Poyerekeza ndi mutu wamba wotopetsa, mtundu watsopanowu uli ndi zotsatirazi:
1, Chitsogozo chodzigudubuza, chothandizidwa ndi mfundo zambiri komanso kalozera wokhazikika.
2,Kulumikizana kwa mfundo pakati pa wodzigudubuza ndi khoma lamkati la chogwirira ntchito kumachepetsa kukangana ndikutalikitsa moyo wogwiritsa ntchito;koposa zonse, zimapewa vuto losintha pafupipafupi pad yowongolera.
3, zokolola zitha kuonjezedwa pawiri.
4, Kukula kungasinthidwe mumtundu wa 5 mm, sikufuna kusintha magawo aliwonse, kotero kuti ntchitoyi ndi yabwino kwambiri komanso yopulumutsa nthawi.
Wodzigudubuza amatenga muyezo wadziko lonse, ndizosavuta kupeza pamtengo wokwanira pamsika, kugwiritsa ntchito ndalama kumakhala kotsika.
Mtundu watsopano wotopetsa mutu umayesedwa mobwerezabwereza, umakhala ndi ntchito yokhazikika ndipo umakhala ndi mbiri yabwino kuchokera kwa wogwiritsa ntchito.
