In order to ensure no failure during use, prolong the life of the sprayer, and ensure the safety of the staff. Corresponding inspections must be carried out before and after the sprayer is used, and certain precautions must be observed in the process of spraying pesticides.

Before operation, check whether the parts of the sprayer are damaged, whether there is water leakage, and whether the spray is normal. First, test the spray with clean water.

When applying the medicine, the operator should stand on the windward position, pay attention to the change of the wind direction at any time, change the walking mode in time, and try to apply the medicine alternately.

The can of the knapsack sprayer should not be overfilled, so that the medicine does not overflow from the mouth of the can and splash on the applicator when bending over. The spraying time should also be selected correctly. Avoid spraying at noon when the sun is strong, because the pesticide volatilizes at this time, the operator sweats a lot, and the pesticide can easily penetrate into the human body through the pores.

Once the sprayer fails during the working process, it should stop working immediately, close the valve, and carry out inspection and repair. If the nebulizer line or liquid pump fails, the pressure in the line must be reduced first. When opening the compressed air chemical tank, the compressed air in the cylinder should be released first to avoid accidents.
