At the moment, there are a lot of green and foraging machines on the market. It can not only cut forage vines, high stalks, but also damage red peony and corn, and is commonly used in rural areas. The delay of the machine with the use of the time, often presents the following failures: work loss when broken; not start; undercharged electricity. Under normal circumstances can repair themselves.
First check the power outlet, plug, power cord, whether there is oxygen, fall off, broken place, if not, then you can plug in the power test machine, when the motor is not moving the bullet, hand lightly move the wheel and move the bullet, you can conclude It is caused by the missing capacity of one of the two startup capacitors of the aircraft. In this case, only new products are generally replaced. In addition, the situation is that when the power is applied to the projectile and the external force is applied to move the projectile, a weak current noise is generated in the motor. This is caused by the light leakage of the starting capacitor. If the electric current is loud, the motor cannot start, and it is determined that the starting capacitor is short-circuited. In the absence of a professional instrument, you can remove the capacitor, insert the two leads into the mains zero and front jacks to charge the capacitor, and then remove and short-circuit the two leads. If the discharge spark can be given at this time and there is a loud "click" sound, the capacitor can be used to declare the name; if the spark and the sound are weak, the capacity of the capacitor has dropped, and it needs to be replaced with a new one or a small capacitor. If the capacitor has been damaged short circuit can not use this method, and must use the same specifications of new products can be repaired.
