Precautions before using a Hand sprayer
When using different hand sprayers, we must read the user manual in detail, and strictly abide by the usage rules and maintenance methods of each Hand sprayer to prevent damage to the parts or weaken the strength of the instrument. Before using the hand sprayer daily, make sure that there is no pressure in the tank, otherwise, you need to decompress it first. When it is officially used, it is necessary to add the medicine first and then add water, and the liquid level of the medicine cannot exceed the safe water level. Before spraying, turn the rocker more than 10 times to increase the air pressure in the barrel to the working pressure. The pressurization step can only be operated by hand, and no mechanical device can be used. When using the Hand sprayer, don't use too much force when pulling the rocker to prevent the air chamber from exploding. If the tank is found to be damaged, rusted, or corroded, or the hose is loose or damaged, do not perform the pressurization step. If the accessories are found to be discolored or overheated, they should be replaced in time.
Precautions during the use of a Hand sprayer
When the chemical solution is charged for the first time, due to the clear water in the air chamber and the boom, the concentration of the chemical solution sprayed out how to spray 2 to 3 minutes before spraying, attention should be paid to supplementary spraying, so as not to affect the effect of pest control. It should be noted that the Hand sprayer cannot hold or use corrosive items such as strong alkalis or strong acids, and cannot hold hot liquids. After the work is completed, the residual liquid in the barrel should be poured out in time, rinsed with clean water, and wiped dry, especially the throat and medicine tank. Also, check for water in the gas chamber. If there is water, remove the water connector and drain the water. If the Hand sprayer will not be used for a short period, the main parts should be cleaned, dried and installed, and stored in a cool and dry place. All metal parts should be greased to prevent rusting if not used for a long time.
