1. Gawo lotayira mafuta la chochepetsera cha crane:
① Pamwamba pa bokosi lochepetsera, makamaka chochepetsera choyima, ndizovuta kwambiri.
② Zipewa zomaliza za shaft iliyonse ya chochepetsera, makamaka mabowo a shaft ya zisoti.
③ Pachivundikiro chathyathyathya cha dzenje lowonera.
2. Kuwunika zomwe zimayambitsa kutayikira kwamafuta:
① Pamwamba pa bokosilo ndizovuta ndipo cholumikizira sichili chokhwima.
② Bokosilo limakhala ndi mapindikidwe, ndipo malo olumikizana ndi mabowo amasinthidwa molingana, kupanga mipata.
③ Kusiyana pakati pa chivundikiro chonyamula ndi dzenje ndi lalikulu kwambiri, ndipo poyambira mafuta obwerera mkati mwa chivundikirocho watsekedwa. Mphete zosindikizira za shaft ndi chivundikiro zakalamba ndi kupunduka, zomwe zimataya mphamvu yosindikiza.
④ Kuchuluka kwamafuta (mulingo wamafuta sayenera kupitilira chizindikiro cha singano yamafuta). Malo ophatikizana pa dzenje loyang'ana silofanana, gasket yosindikiza yawonongeka kapena ikusowa, ndipo kusindikiza sikuli kolimba.
3. Njira zopewera kutulutsa mafuta:
① Onetsetsani kuti malo olumikizirana a chochepetsera alumikizana kwambiri, ndipo zitsulo ziyenera kuphimbidwa ndi sealant kuti zigwirizane ndiukadaulo.
② Tsegulani poyambira mafuta pamalo olumikizirana, ndipo mafuta otayira amatha kubwerera ku tanki yamafuta motsatira poyambira mafuta.
③ Ikani chosindikizira cha nayiloni chamadzimadzi kapena chosindikizira china kumadera onse otayira mafuta monga malo olumikizirana a bokosilo, okhala ndi mabowo ophimba kumapeto, ndi chivundikiro chamafuta.
④ Pamalo okhala ndi kasinthasintha wachibale, monga ma shafts ndi mabowo ophimba, mphete zomata za mphira zimagwiritsidwa ntchito.
⑤ Pamene kutentha kwa nyengo kumasintha, mafuta oyenera odzola ayenera kusankhidwa malinga ndi malamulo.
⑥ Chotsitsa mwachangu chimagwiritsa ntchito molybdenum disulfide ngati mafuta kuti athetse kutuluka kwamafuta.
