How to operate the sprayer safely? Posted by : admin / Posted on : Dec 02,2021

1. The user must undergo rigorous training. When using the sprayer for the first time, the paddy field sprayer must be familiar with the operation and maintenance instruction manual to figure out the performance of the machine and the precautions for use.

2. The operator should wear long clothes, trousers, boots, and wear masks, gloves, and protective glasses when spraying drugs to prevent poisoning.

3. Clean up and inspect the sprayer. Clean the medicine barrel to avoid unnecessary losses caused by the medicine left over from the last spray. Check the oil level position of the engine, and the professional paddy field sprayer should not be lower than the standard scale, and the color is normal and the viscosity is appropriate. Check the lubricating oil level of the high-pressure pump, and it cannot be lower than the scale line. Check whether the gasoline is sufficient and the air filter is clean. Whether the various fixing screws are tightened, whether the length of the high-pressure pipe is sufficient, and whether there is any damage.

4. Before starting, the operator closes the water outlet valve, opens the unloading handle to make it in a pressure relief state, and adjusts the pressure of the high-pressure pump to a lower level. To start the engine in a cold state, first close the throttle, open the throttle to the starting position or higher, and then open the throttle at an appropriate time after starting. When the engine is warming up, the damper can be opened to start.

5. Open the water outlet valve, adjust the high pressure pump to the required pressure, and spray at a constant speed. The continuous working time of the sprayer should not exceed 4h.
