Kumeta mitengo yometa ndi nthambi zamaluwa zida zodulira: zotetezeka komanso zothandiza, kupulumutsa ndalama zogwirira ntchito, zotsika mtengo, zotsika mtengo, zotuluka mwachangu!
Kuchuluka kwa ntchito: kudulira nthambi za m'munda ndi kudula mitengo.
·Thupi lonse la chodulira nsungwi limapangidwa ndi mbale yapadera yachitsulo ya manganese yosamva kuvala (yolimba kwambiri, yosamva kuvala)
·Kutenga valavu yotetezedwa kuti cylinder yamafuta isagwe mwachilengedwe.Kupanga kwakukulu kwa silinda yamafuta kumawonjezera mphamvu yakumeta ubweya wa zida
Pogwiritsa ntchito masamba a aloyi osinthika, amatha kudula mpaka 120mm ~ 500mm wamatabwa olimba.
