Popanga njerwa, kuchuluka kwa njerwa zopanda pake kumakhala kwakukulu kwambiri, zowonadi, kuchuluka kwa makina opangira njerwa ndikokulirapo. Ndipo ku zipangizo ntchito angazindikirenso kuti ndi dzenje njerwa makina luso angapereke chitetezo, kotero zipangizo wonse akhoza kukhala bwino ntchito boma. Chifukwa chake ndikuyembekeza kuti anthu amvetsetsa zomwe zili m'gawo lililonse momveka bwino, ndipo pamapeto pake apeza yankho loyenera.

Pomvetsetsa luso la makina opangira njerwa, kukhazikika kwa zida zonse kumapangitsa kuti magwiridwe antchito azikhala bwino, kotero kuti ogwira ntchito omwe amafunikira pakugwirira ntchito zida akhoza kupulumutsidwa. Tikalabadira vuto la kugawa nsalu, timatengera ntchito ya kasinthasintha wapadera ndi mokakamiza kudula chipangizo galimoto hopper, kotero ife tikhoza kukwaniritsa bwino nsalu kugawa zotsatira. Ndipo mu chisamaliro chaukadaulo wa nsalu, chakudya chachiwiri chimakhalanso chosavuta kugwiritsa ntchito, mbali iyi ndi yabwino kwambiri.

Kumene, abwenzi ambiri angaganize kuti dzenje njerwa makina ndi kubala njerwa dzenje, koma mu ndondomeko yeniyeni kupanga zinthu njerwa, akhoza kutulutsanso njerwa perforated, njerwa msewu ndi mitundu ina ya mankhwala, kotero makina wapanga yojambula luso, ndipo akhoza kupanga mitundu yambiri ya mankhwala. Makamaka, ntchito yodzitsekera yokha ya makina opangira makina ndi yofunika kwambiri, yomwe imapangitsa kuti chitetezo cha ntchitoyo chikhale bwino kuchokera kuzinthu zamakono.

Choncho, pomvetsetsa luso la makina a njerwa, ichi ndi chinthu chomwe chingathe kukwaniritsa bwino kupanga gawo lililonse. Pomvetsetsa mtundu uwu wa mankhwala, ndikofunikanso kwambiri kuti muthe kumvetsa gawo lililonse. Ndi njira iyi yokha yomwe tingathe potsiriza kupeza yankho loyenera kwambiri pakupanga.
