizigwira ntchito bwino chifukwa cha kutentha kochepa. Vutoli nthawi zambiri limachitika pamene chophimba chogwedezeka chayikidwa panja popanda njira zodzitetezera. Kuti tithetse vutoli, titha kuyika chophimba choteteza, kutenga njira zodzitetezera ku zigawo za mota ndi mabearing, ndikuwonjezera antifreeze ku zigawo za mota ndi mabearing kuti mafuta asasungunuke;

2, ntchito yotsika yowunikira

Vutoli limayamba chifukwa cha kutsekeka kwa madzi. M'nyengo yozizira, kutentha kumakhala kochepa, kuzizira ndi kumamatira ku sikirini kumachitika poyesa zinthu zomwe zili ndi msonkho, zomwe zimachepetsa mphamvu yoyezera. Yankho la vutoli likhoza kuwonjezera kutentha kwa madzi kwa zinthuzo mkati mwa mulingo wovomerezeka (nthawi zambiri ndibwino kuzisunga pa 10 ℃), ndikuyeretsa sikirini nthawi yomweyo ntchito yoyezera ikatha kuti muwonetsetse kuti palibe madzi omwe akutsalira pamwamba pa sikirini.

3. Kulephera pafupipafupi

Ngati vuto la makina otsekera silikudziwika bwino, yankho lokhazikika ndikutsatira malangizo a ntchito. Yang'anani nthawi zonse ndikusamalira makina otsekera, ndikusunga zolemba za kusintha kwa ntchito panthawi yosintha. Kusamalira chophimba chogwedezeka pamalo ozizira kwambiri ndikofunikira kwambiri. Chophimba chogwedezeka chokha chomwe chili ndi khalidwe labwino ndi chomwe chingapirire mayeso a nyengo yozizira kwambiri.
