How to adjust and control the spray range and angle?Answer: We pull the automatic return control loopoutwards and upwards. At this time, the nozzle will rotate 360 degreesunder the force of water.To control the size of the sprayed vegetation area, as long as the automatic return control loopis dialed down, the angle of the U-shaped stainless steel limit loopcan be adjusted to adjust the spraying range of the desired spray head.After the sprinkler nozzleis adjusted at a controlled angle, the sprinkler nozzle oscillates back and forth under the force of the gravity rocker arm and stainless steel spring under the impact of water, forming a back and forth knock, resulting in workmanship.In the nozzle operation, after automatically rotating to the adjusted control angle point, the reversing lever and the returning control lever meet the limit loop, and then quickly rotate back under the vibration of the rocker arm. This is how the nozzle works back and forth.2.
