ʻO ka moʻomeheu ʻoihana

ʻUhane ʻoihana: hoʻomanawanui, hoʻoikaika no ka maikaʻi loa, ʻoi loa

ʻO ka hihi ʻoihana: e lilo i alakaʻi nui ʻana i nā mea hana hana excavator

Pahuhopu: E lilo i alakaʻi nui o nā hāmare haʻihaʻi hydraulic

ʻO ke akeakamai ʻoihana: hoʻokumu paʻa, hana hou e like me ka ʻuhane

ʻO ke kulekele maikaʻi: kūpono, mālama i ka hoʻomaikaʻi, hāʻawi i nā mea kūʻai aku me nā huahana maikaʻi a me nā lawelawe kūpono, no laila e hoʻomaikaʻi mau ʻia ka ʻōnaehana hoʻokele ʻoihana.
