A. Kukonza zosefera za mpweya
a.Zosefera zimayenera kusamalidwa kamodzi pa sabata.Chotsani chinthu chosefera, kenako gwiritsani ntchito mpweya woponderezedwa wa 0.2 mpaka 0.4Mpa kuti muwuze fumbi pagawo losefera.Gwiritsani ntchito nsalu yoyera kupukuta dothi pakhoma lamkati la chipolopolo cha mpweya.Pambuyo pake, yikani zosefera.Mukayika, mphete yosindikizira iyenera kukhala yogwirizana ndi nyumba ya fyuluta ya mpweya.
b.Nthawi zambiri, zosefera ziyenera kusinthidwa pa maola 1,000 mpaka 1,500.Mukagwiritsidwa ntchito kumalo odana, monga migodi, fakitale ya ceramics, mphero ya thonje, ndi zina zotero, tikulimbikitsidwa kuti tisinthidwe pa maola 500.
c.Mukamatsuka kapena kusintha zinthu zosefera, pewani zinthu zakunja kulowa mu valve yolowera.
d.Muyenera kuyang'ana pafupipafupi ngati pali kuwonongeka kapena kupindika kwa chitoliro chowonjezera.Komanso, muyenera kufufuza ngati olowa ndi lotayirira kapena ayi.Ngati pali vuto lililonse pamwambapa, ndiye kuti muyenera kukonza nthawi yake kapena kusintha magawowo.
B. Kusintha Sefa ya Mafuta
a.Muyenera kusintha fyuluta yatsopano yamafuta ndi wrench yodzipatulira, ya compressor yatsopano yomwe yakhala ikugwiritsidwa ntchito kwa maola 500.Asanakhazikitse fyuluta yatsopano, ndi bwino kuwonjezera mafuta owononga, kenaka pukuta chosungira ndi dzanja kuti asindikize chinthu chosefera.
b.Ndikofunikira kuti zinthu zosefera zisinthidwe m'malo mwa maola 1,500 mpaka 2,000.Mukasintha mafuta a injini, muyeneranso kusintha gawo la fyuluta.Kuzungulira m'malo kuyenera kufupikitsidwa, ngati fyuluta ya mpweya ikugwiritsidwa ntchito m'malo ovuta kwambiri.
c.Zosefera ndizoletsedwa kugwiritsidwa ntchito nthawi yayitali kuposa moyo wake wautumiki.Apo ayi, idzatsekedwa kwambiri.Valavu yodutsa idzatseguka pokhapokha kupanikizika kosiyana kukadutsa mphamvu yokwanira ya valve.Zikatere, zonyansa zimalowa mu injini limodzi ndi mafuta, zomwe zimapangitsa kuwonongeka kwakukulu.
C. M'malo Olekanitsa Mafuta a Air
a.Wolekanitsa mafuta a mpweya amachotsa mafuta opaka mumlengalenga.Pansi pa ntchito yanthawi zonse, moyo wake wautumiki ndi maola 3,000 kapena apo, zomwe zimatengera mtundu wamafuta opaka mafuta komanso kusefa bwino.M'malo ogwiritsidwa ntchito onyansa, nthawi yosamalira iyenera kufupikitsidwa.Komanso, pre air fyuluta ingafunike kuti zitsimikizire kugwira ntchito kwanthawi zonse kwa air compressor ngati zili choncho.
b.Pamene cholekanitsa chamafuta am'mlengalenga chikafika kapena kuthamanga kwapadera kupitilira 0.12Mpa, muyenera kusintha cholekanitsa.
