1. Install agricultural mist sprayer parts correctly. Check whether each connection is leaking. When using, 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, move the rocker more than 10 times to increase the air pressure in the barrel to the working pressure. Do not use excessive force when pulling the joystick to avoid an explosion of the air chamber.
3. When the chemical liquid is first filled since the air chamber and the spray bar contain clear water, the concentration of the chemical liquid sprayed in the first 2 to 3 minutes of spraying is low, so pay attention to the supplementary spray to avoid affecting the control effect of pests.
4. After the work is completed, you should pour out the remaining liquid medicine in the bucket in time, wash it with clean water and pour it out. At the same time, check whether there is water in the air chamber. If there is water, remove the water connector to release the water.
5. If the agricultural mist sprayer is not used in the short term, the main parts should be cleaned, wiped dry, and stored in a cool and dry place. If it is not used for a long time, grease all metal parts to prevent rust.
Common faults and troubleshooting methods
Insufficient spray pressure and poor atomization: If the water inlet ball valve is set up by dirt, you can remove the water inlet valve and clean the dirt with a cloth; if the cup is damaged, you can replace it with a new one; if the connection part is not installed The sealing ring or the air leakage due to the damage of 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, 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 gasket on the switch core is worn out, the gasket should be replaced; the switch cannot be screwed because it has been placed for a long time or used 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. Do not hit with hard objects.
Water leakage in each connection part: if the joint is loose, the nut should be tightened; if the washer is not flat or damaged, the washer should be flat or replaced; if the washer shrinks and hardens, it can be soaked in animal oil before use.
