1. To install the 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 turning the joystick to avoid 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 during 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 and diseases.
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.
5. If the sprayer is not used for a short period of time, the main parts should be cleaned, wiped dry and installed, 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 in use:
Insufficient spray pressure and poor atomization: If the water inlet ball valve is set up by dirt, the 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 installed The sealing ring, or the air leakage due to 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 needles should 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, the gasket should be replaced; the switch cannot be screwed because it has been placed for a long time or used for a long time, the switch 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 at 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 .
