3. Tsegulani botolo la nayitrogeni, tembenuzirani valavu yowongolera pang'onopangani kuthamanga kwa gauge kufika pamtengo wofunikira, ndi mpweya wa nayitrogeni uyenera kutayidwa kuchokera kumapeto kwa chubu choyenga.
4. Yatsani mphamvu, kuwala kofiira ndipamwamba.Kanikizani chosinthira, kuwala kobiriwira kumayaka, ndipo choyengacho chiyenera kupopera kuchokera kumapeto kwa chubu choyenga.
5. Ikani chubu choyenga mu dziwe losungunuka la aluminiyamu, ndi potulutsira chubu choyengachimayenda mmbuyo ndi mtsogolo motsatira pansiwa ng'anjo mpaka woyengayo atayidwa.
6. Pitirizani kudutsa nayitrogeni kwa mphindi 1-2, kenako chotsani chubu choyenga ndikusiya kupereka nayitrogeni.
Kusamalitsa

3. Panthawi yosungira ndikugwiritsa ntchito,kuletsa mosamalitsa chubu choyenga kuti chisapindike, zomwe zingayambitse kutsekeka.
4. Panthawi yoyenga,kuletsa mosamalitsa kutuluka kwa chubu choyenga kuti zisagwirizane ndi ng'anjo pansi ndi khoma la ng'anjo.Ngati kukhudzana kumachitika, kungayambitse kutsekeka mosavuta.
5. Pamene wothandizira woyenga ali wonyowa, zimakhala zosavuta kuyambitsa kutsekeka.Pakadali pano,choyengacho chiyenera kuuma ndi kusefa musanagwiritse ntchito.
6. Pamene pali aluminiyamu yotsalira ndi zotsalira mu chubu choyenga, ziyenera kutsukidwa kuti zitsimikizire kuyenda bwino kwa chubu choyenga.
