Uma kuqhathaniswa nomshini wokunyathelisa ojwayelekile we-hydraulic, imishini yokunyathelisa ye-servo hydraulic inezinzuzo zokonga amandla, umsindo ophansi, ukukhuphuka okuncane kwezinga lokushisa, ukuguquguquka okuhle, ukusebenza kahle okuphezulu, nokugcinwa kalula, futhi ingangena esikhundleni semishini yokunyathelisa evamile ekhona. Umshini wokunyathelisa we-servo hydraulic ikakhulukazi wakhiwe ithebula elisebenzayo eligudlukayo, ikholomu yomhlahlandlela, isilinda esiyinhloko, uhlelo lwe-hydraulic, uhlelo lukagesi, inzwa yokucindezela, i-servo motor, namapayipi njll.
