There are a lot of green feed mills on the market today. It can not only cut forage vines and tall stalks, but also can smash red leeks and corn. It is commonly used in rural areas. With the extension of the use of the machine, often appear: work can not be crushed; do not start, power and other failures. Under normal circumstances can repair themselves. First, check whether the power outlet, plug, and power cord have any oxygen evolution or breakage. If not, plug in the power supply tester. When the motor is turned on without turning the motor, the light-toggle wheel can be turned by hand. One of the two startup capacitors of the aircraft is due to a capacity failure. In this case, generally only for new products. The other case is that the power is not rotating, and the application of external force can rotate but the motor emits a weak current noise, which is caused by the slight leakage of the starting capacitor. If the current noise is too large, the motor cannot be started at all and it is determined that the starting capacitor is short-circuited (the motor coil is short-circuited and requires professional repair). In the absence of professional equipment, you can remove the capacitor (4UF/400V), insert the two leads into the neutral wire and the hot wire jack of the power supply respectively to charge the capacitor, and then remove and short-circuit the two leads. If the discharge spark can be issued at this time and there is a loud "click" sound, indicating that the capacitor can be used; if the spark and the sound is weak, indicating that the capacity of the capacitor has decreased, need to be replaced or added a small capacitor. If the capacitor has been damaged short circuit can not use this method, and must be replaced with new products with the same specifications can be repaired.
