Full Repair of Ignition System of Dongfanghong-18 Motorized Mist Duster (1)
The Dongfanghong-18 Knapsack Duster has a wide range of uses and is used more and more in domestic plant protection machinery. It can be used for misting, dusting, and ultra-low-volume operations on plants. Power uses 1E40F or 1E40FP gasoline engine. In addition to plant protection machinery, the 1E40F gasoline engine can also be used as a power for small harvesters, threshers, and lawn mowers. The ignition system in the IE40F gasoline engine is composed of a magneto motor connected to the spark plug through a high-voltage wire, and the ignition system is an important part of the 1E40F gasoline engine. The following is a breakdown of the ignition system (CL-2) magneto system during the use of the machine. Maintenance method for reference. 1, check the integrity of the spark plug to remove the spark plug from the body, with a thick gauge to check the gap between the center electrode and the measuring electrode, 0.6-0.7 mm is normal, otherwise it is necessary to restore. Too much coke to clear. In the outside of the body, connect high-voltage lines, iron with the body, pay attention to close the carburetor, pull the rope to turn the gasoline engine. If there is a blue-white spark, it means normal, there is no spark, change a new spark plug, turn the gasoline engine again, if there is spark, it means the original spark plug is damaged; if the new spark plug still has no spark, it means there is a fault inside the magneto. 2. Check that the capacitor turns the gasoline engine and observe the spark plug's flashover condition. Then, remove the original capacitor and replace it with a new one. If you turn the gasoline engine again, if the spark of the new capacitor is normal and the spark of the old capacitor is weak or no spark, the old capacitor is damaged.
