1. Ar dtús, seiceáil an soicéad cumhachta, an breiseán, agus an téad cumhachta le haghaidh doirteadh agus briseadh ocsaigine. Mura bhfuil, plug isteach an soláthar cumhachta chun an meaisín a thástáil.
2. Nuair nach rothlaíonn mótair an pulverizer fíneáil tar éis an chumhacht, ach is féidir an roth a rothlú go héadrom de láimh, is féidir a thabhairt i gcrích go bhfuil ceann amháin den dá toilleoirí tosaigh den theipeann ar an meaisín. Sa chás seo, de ghnáth ní chuirtear in ionad é ach ceann nua.
3. Another situation is that it does not rotate when powered on, but can rotate when external force is applied, but there is a weak current sound in the motor, which is caused by a slight leakage of the starting capacitor. If the current is too loud, the motor cannot be started at all, and it is concluded that the starting capacitor is short-circuited. In the absence of professional equipment, the capacitor can be removed first, and the two leads are inserted into the zero and live wire jacks of the mains to charge the capacitor, and then the two leads are short-circuited and discharged. If there is a discharge spark and a loud "pop" sound at this time, it means that the capacitor can be used; if the spark and the sound are weak, it means that the capacity of the capacitor has decreased, and it needs to be replaced or a small capacitor is added. If the capacitor has been damaged and short-circuited, this method cannot be used, and it must be replaced with a new product of the same specification to repair.
