Uhlalutyo lwezizathu kunye nempazamo yokungazithembi kwesantya esingazinzanga se-Excavators

Uhlalutyo lwezizathu kunye nempazamo yesantya esingazinzanga se-Excavators: Ukubonakaliswa kwesantya esingazinzanga ye-injini kukuba xa i-idal i-idal, iguquka, okanye kukho i-pibration, ibangela ukuba kubekho i-fais yequbuliso. Uhlalutyo oluvakalayo unolwazi ngolu hlobo lulandelayo:
Kukho umoya kwisekethe yeoyile.
② Isibonelelo se-Wliel osweleyo kwisekethe yeoyile esezantsi.
③ Isixhobo esingenamsebenzi esizinzileyo sahlengahlengiswa ngokungafanelekanga.
④ I-Amisting Atomize isuswe yintsholongwane yepetroli.
