Usage skills of aerosol spray

1. Correctly install the parts of the spray. Check whether there is air leakage at each connection. When using, install clean water for trial spraying first, and then install reagents.

2. When it is officially used, the agent shall be added first and then the water shall be added. The liquid level of the agent 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. Do not pull the rocker too hard to avoid explosion of the air chamber.

3. During the initial charging of the chemical solution, since the air chamber and spray rod contain clear water, the concentration of the chemical solution ejected in the first 2-3 minutes of spray is relatively low, so attention should be paid to supplementary spraying to avoid affecting the control effect of pests and diseases.

4. After the work is completed, the residual liquid medicine in the barrel shall be poured out in time, washed with clean water and drained. At the same time, check whether there is water in the air chamber. If there is water, remove the water connector to drain the water.

5. If the spray is not used for a short time, the main parts shall be cleaned, dried and installed, and stored in a cool and dry place. If it is not used for a long time, all metal parts shall be coated with butter to prevent rust.
