1. Chikamu chinodonhedza mafuta chemuchina wekuderedza crane:
① Nzvimbo yakabatana yebhokisi rekuderedza simba, kunyanya rekuderedza simba rakamira, yakanyanya kuoma.
② Zvivharo zvekupedzisira zvemubato wega wega wedhirekita, kunyanya maburi emubato wezvivharo zvepakati.
③ Pakavharidzirwa gomba rekutarisa rakati sandara.
2. Kuongororwa kwezvikonzero zvinokonzera kubuda kwemafuta:
① Nzvimbo yekubatanidza bhokisi haina kusimba uye nzvimbo yacho haina kusimba.
② Bhokisi rinoshanduka, uye pamusoro pemajoini nemaburi ebheyaringi zvinochinja zvinoenderana, zvichiita mipata.
③ Mukana uri pakati pechifukidziro chebheyaringi neburi rebheyaringi wakakura zvakanyanya, uye mugero wemafuta unodzoka mukati mechifukidziro wakavharwa. Mhete dzekuvhara dzemubato nechifukidziro dzakwegura uye dzakakanganisika, dzichirasikirwa nekushanda kwadzo kwekuvhara.
④ Huwandu hwemafuta hwakawandisa (huwandu hwemafuta hahufanirwe kupfuura chiratidzo chiri patsono yemafuta). Nzvimbo yekubatana paburi rekutarisa haina kuenzana, gasket rekuvhara rakakuvara kana kuti harisipo, uye kuvhara hakuna kusimba.
3. Matanho ekudzivirira kubuda kwemafuta:
① Iva nechokwadi chekuti nzvimbo dzakabatana dzemuchina wekuderedza simba dziri pedyo, uye nzvimbo dzesimbi dzinofanira kuputirwa nechisimbiso kuti dzisvike pazvinodiwa zvehunyanzvi.
② Vhura mugero wemafuta anodzoserwa pamusoro pejoini repasi, uye mafuta akadururwa anogona kudzokera mutangi remafuta ari pamugero wemafuta anodzoserwa.
③ Isa chivharo chenaironi chemvura kana chimwe chivharo panzvimbo dzese dzinobuda mafuta dzakadai sepanosangana bhokisi, maburi ekuvhara magumo ebheyaringi, uye chivharo chemafuta anoona.
④ Pazvinhu zvine kutenderera kwakafanana nematanda uye maburi ekufukidza, mhete dzerabha dzinoshandiswa.
⑤ Sezvo tembiricha yemwaka ichichinja, mafuta ekuzora akakodzera anofanira kusarudzwa zvichienderana nemitemo.
⑥ Chinodzikisa mafuta chinoshandisa molybdenum disulfide semafuta ekuderedza kuburitswa kwemafuta.
