2. Musanagwiritse ntchito, zigawo ziwirizi ziyenera kugwedezeka bwino komanso mofanana. Osasiya malo aliwonse osasakaniza; apo ayi, zomatira sizingachiritse.

3. Magawo amayenera kutsukidwa bwino ndipo asakhale ndi chinyezi (pokhapokha ngati zomatirazo zidapangidwira kuchiritsa pansi pamadzi).

4. Kuti tipeze mphamvu zomangirirana kwambiri, magawowo ayenera kudulidwa (mchenga) momwe angathere.

5. Mapangidwe a mgwirizano wogwirizana amakhudza mwachindunji mphamvu yomaliza ya mgwirizano.

6. Zomatira ziyenera kusakanikirana ndikugwiritsidwa ntchito nthawi yomweyo. Musayisiye itayima kwa nthawi yayitali mutasakaniza. Kwa mitundu yofulumira-yochiritsa, nthawi yogwira ntchito siyenera kupitilira mphindi ziwiri.

7. Ngati mukufuna mphamvu yochulukirapo komanso kuchiritsa mwachangu, kutenthetsa kutha kugwiritsidwa ntchito moyenera. Pogwiritsa ntchito zomatira, wosanjikiza sayenera kukhala wandiweyani; pafupifupi 0,5 mm akulimbikitsidwa. Zigawo zokhuthala kwenikweni zimachepetsa kugwirizana bwino.

8. Panthawi yolumikizana, ndi bwino kukakamiza kapena kulimbitsa ziwalozo ndi zingwe.

9. Kuti mukhale ndi mphamvu zambiri, lolani msonkhano womangika kuti upumule kwa maola osachepera 24 mutatha kugwirizana.

10. Kwa chimodzi-chinthu chosungunulira-chotengera kapena madzi-zomatira, nthawi zonse yambitsani bwino musanagwiritse ntchito.
