Njira zenizeni zosinthira mzere wakunja wa zenera ndi izi:
Konzani zida zomwe mungafunike pochotsa zokongoletsa zonse za pawindo, screwdriver yaying'ono, screwdriver yayikulu, ndi spline ya t-20
Chivundikiro chaching'ono chakuda chinapezeka m'mbali mwa chitseko, chomwe chinamangirira zomangira kunja kwa zenera, chinatulutsa screwdriver yaying'ono, ndipo chinagwiritsa ntchito screwdriver yaying'ono kuti chichotse chivundikiro chaching'ono chakuda pansi, samalani kuti chikhale chopepuka mukamachotsa, musakanda utoto wa chitseko, ndikuyika chivundikiro chaching'ono chakuda pansi.
Mukapeza mkati mwa sikuru yomwe imagwirira kunja kwa zenera, tulutsani spline ya t-20, ndipo gwiritsani ntchito spline ya t-20 kuchotsa sikuru iyi.
Kuchotsa zigawo zakunja. Tulutsani screwdriver yayikulu, gwiritsani ntchito screwdriver yayikulu kuti muchotse pang'onopang'ono m'mphepete mwa zenera kunja kwa bala, kuti zenera lakunja kwa bala limasulike. Gwiritsani ntchito chala chanu kugwira zenera lakunja kwa bala, kenako pang'onopang'ono mmwamba, pang'onopang'ono zenera lakunja kwa bala likulekanitsidwa ndi m'mphepete mwa chitseko, onetsetsani kuti pang'onopang'ono, pang'onopang'ono kuti lisweke, mphamvu zambiri, n'zosavuta kusokoneza zenera lakunja kwa bala. Kotero batten yakunja imachotsedwa bwino.
Kenako ikani yatsopano.
