Isimiso sokusebenza sokuphakama kwesibani sekhanda esilungisekayo:
Ngokwendlela yokulungisa, ivame ukuhlukaniswa ngokulungiswa ngesandla nangokuzenzakalela. Ukulungiswa ngesandla: ngokwezimo zomgwaqo, umshayeli ulawula i-engeli yokukhanyisa isibani sekhanda ngokuphendula isondo lokulungisa ukukhanya emotweni, njengokuzivumelanisa nokukhanya okuphansi lapho ukhuphuka kanye nokukhanya okuphezulu lapho wehla. Ukulungiswa okuzenzakalelayo: umzimba wemoto onomsebenzi wokulungisa ukukhanya okuzenzakalelayo ufakwe izinzwa eziningana, ezingabona ibhalansi eguquguqukayo yemoto futhi zilungise ngokuzenzakalelayo i-engeli yokukhanyisa ngohlelo oluhleliwe.
Ukuphakama kwesibani sekhanda kuyalungiseka. Ngokuvamile, kukhona inkinobho yokulungisa ngesandla ngaphakathi emotweni, engalungisa ukuphakama kokukhanya kwesibani sekhanda ngokuthanda kwayo. Kodwa-ke, isibani sekhanda sezinye izimoto zikanokusho ezisezingeni eliphezulu silungiseka ngokuzenzakalelayo. Nakuba kungekho inkinobho yokulungisa ngesandla, imoto ingalungisa ukuphakama kwesibani sekhanda ngokuzenzakalelayo ngokuya ngezinzwa ezifanele.
