ʻO ka hōʻoia maikaʻi: ʻO ke kaʻina hoʻomaʻamaʻa wela i hoʻopaʻa ʻia e hana i ka huahana me ka paʻakikī a ʻoi aku ka ikaika i ka hopena a me ke kūpaʻa ʻana. Loaʻa i kēlā me kēia loulou o ka hoʻoheheʻe ʻana i nā kaʻina hana mana, pono e loiloi a hōʻoia ʻia e ka WUJ Quality Inspection Department ma mua o ka haʻalele ʻana i ka hale hana e hōʻoia i ka maikaʻi o kēlā me kēia huahana i waho.
ʻO ka hōʻoiaʻiʻo:ʻo ka WUJ blow bar i hanaʻia me ka chromium kiʻekiʻe a iʻole nā mea kūikawā kūikawā e like me nā kūlana hana, me ka hana maikaʻi a me ka hana houʻana o ka huahana, a he mau mea maikaʻi loa kona ma luna o nā huahana o kaʻoihana like. Loaʻa iā WUJ kekahi mau kākoʻo ʻenehana loea a me nā mea hana kiʻekiʻe kiʻekiʻe ma luna o ka pūnaewele, hiki ke hoʻonohonoho ʻia e like me nā koi pilikino. Ma hope o ka hoʻoheheʻe ʻana i ka ʻepekema a me ke koʻikoʻi, ka hoʻolei ʻana a me ka mālama wela, ʻaʻole hiki i nā huahana ke hoʻomaikaʻi wale i ka pale ʻana i ka lole, akā hoʻomaikaʻi pū i ka nani o nā mea i haki.
ʻO ke kumu kūʻai kiʻekiʻe o ka hoʻokō ʻana: ʻo ka hoʻohana ʻana i ka pahu pahu chromium composite kiʻekiʻe e pālua i ka hana ʻana o ka crusher, hoʻemi i ke kumukūʻai hoʻolimalima o ka hoʻolei ʻana i ka lole, hoʻemi i ka poho pani ʻana ma muli o ka hoʻololi pinepine ʻana i nā ʻāpana, a hoʻomaikaʻi nui i ka hoʻihoʻi ʻana i ka hoʻopukapuka.
E hoʻomaopopo ʻo ka pā puhi ka ʻāpana lole nui o ka haʻi hope. Ma hope o kēlā me kēia pani ʻana, e nānā i kona ʻaʻahu ma ka puka nānā, ʻoi aku ka nui o ka leakage. I ka hihia o ka lole a i ʻole nā kumu ʻike ʻole ʻia, e ʻoluʻolu e hoʻololi iā lākou i ka manawa, a i ʻole e kelepona iā WUJ Company e noi i nā manaʻo ʻoihana a i ʻole nā hanana.
