ʻO ke koʻokoʻo Polish kekahi ʻano o ke koʻokoʻo omo kūikawā i hoʻopili ʻia me ke koʻokoʻo omo a me ke kaula lāʻau. Aia ma ka piko o ke koʻokoʻo sucker, pono e lawe i ka ikaika loa, no laila me ka nui o ke anawaena a me ke kila kila kiʻekiʻe ma mua o ke koʻokoʻo sucker, a maʻalahi ka ʻili.

1. ʻO ke koʻokoʻo Polish he ʻano o ke koʻokoʻo omo kūikawā i hoʻopili ʻia me ke koʻokoʻo sucker a me ka hanger beam. Aia ma ka piko o ke koʻokoʻo sucker, pono e lawe i ka ikaika loa, no laila me ka nui o ke anawaena a me ke kila kila kiʻekiʻe ma mua o ke koʻokoʻo sucker, a maʻalahi ka ʻili.

2.Main hana:

Hoʻohui ʻia me ka hoʻopaʻa ʻana i loko o ka pahu pahu e hoʻopaʻa i ke poʻo maikaʻi a pale i ka hōʻike ʻana i ka ʻaila, kinoea, wai.

ʻO ka mea hoʻohui manawa ma waena o ke koʻokoʻo sucker a me ka pale poʻo miula

Ho'āʻo kiʻi hōʻailona hoʻopau.

E hoʻopau i nā hana poʻo luawai like ʻole, e like me ke kuʻi ʻana i ka pauma, hoʻoponopono i ka hoʻonohonoho ʻana i ka pauma.
