First of all, when using it for the first time, check the connection for leaks. When using, first fill with water to test spray, and then fill with medicine. When adding the medicine, add the medicine first and then add the water, so the liquid level of the medicine liquid cannot exceed the safe water level. Before spraying, start the electric sprayer to make the atmospheric pressure in the barrel reach the working pressure to ensure smooth spraying.

Secondly, after connecting the sprayer and the power pump, first clean the sprayer's liquid tank, hose, boom and other components, paying special attention to removing the grease on the pump, so as to remove the mud at the bottom of the liquid tank. Since most pesticides have a special corrosive effect on the sprayer, it should be rinsed with alkaline water in time after stopping the drug, and then rinsed with clean water. Especially after spraying corrosive pesticides such as Bordeaux mixture, it is best to soak in alkaline water for 1-2 hours. Take care to prevent rust. All parts to be dismantled must be removed and cleaned. The inner pipe wall of the boom and nozzle should be coated with oil to prevent moisture and rust.

Finally, the heart of an electric sprayer is the pump, and therefore the battery. While there are several types of pumps on the market, these are all afraid of clogging. Therefore, clean water must be used to organize the medicine. When adding water, it must be filtered with a little filter to avoid clogging.
