1. Kuchita kwatsimikizira kuti pakugwiritsa ntchito mano a chidebe chofufutira, mano akunja a chidebe amavala 30% mwachangu kuposa mano amkati.Ndibwino kuti pakatha nthawi yogwiritsira ntchito, malo amkati ndi akunja a mano a ndowa ayenera kusinthidwa.
2. Pogwiritsa ntchito mano a ndowa, zimatengera malo ogwira ntchito kuti mudziwe mtundu wa mano a ndowa.Nthawi zambiri, mano a chidebe chathyathyathya amagwiritsidwa ntchito pokumba, mchenga wosasunthika, ndi nkhope ya malasha.Mano a ndowa amtundu wa RC amagwiritsidwa ntchito kukumba miyala yayikulu yolimba, ndipo mano a ndowa amtundu wa TL amagwiritsidwa ntchito kukumba nsonga zazikulu za malasha.Mano a ndowa a TL amatha kupititsa patsogolo zokolola za malasha.Pogwiritsira ntchito, ogwiritsa ntchito nthawi zambiri amakonda mano a ndowa amtundu wa RC.Ndibwino kuti musagwiritse ntchito mano a ndowa amtundu wa RC pokhapokha ngati ndizochitika zapadera.Ndi bwino kugwiritsa ntchito mano a chidebe chathyathyathya, chifukwa mano a ndowa amtundu wa RC amatha pakapita nthawi.Amachepetsa kukana kukumba ndikuwononga mphamvu, pamene mano a chidebe chathyathyathya nthawi zonse amakhalabe pamwamba pa nthawi yovala, zomwe zimachepetsa kukana kukumba ndikusunga mafuta.
3. Njira yoyendetsera galimoto ya dalaivala wofukula ndiyofunikanso kuti pakhale kupititsa patsogolo kagwiritsidwe ntchito ka mano a ndowa.Dalaivala wofukula ayesetse kuti asatseke chidebecho pokweza boom.Ngati dalaivala akweza galimotoyo, amatseka chidebecho nthawi yomweyo.Mano a ndowa adzakhala pansi pa mphamvu yokoka mmwamba, yomwe idzang'amba mano a ndowa kuchokera pamwamba, motero kung'amba mano a ndowa.Chisamaliro chapadera chiyenera kuperekedwa ku mgwirizano wa zomwe zikuchitika mu ntchitoyi.Madalaivala ena ofukula nthawi zambiri amagwiritsa ntchito mphamvu zambiri pokulitsa mkono ndi kutumiza mkono, ndipo mwamsanga "kugogoda" chidebe pa thanthwe kapena kugwetsa chidebecho pa thanthwe ndi mphamvu, zomwe zimaphwanya mano a ndowa.Kapena ndikosavuta kuthyola ndowa ndikuwononga mikono yakumtunda ndi yakumunsi.
4. Kuvala kwa mpando wa dzino kulinso kofunika kwambiri pa moyo wautumiki wa mano a ndowa a chofufutira.Ndibwino kuti musinthe mpando wa dzino pambuyo pa 10% - 15%, chifukwa cha kuvala kwakukulu pakati pa mpando wa dzino ndi mano a ndowa.Pali kusiyana kwakukulu pakati pa mano, kotero kuti mgwirizano pakati pa mano a ndowa ndi mpando wa dzino, ndi mfundo ya mphamvu yasintha, ndipo mano a ndowa amasweka chifukwa cha kusintha kwa mphamvu.
5. The excavator dalaivala ayenera kulabadira ngodya kukumba pa ntchito, yesetsani kumvetsa pamene kukumba, mano chidebe ndi perpendicular kwa nkhope yogwira ntchito pamene kukumba pansi, kapena camber inclination ngodya si wamkulu kuposa madigiri 120, kotero ngati kupewa kuthyola mano a ndowa chifukwa chokonda kwambiri..Komanso samalani kuti musagwedeze mkono wokumba kuchokera mbali imodzi kupita kwina pamene pali kukana kwakukulu, zomwe zidzachititsa kuti mano a ndowa ndi mano athyoke chifukwa cha mphamvu zambiri kumanzere ndi kumanja, chifukwa ndondomeko yamakina amitundu yambiri ya mano a ndowa. saganizira za kumanzere ndi kumanja mphamvu.kupanga.
