ʻO ke kūʻai ʻana i kahi ʻāpana me ka hana maikaʻi loa ʻo ia wale nō ka hana mua. ʻO ka mea nui ka mālama ʻana i ka hana o kēlā me kēia lā. ʻO ka hana maikaʻi o ka mālama ʻana a me ka hana maʻamau ʻaʻole hiki ke hōʻemi wale i nā hemahema o nā lako, akā e hōʻemi hoʻi i nā poho pono ʻole, hoʻonui nui i ke ola lawelawe o nā mea hana a hoʻemi i ke kumukūʻai o ka hoʻohana.

Makaʻu nā mea hana mīkini nui e like me nā mea hoʻohui asphalt e loaʻa nā hemahema a pili i ka hana a me ka lako. ʻAʻole hiki ke pale ʻia kekahi mau poho i ka wā o ke kaʻina hana, akā ke kumu pinepine ʻia kekahi mau hemahema ma muli o ka mālama pono ʻole, hiki ke pale ʻia i ka wā mua. No laila, ʻo ka nīnau, pehea mākou e mālama pono ai i nā mea hana a hana i kahi hana maikaʻi o ka mālama ʻana i nā mea hana i kēlā me kēia lā?
Wahi a ka noiʻi, ʻo 60% o nā hemahema o nā mīkini a me nā mea hana ma muli o ka lubrication maikaʻi ʻole, a ʻo 30% ke kumu o ka paʻa ʻole. Wahi a kēia mau kūlana ʻelua, ʻo ka mālama ʻana i kēlā me kēia lā o nā mea hana mechanical e pili ana i: anti-corrosion, lubrication, adjustment, and tightening.
ʻO kēlā me kēia neʻe ʻana o ke kahua hoʻopaʻa ʻana e nānā inā ua hemo nā bolts o ka motika oscillating; e nānā inā ua hemo nā bolts o nā ʻāpana like ʻole o ka pahu pahu; e nānā inā pa'a nā wili/'a'ole ka'a; e nānā inā heʻe ke kāʻei. Ma hope o 100 mau hola o ka hana, e nānā i ka pae ʻaila a me ka leakage.
Inā pono, e hoʻololi i nā sila i pohō a hoʻohui i ka momona. E hoʻohana i ka ʻaila mineral ISO viscosity VG220 e hoʻomaʻemaʻe i nā lua ea; e kau i ka aila i ka wili hoʻopaʻa ʻana o ka mea lawe kāʻei. Ma hope o 300 mau hola hana, e hoʻopili i ka momona i hoʻokumu ʻia i ka calcium i nā noho kuʻi o nā wili nui a hoʻokele ʻia o ke kāʻei hānai (inā puka ka ʻaila); e hoʻopili i ka momona i hoʻokumu ʻia i ka calcium i nā noho kuʻi o nā wili nui a i hoʻokele ʻia o ke kāʻei palahalaha a me ke kāʻei inclined.
