But how to maintain the sprinkler in the cold winter? Now let's summarize it for you.

The operator can pass the sight glass on the upper part of the rear head. When the liquid level reaches the middle part of the sight glass, the operator shall be informed. The colleague shall pull the water suction hose away from the water surface or close the four-way valve quickly. It is important to remember not to pay attention to the gesture made by the operator and blindly carry out the next operation.
2. Spray operation.
Open the ball valve to be sprayed (front flushing, rear flushing, side spraying and flower sprinkling), then start the engine, put the transmission into gear, pull the power take-off switch backward to shift the power take-off, then release the clutch, the pump starts to run, start sprinkling, open 7, 8, 9 and 10 as required, among which 7 is the front flushing switch, which is used to wash the road, 8 is the sprinkler switch (emergency fire fighting, remote control Distance watering flowers and trees). 9 is the side spray switch, which can water the flowers and trees on the roadside. 10 is the rear sprinkler switch, which is used to spray water on the road.
Before winter, the water in the water pump and water pipe of the sprinkler shall be emptied to prevent frost cracking. In northern China, construction will not be carried out in severe winter, so the water in the sprinkler pump and water pipe will be drained immediately after the construction to prevent future troubles.
