440C insimbi engagqwali yensimbi engenasicingumkhiqizo wensimbi osezingeni eliphakeme owaziwa ngenhlanganisela yayo ehlukile yokumelana nokuqina kokugqwala. Kungokomndeni wensimbi engenacala futhi kusetshenziswa kabanzi kwizimboni ezahlukahlukene ngokusebenza kwayo okuphezulu.
Izinga lensimbi engu-440C insimbi engagqwali namabanga afanayo ensimbi

3. Ukumelana nokugqwala: yize kwakuyinsimbi enamandla amakhulu, ama-440c akhombisa ukumelana okuhle kokugqwala.
I-4. Ubulukhuni kanye namandla: 440c Insimbi Engagqwali I-Bar Bar inobunzima obuhle namandla aphezulu, ukuhlinzeka ngokuqina nokuphila isikhathi eside ezisetshenziselwa izicelo.
