Komanso, pambuyo pa kuthamanga kwa 50 Km, yamphamvu mutu gasket ndi vacuum mpope adzafunsidwa m'malo.
Zomwe zimayambitsa kugwedezeka kwa injini ndi phokoso losakhala lachilengedwe nthawi zambiri zimakhala muzitsulo za nthawi kapena unyolo wotambasuka. Pambuyo pa kuthamanga kwa makilomita 100-150, mavuto amenewa si achilendo konse.
Kuti muchepetse mwayi wamavuto ndi injini, ndikofunikira kusintha mafuta munthawi yake, kapena nthawi zambiri, zomwe ziyenera kukhala zoyambirira komanso zolimbikitsidwa ndi wopanga. Kuphatikiza apo, ndikofunikira kuthira mafuta abwino ndikuwongolera munthawi yake.
