1, mphamvu yowumitsa, chifukwa cha zinthu zomwazika kwambiri mumtsinje wamlengalenga, gawo lonse la particles ndi louma kwambiri komanso lothandiza.

2, nthawi yochepa yowumitsa

3, chowumitsira mpweya ndi chosavuta, chopondapo chaching'ono, chosavuta kumanga ndi kukonza.

4, mphamvu yayikulu, yotentha kwambiri.Kutentha kwabwino mpaka 60% mukaumitsa madzi osamangika.

5, chowumitsira kuti mukwaniritse "zero horizontal thrust", kuchepetsa kwambiri kuwonongeka ndi kung'ambika kwa gudumu losunga, silinda ikuyenda bwino komanso modalirika;

6, chowumitsira chimagwiritsa ntchito "chipangizo chodzigudubuza chokha", kotero kuti chodzigudubuza chothandizira ndi mphete yodzigudubuza nthawi zonse imakhala yolumikizana, motero kuchepetsa kwambiri kuwonongeka ndi kuwonongeka kwa mphamvu.

7, chowumitsira bokosi chomwe chimasinthidwa kukhala pepala lopumira, mizere, kuumitsa zinthu za granular.Pakuti zofunika otsika kuyanika kutentha, yaitali kuyanika nthawi ya zinthu wapadera ubwino.
