How to adjust and control the spray range and angle?Answer: We pull the automatic return control loop outwards and upwards. At this time, the nozzle will rotate 360 degrees under the force of water.To control the size of the sprayed vegetation area, as long as the automatic return control loop is dialed down, the angle of the U-shaped stainless steel limit loop can be adjusted to adjust the spraying range of the desired spray head.After the sprinkler nozzle is 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. How to adjust the distance of the water to be sprayed farther and closer, and spread it out?Answer: As long as we turn the water stopper up or down, we can cover the nozzle of the sprayed water, so that the water can be sprayed closer.To let the water spray out, we need to turn the stainless steel adjustment screw clockwise or counterclockwise to turn the adjustment screw to disperse a stream of water.
