1.When using rivers or ponds as water sources, ensure the end of the suction pipe is fully submerged. To avoid sucking in stones, heavy sediment, or floating debris, a filter is usually fitted to the pipe end—never remove this filter while drawing water. If the water source is shallow, dig deeper in the suction area to keep out debris and air. Different sprinkler pumps have different water requirements: clean-water pumps need impurity-free water, while muddy-water pumps can handle some sediment but no stones.

2.Before each use, centrifugal water pumps need to be primed with water, and the inlet must be closed afterward. Self-priming pumps only need priming the first time they’re used.

3.The inlet pipe system must maintain a vacuum to draw water into the tank. Ensure the system is tightly sealed: hoses should be undamaged, and hard pipes free of cracks—any leaks will let in air and prevent water from being drawn.

4.Always shift the power take-off when the vehicle is stationary, whether before drawing water or sprinkling.

5.Drain all water from the pump and pipes before winter to prevent freezing damage.

6.Front sprinklers are low to the ground with high pressure, ideal for road flushing; rear sprinklers (usually one on each side) are higher and cover more area, suitable for road maintenance. Close front sprinklers when using rear ones. Adjustable nozzles let you control sprinkling width—the wider the coverage, the less overlap, and the more even the distribution.

7.Regularly lubricate moving parts and tighten connections during use to keep the truck running smoothly.

8.Sprinklers have a drain pipe at the tank’s lowest point. Periodically open this to flush out accumulated debris until the water runs clear.
