Ke kila kila ʻaʻole laina ʻaʻole i hoʻopaʻa ʻia.
Ka mālama ʻana i nā ʻūhā Diaphragm
1. Ma mua o ka hoʻokomoʻana i ka valve diaphragm, e nānā pono inā pili nā kūlana hana o ka pipeline me ka laulā o ka hoʻohanaʻana i ka valve, a pono e hoʻomaʻemaʻeʻia ka lua o loko e pale ai i ka lepo mai ka paʻaʻana a iʻole ka hōʻinoʻana i nā'āpana sila.
2. Mai pena i ka ʻili o ka ʻili a me ka diaphragm me ka momona e pale ai i ka pehu ʻana o ka lāʻau a pili i ke ola lawelawe o ka valve diaphragm.
3. ʻAʻole ʻae ʻia ka huila lima a i ʻole ka mīkini hoʻoili no ka hāpai ʻana, a pāpā loa ʻia ke kuʻi ʻana.
4. I ka hana ʻana i ka valve diaphragm me ka lima, ʻaʻole pono e hoʻohana ʻia ka lever kōkua no ka pale ʻana i ka pōʻino o nā ʻāpana hoʻokele a i ʻole nā ʻāpana hoʻopaʻa ʻana ma muli o ka torque kiʻekiʻe.
5. Pono e mālama ʻia nā kīwī diaphragm i loko o kahi lumi maloʻo a hoʻoheheʻe ʻia, a pāpā loa ʻia ka hoʻopaʻa ʻana.Pono e hoʻopaʻa ʻia nā ʻaoʻao ʻelua o ka valve diaphragm stock, a ʻo ka wehe ʻana a me ka pani ʻana e wehe iki ʻia.
E hoʻoholo i nā hewa maʻamau o nā kīwaha diaphragm
1. ʻAʻole maʻalahi ka hana ʻana o ka huila lima: ①Ua piʻo ke kumu valve ②Ua poino ke kaula.
2. ʻAʻole hiki ke wehe a pani koke ka valve diaphragm pneumatic.
3. Leaka ma ka pilina ma waena o ke kino kiwi a me ka pāpale: ①Ua wehe ka pahu hoʻohui ②Ua haki ka ʻāpana o ka pahu pahu ①E hoʻopaʻa i ka pahu hoʻohui ②E hoʻololi i ke kino valve
