Momwe mungagwiritsire ntchito makina a njerwa osawotchedwa molondola wakhala vuto kwa makampani ambiri. Pokhapokha atagwiritsidwa ntchito moyenera angatsimikizire chitetezo chopanga. Kugwedezeka kwa makina a njerwa osawotchedwa ndi achiwawa, zomwe zimakhala zosavuta kuyambitsa ngozi monga flywheel friction lamba kugwa, zomangira zomangira, mutu wa nyundo kugwa mwachilendo, ndi zina zotero.

(1) Samalani ndi kukonza. Kuchuluka kwa ntchito ndi nthawi yogwira ntchito ya makina a njerwa osawotchedwa ndi ofanana ndi makina ena, zomwe zimadalira kusamalidwa bwino kwa zigawo zikuluzikulu. Tiyenera kudikirira pafupipafupi kuti tiwone makina osindikizira. Kwa mtundu watsopano wosindikizira njerwa, makina osindikizira a njerwa zamtundu ndi makina osindikizira a njerwa za hydraulic, tiyenera kusamala kuti tiwone kachulukidwe. Pakhoza kukhala mavuto ambiri ang'onoang'ono kumayambiriro kwa ntchito, choncho sitiyenera kukhala osasamala. Pambuyo pakugwiritsa ntchito kwa nthawi yayitali, kuchuluka kwa zowunikira kumatha kuchepetsedwa moyenera, koma kuwunika pafupipafupi kumafunika. Kwa makina omwe ali ndi mphamvu yogwira ntchito kwambiri, yang'anani pafupipafupi.

(2) pofuna kuonetsetsa kuti makina akugwiritsidwa ntchito moyenera, nthawi yomanga sidzachedwa. Akumbutseni ogwira ntchito kuti asunge zida zosinthira zomwe ndizosavuta kuvala mukamagwiritsa ntchito mosungiramo zinthu. Mbali zomwe zimawonongeka nthawi zambiri zimakhala ntchito yolemetsa. Wogwiritsa ntchitoyo ayenera kuyang'aniridwa mosamala panthawi yogwiritsira ntchito, ndipo zolakwika zidzapezeka panthawi yake kuti zitsimikizidwe kuti zikugwira ntchito motetezeka.

(3) Musanagwiritse ntchito makina a njerwa osawotchedwa, ayenera kufufuzidwa mosamala musanagwiritse ntchito. Ndikoletsedwa kwa ogwira ntchito omwe si akatswiri kugwiritsa ntchito zidazo, kulabadira kachitidwe kantchito ndikusintha kachitidwe.
