Pay attention to the use of knapsack sprayers

2. When using it formally, add the medicine first and then add the water. The liquid level of the medicine should not exceed the safe water level. Before spraying, turn the rocker more than 10 times to make the air pressure in the barrel rise to the working pressure. Do not use too much force when pulling the rocker to prevent the air chamber from exploding.

3. When the chemical solution is first loaded, since the air chamber and the spray rod contain clean water, the concentration of the chemical solution sprayed out in the first 2 to 3 minutes of spraying is low, so attention should be paid to supplementary spraying, so as not to affect the control effect of pests and diseases.

4. After the work is completed, the residual liquid medicine in the barrel should be poured out in time, washed with clean water and dried. At the same time, check whether there is water in the gas chamber. If there is water, remove the water joint to release the water.

5. If the sprayer will not be used in a short period of time, the main parts should 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 should be coated with butter to prevent rust.
