Here is the content list:
Preparation of Manual sprayer
Correctly install the components of the Manual sprayer before use. Check each connection for air leakage. When using, test sprays with water first, and then refill the medicine. Before the operation, prepare pesticides according to the operating procedures and strictly abide by the use of medicines. Before filling the liquid medicine tank, the switch must be turned off to avoid leakage of the liquid medicine. The liquid medicine should be filtered by a filter screen, and the liquid level of the liquid medicine liquid should not exceed the safe water level. Then put the Manual sprayer behind your back, hold the pressure rod in your left hand, and press it up and down to certain pressure (the number of pressings is about 30 times/min), hold the spray rod handle in your right hand to turn on the switch and swing the spray rod, according to the plants being sprayed (or area) adjust the size of the switch, so that the nozzle can be sprayed up and down or left and right as needed.
How to use a Manual sprayer
When the chemical solution is first loaded since the air chamber and the boom contains clear water, the concentration of the chemical solution sprayed out in the first 2 to 3 minutes is low, pay attention to supplementary spraying, so as not to affect the control effect of diseases and insect pests. When using the Manual sprayer, you should concentrate, cooperate with your hands and eyes, use force and rhythm, and aim the nozzle at the plant parts affected by diseases and insect pests to spray pesticides, to be thoughtful, uniform, correct and safe. After the work is completed, the residual liquid in the barrel should be poured out in time, rinsed with clean water, and dried. Also, check the air chamber for water. If the Manual sprayer is not to 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. Within 48 hours after the drug is used, if phytotoxicity is found, the washing powder solution of 1%~2% of the alcohol should be sprayed immediately, or the alcohol and Water should be sprayed several times to reduce phytotoxicity and loss.
