Mapangidwe atsopano awiri othamanga hydraulic chida chopepuka komanso chophatikizika, chida ichi ndi choyenera kugwira ntchito m'malo otsekeka.
Kukhala ndi phindu la kasupe zonyamula zonyamula kufa kumatha kupita patsogolo pogwiritsa ntchito dzanja limodzi, chifukwa chake kusiya dzanja lina laulere kuti liyike cholumikizira.
Kuti mugwiritse ntchito mosavuta komanso kutonthoza wogwiritsa ntchito, mutu wa chida ukhoza kuzunguliridwa mokwanira ndi madigiri a 180.
Valavu yotetezedwa yomangidwamo idzadutsa mafuta operekera mafuta pamene kupanikizika kwakukulu kukufika, ndipo kupanikizika kumafika, ndipo njira yotulutsa mphamvu imatha kugwiritsidwa ntchito mosavuta pamtundu uliwonse wa kuponderezedwa.
