Normal use and maintenance of mist sprayer

Mist sprayer has the advantages of high efficiency and good control effect. However, due to the use of mist sprayer spraying water consumption is small, high concentration of liquid medicine, machine around the formation of high concentration, very small particles of fog, if improper operation, often more likely to cause operator poisoning, or local uneven application of drugs, resulting in poor control effect. At the same time, the correct maintenance of mist sprayer is an important measure to improve its technical performance and operation quality, and prolong its service life. Therefore, in order to enable the majority of rice growers to better grasp the correct use and maintenance of mist sprayer, to ensure timely and effective control of rice blast and other diseases and insect pests, mist sprayer’s correct use and maintenance methods are introduced as follows:
1. Assemble the machine according to the instructions, and check the correct position of the parts, fasten the bolts, keep the air passage unobstructed, flexible running parts, and intact protective cover. To talk about
2. Add lubricating oil to the crankcase according to the label specified in the instructions to the prescribed oil level, and check before each use, and check and add lubricating oil to the gasoline engine according to the regulations. To talk about
