Uchungechunge lwe-SL wuhlobo olusha lwemishini yokwelapha yomthombo womoya womoya, okuhlanganisa isihlungi somthombo womoya, Isilawuli Sokucindezela kanye nesigcobo.
Isihlungi somthombo womoya sisetshenziselwa ukuhlunga ukungcola nezinhlayiya ezisemoyeni, ukuqinisekisa ikhwalithi yomoya enhle engena ohlelweni. Isebenzisa izinto zokuhlunga ezisezingeni eliphezulu, ezingasusa ngempumelelo uthuli, umswakama, namafutha emoyeni, ivikele ukusebenza okuvamile kwemishini elandelayo.
I-Pressure regulator isetshenziselwa ukulawula umfutho womoya ongena ohlelweni ukuze kuqinisekiswe ukusebenza okuzinzile kwesistimu. Inobubanzi obunembile bokulawula i-voltage nokunemba, okungalungiswa kuye ngokwezidingo, futhi inesivinini esihle sokuphendula nokuzinza.
I-lubricator isetshenziselwa ukuhlinzeka ngamafutha okugcoba emishinini ye-pneumatic ohlelweni, ukunciphisa ukungqubuzana nokuguga, nokwelula impilo yesevisi yemishini. Yamukela izinto zokuthambisa ezisebenzayo kanye nomklamo, onganikeza umphumela ozinzile wokugcoba futhi unesakhiwo okulula ukusinakekela nokusishintsha.
