MATTERS NEED ATTENTION FOR FC-30 OIL FILTER USING

Every time after using the oil filter, Please do not forget to drain the residual oil inside of the oil pump, most of the oil would get solid after the temperature down(in the cold weather place,this happens all the time), if there is resdual oil in the pump, it will stop the pump running when you use it next time, and the pump motor would get burnt if it can not run.
