1. Correctly install parts and components of the sprayer. Check whether there is air leakage in each connection. When using, install water to test spray first, and then load the reagent.
2. For official use, add the medicament first and then add water. The liquid level of the medicated liquid shall not exceed the safe water level. Before spraying, pull the rocker more than 10 times to make the air pressure in the barrel rise to the working pressure. The rocker should not be pulled too hard in case the air chamber explodes.
3. During the initial loading of liquid medicine, since the air chamber and spray rod contain clear water, the concentration of liquid medicine ejected in the first 2 to 3 minutes of the spray is relatively low, so attention should be paid to the spraying, so as not to affect the control effect of diseases and insect pests.
4. Upon completion of the work, the residual liquid medicine in the barrel should be poured out in time and dried with clean water. Meanwhile, check whether there is water in the air chamber.
5. If the sprayer is not used in a short time, the main parts should be cleaned, dried and installed, and stored in a cool and dry place. If not used for a long time, the metal parts should be coated with butter to prevent rust.
