At present, the company's after-sales service is visiting new users in various places to understand the actual situation of using the new machine, and through the visits, some problems have been discovered.

1. Five control handles, one of which is directional and can control the rotation of the fertilizer spreader upwards or downwards. The operation should be carried out according to the label prompts. When not performing fertilizer spreading operations, the handle should be returned to the center position and should not be placed in the opposite position! Placing the handle in the "prohibited" position on the label can cause hydraulic system failure! Affects the lifespan of hydraulic pumps!

2. Users in Lianyungang have encountered the situation that the amount of spray becomes smaller after using it for a period of time. In fact, they ignored the influence of the filter system due to the long-term non cleaning of the suction screen of the drug pump and the mixing of impurities such as pesticide bags.

3. Within 50 hours, the engine oil and hydraulic oil should be replaced, and the hydraulic oil inlet filter should be cleaned! In the initial stage, there will be metal debris generated during running in and impurities generated during assembly and welding. The earlier the maintenance, the longer the service life of the machine can be extended.

4. The 3WP-800 machine medicine box filled with water can meet the demand for pesticide application on 40 acres of land. Excessive pressure on the distribution valve can lead to premature use of the medicine, resulting in excessive pesticide application! The normal working pressure of medication is 4-8BAR.
