Found in the maintenance, the machine in a lot of electrolytic capacitor (the capacity of 0.47 u F ~ 100 u F, compression value of 25 v ~ 50 v) are oil immerse around and around, it's clearly a electrolytic capacitor leakage caused by. According to the original nominal value quality of imported capacitance change all new, all failure one-time elimination.4cWservice manual download site
