ʻO ka pōʻaiapuni mālama o ka zinc-aluminium alloy bushings e hilinaʻi nui ʻia ma ke ʻano hana a me nā kūlana hana.
Manaʻo ʻia ka nānā ʻana a me ka mālama ʻana:
Ka honua maloʻo maʻamau i loko: e nānā i hoʻokahi manawa i ka makahiki.
ʻO ka ʻāina haʻahaʻa a i waho paha: pono e nānā i hoʻokahi manawa i kēlā me kēia 6-9 mahina.
Kaiapuni ʻino loa (e like me nā wahi kahakai, kokoke i nā mea kanu kemika, a me nā mea ʻē aʻe): pono e hana ʻia ka nānā ʻana i kēlā me kēia 3-6 mahina.
Nā mea nānā nui:
E nānā inā he ʻōpala ka ʻili, ʻeleʻele (melemele a ʻeleʻele paha), pauka, a i ʻole nā hōʻailona ʻino ʻē aʻe;
E nānā inā ua hemo nā mea hoʻopaʻa (e like me nā bolts, brackets);
E nānā inā hōʻike ka hale i ka deformation a i ʻole ke kulou ʻana ma muli o ke kaumaha;
E nānā i nā wahi nāwaliwali e like me nā ʻaoʻao i ʻoki ʻia a i ʻole nā weld i ʻōpala a i ʻole ke kahe ʻana.
