Michina yekuchera ine simba inoita basa rakakosha mumapurojekiti akasiyana-siyana ekuvaka nekuchera. Michina iyi inoshanda zvakanyanya ine zvinhu zvakawanda zvinoshanda pamwe chete kuti ive nechokwadi chekuti inoshanda zvakanaka. Chimwe chezvinhu zvakadaro ivharuvhu yetsoka yemuchina wekugadzira, iyo inoshanda senzira yekudzora sisitimu yehydraulic yemuchina.
Mucheri wemugodhivharuvhu yetsoka yemutyairichikamu chakakosha chesystem yekudzora yemuchina wekuchera, zvichibvumira vashandisi kudzora kufamba uye mashandiro emuchina zviri nyore. Inoshanda seswitch yekudzora inotumira zviratidzo kune hydraulic system, ichiiraira kuti iite mabasa chaiwo akadai sekusimudza, kudzikisa, kutenderera, uye kutsausa ruoko rwemuchina wekuchera.
Chimwe chezvakanakira zvikuru kushandisa vharuvhu yepilot foot valvu yekuvhima ndeyekudzora kwainoita. Vharuvhu yetsoka inobvumira vashandisi kuti vatonge mafambiro emuvhima, vachiona kuti muchina unoita mabasa nemazvo uye nemazvo. Kudzora uku kwakakosha, kunyanya kana uchishanda munzvimbo dzakamanikana kana dzakamanikana, uko kunyatsoita zvinhu nemazvo kwakakosha kudzivirira tsaona kana kukuvara kwezvivakwa zvakakomberedza.
Uyezve, vharuvhu yetsoka yemuchina wekuchekerera inopa kuchengetedzeka kuri nani kune vanoshanda. Vharuvhu yetsoka inowanzo kuve nezvinhu zvakasiyana-siyana zvekuchengetedza zvakaita sevharuvhu yekurerutsira kumanikidzwa uye mabasa ekumira nekukurumidza. Zvinhu izvi zvinodzivirira mushandi nemuchina kubva mukukuvadzwa kunogona kukonzerwa nekumanikidzwa kwakanyanya kana maitiro asingatarisirwi emuchina.
Kugara kwenguva refu chimwe chinhu chakakosha kana uchifunga nezvevharuvhu retsoka remuchina wekuchekerera. Mavharuvhu aya akagadzirwa kuti agone kumira mumamiriro ezvinhu akaoma anoshandiswa nevachekeri panzvimbo dzekuvaka. Akagadzirwa nezvinhu zvemhando yepamusoro, zvakagadzirirwa kudzivirira kusakara, mamiriro ekunze akaoma, uye kusangana nezvinhu zvinokuvadza zvakaita sematombo nevhu.
Kugadziriswa nekugadzirisa vharuvhu yetsoka yemuchina wekuchekerera kwakakosha kuti ive nechokwadi chekuti inoshanda zvakanaka. Kuongorora nguva dzose, kuchenesa, uye kuisa mafuta zvinodiwa kuti vharuvhu irambe ichishanda zvakanaka. Kugadziriswa nguva dzose kunobvumirawo kuti pave nematambudziko anogona kuitika, kudzivirira kugadzirisa kunodhura kana kuti nguva yekushanda.
Pakutenga vharuvhu yetsoka yemuchina wekuchekerera, zvakakosha kusarudza mutengesi kana mugadziri akavimbika uye ane mukurumbira. Kusarudza vharuvhu yetsoka yemhando yepamusoro kunoita kuti igare kwenguva refu uye igare kwenguva refu, zvichidzivirira kutsiva nekugadzirisa zvisina kufanira. Pamusoro pezvo, kutenga kubva kunzvimbo yakavimbika kunokutendera kuti ubatsirwe nehunyanzvi nerutsigiro rwehunyanzvi rwunopihwa nenyanzvi dzine ruzivo.
Mukupedzisa, vharuvhu yetsoka yemuchina wekugadzira (excavator pilot foot valve) inoshanda sechinhu chakakosha mukushanda zvakanaka kwevacheri. Kudzora kwayo kwakaringana, kuchengetedzeka, kugara kwenguva refu, uye nyore kugadzirisa kunoita kuti ive chikamu chakakosha che hydraulic system yemuchina. Pakusarudza vharuvhu yetsoka yemuchina wekugadzira (excavator pilot foot valve), zvakakosha kusarudza chigadzirwa chemhando yepamusoro kubva kumutengesi ane mukurumbira kuti ave nechokwadi chekuti inoshanda zvakanaka uye inogara kwenguva refu. Nekudyara mari muvharuvhu yetsoka yekurudyi, makambani ekuvaka nekuchera migodhi anogona kuwedzera kushanda zvakanaka uye kuchengetedzeka kwevacheri vavo, zvichikonzera kupedzwa kweprojekiti kunobudirira uye nenguva.
