You should check whether each connection is leaking. When using, you'd better install clean water and test spray first, and then install the medicine.
2. In formal use, you must add the medicine first and then water, and the liquid level of the medicine should not exceed the safe water level. Before spraying, you can move the rocker more than 10 times to increase the air pressure in the barrel to the working pressure. You'd better not use excessive force when turning the joystick to avoid explosion of the air chamber.
3. When the chemical liquid of backpack sprayer is first filled, since the air chamber and the spray bar contain clear water, the concentration of the chemical liquid sprayed during the first 2 to 3 minutes of spraying is low, so you ought to pay attention to the supplementary spray to avoid affecting the control effect of pests.

Common faults and troubleshooting methods of backpack sprayer

When the pressure of a backpack sprayer is insufficient, the atomization is poor. If the water inlet ball valve is set up by dirt, the water inlet valve can be removed and the dirt can be removed with a cloth. If the cup is damaged, a new cup can be replaced. If the connection part is not equipped with a sealing ring or the sealing ring is damaged. For air leakage, the sealing ring can be installed or replaced. 
No fogging: If the oblique hole of the nozzle body is blocked by dirt, the oblique hole can be cleared. If the nozzle is blocked, the nozzle can be removed and cleaned, but hard objects such as iron wire or copper needle can not be used to poke the nozzle to prevent the hole from expanding, you should make the spray quality worse. If the filter screen in the casing is blocked or the water valve ball is set up, the filter screen and the dirt that set up the ball should be cleaned.
The switch leaks or cannot be screwed. If the switch cap is not tightened, the switch cap should be tightened. If the washer on the switch core is worn out, the washer should be replaced. The switch cannot be screwed because it has been placed for a long time or used for a long time. The core is stuck due to the corrosion of the agent, the parts should be removed and cleaned in kerosene or diesel. If it is difficult to remove it, it can be soaked in kerosene for a period of time, and then it can be removed after disassembly. You'd better not hit with hard objects.
Water leakage in each connection: if the joint is loose, the nut should be tightened. If the washer is not flat or damaged, the washer should be leveled or replaced; if the washer shrinks and hardens, it can be soaked in animal oil before use .
