Kusungirako
Njira zopewera mayendedwe: Musananyamuke, yang'anani ngati chotengeracho chatha ndikusindikizidwa, ndikuwonetsetsa kuti chidebecho sichikutha, kugwa, kugwa kapena kuwonongeka panthawi yamayendedwe.Ndizoletsedwa kusakaniza ndi ma asidi, okosijeni, chakudya ndi zowonjezera zakudya.Pa zoyendera, magalimoto oyendera azikhala ndi mitundu yofananira ndi kuchuluka kwa zida zozimitsira moto ndi zida zadzidzidzi zomwe zatuluka.Ndipo ayenera kutetezedwa ku kuwala kwa dzuwa, mvula ndi kutentha kwakukulu ndi koyenera kuyendetsa molingana ndi njira yotchulidwa, ndipo musakhale m'madera okhala ndi malo okhala ndi anthu ambiri;
Kusamala Posungira
Sitolo yosindikizidwa mu nkhokwe yozizira komanso yolowera mpweya wosiyana ndi okosijeni ndi zamchere ndipo pewani kusungirako kosakanikirana.Khalani kutali ndi moto ndi gwero la kutentha ndi kuwala kwa dzuwa. ziyenera kusungidwa zida zozimitsa moto zamitundu yosiyanasiyana ndi kuchuluka kwake ziyenera kuperekedwa.Malo osungirako ayenera kukhala ndi zipangizo zoyenera kuti zikhale ndi kutayikira;
Kusunga Kusamala
Mlandu wamba wamatabwa kunja kwa botolo la ampoule;wamba matabwa mlandu kunja ya threaded galasi botolo, chitsulo kapu mbamuikha galasi botolo, botolo pulasitiki kapena zitsulo mbiya (akhoza);bokosi lodzaza pansi, fiberboard box kapena plywood box kunja kwa botolo lagalasi lopangidwa ndi ulusi, botolo lapulasitiki kapena mbiya ya tinplate (can).
