Ho?okomo ?ia kēia huahana me ?elua mau pahu hydraulic, e lawelawe ana kēlā me kēia i kahi hana ko?iko?i a ?oko?a. Ho?opa?a pa?a ?ia ho?okahi cylinder ma lalo o ka lima excavator. ?A?ole ia e hā?awi wale i ke kāko?o ko?iko?i akā hana pū kekahi ma ke ?ano he lever, e ho?onui ana i ka pono mechanical i ka wā o ka hana.

Ho?opili ?ia ka pahu ?elua i ke kumu o ka mea wehe a?a. ?O ka mana hydraulic e ho?olalelale i kēia cylinder e ho?olō?ihi a ho?iho?i. Ho?onohonoho pono ?ia kēia hana e wāwahi i nā a?a kumulā?au, e hō?emi pono i ke kū?ē ?ana i ka wā o ke ka?ina o ka ?oki ?ana a me ka unuhi ?ana i nā a?a kumulā?au, no laila e ho?oma?ama?a i ke a?a.

Ma muli o ka ho?ohana ?ana o kēia huahana i ka ?ōnaehana hydraulic like me ka hammer hydraulic, ?o ka cylinder i ho?onoho ?ia ma lalo o ka lima he koi kūikawā. Pono ia e huki i ka aila hydraulic mai ka pahu lima. Ma ka hana ?ana pēlā, hiki iā ia ke ho?ohui i kona ho?onui a me ka ho?iho?i ?ana me kēlā o ka pahu pahu. He kī kēia ho?onohonoho ?ana i ka loa?a ?ana o ka hana ki?eki?e - kūpono a ki?eki?e - ka wikiwiki, e hiki ai i nā mea hana ke ho?okō i nā hana wehe a?a me ka ?oi loa o ka huahana.
