ʻOi aku ka maikaʻi o ka wili pōhaku 311.2mm (12 1/4″) i ka ʻeli ʻana i ka pōhaku waena. Hāʻawi kāna mau ʻoki polycrystalline i ka paʻakikī koʻikoʻi a me ke kūpaʻa ʻana i ka ʻaʻahu, e hōʻoiaʻiʻo ana i ke ola lawelawe lōʻihi a me ka hana ʻoki mau. Hoʻomaʻemaʻe pono nā nozzles hydraulic i nā ʻōpala pōhaku, e pale ana i ka paʻa ʻana a mālama i ka wikiwiki o ka ʻeli ʻana. Me 5 mau pahi, hoʻolaha like ia i ka ikaika ʻoki, e hōʻemi ana i ka haʻalulu a hoʻonui i ke kūpaʻa. Hoʻonui ke anawaena ʻoki 19mm i ka wehe ʻana i nā ʻāpana, ʻoiai ke kino kila e hāʻawi i ka ikaika kūkulu kiʻekiʻe e kū i nā kūlana pōhaku ʻino. I ka hui pū ʻana, hoʻonui kēia mau hiʻohiʻona i ka pono o ka ʻeli ʻana, hoʻemi i ka manawa downtime, a hōʻoia i ka hana hilinaʻi i nā ʻano pōhaku waena.
