Kupanga zida zamakina a njerwa kumafuna mgwirizano wogwirizana wa ogwira ntchito. Zowopsa zachitetezo zikapezeka, ziyenera kuzindikirika ndikufotokozedwa mwachangu, ndipo njira zogwirizira ziyenera kuchitidwa munthawi yake. Mfundo zotsatirazi ziyenera kuzindikirika:

Kaya matanki amadzimadzi osiyanasiyana amphamvu kapena anti-corrosion liquids monga petulo ndi mafuta a hydraulic a zida zamakina a njerwa achita dzimbiri komanso kuwononga; Kaya mapaipi amadzi, ma hydraulic mapaipi, mapaipi oyendetsa mpweya ndi mapaipi ena athyoka kapena kutsekedwa; Onani ngati pali kutayikira kwamafuta mu gawo lililonse la tanki yamafuta; Kaya zolumikizira zolumikizana za chipangizo chilichonse ndizotayirira; Kaya mafuta opaka m'zigawo zogwira ntchito za chipangizo chilichonse chopangira ndi chokwanira; Lembani nthawi yogwiritsira ntchito ndi kuchuluka kwa nkhungu, ndikuyang'ana mapindidwe;

Kaya makina osindikizira a hydraulic, controller, dosing zida ndi zida zina zamakina a njerwa ndizabwinobwino; Kodi pali zinyalala zilizonse zomwe zasonkhanitsidwa pamzere wopanga ndi malo; Kaya zomangira za nangula za wolandirayo ndi zida zothandizira ndizolimba; Kaya kuyatsa kwa zida zamagalimoto ndizabwinobwino; Kaya zizindikiro zochenjeza za dipatimenti iliyonse pamalo opangira zinthu zimakhala zomveka; Kaya malo otetezera chitetezo cha zida zopangira ndi zachilendo; Kodi malo oteteza moto pamalo opangira njerwa amamveka bwino komanso abwinobwino.
