What are the precautions for using the sprayer?

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

(2) The medicine can of the knapsack sprayer should not be overfilled, so as to avoid the mouth of the medicine can overflowing and splashing 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.

(3) When applying the medicine, the operator should stand in the upwind direction, pay attention to the change of the wind direction at any time, change the way of walking in time, and try to apply the medicine alternately in the same direction.

⑷ 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.

⑸ In order to ensure no failure during use and prolong the service life of the sprayer, after each use, the residual liquid in the barrel should be poured out in time, rinsed with water and drained.
