Let's also examine the design, repair costs, and market prospects of vehicle repair companies. In reality, it's not easy to find such entities that are not worth a look. Key Point: Currently, domestic double-axle sprinkler trucks primarily focus on sales and repairs, as their manufacturing costs are relatively low, and so is their procurement cost.(1) To start the sprinkler truck operation, pull the handle of the four-way valve parallel to the ground, open the ball valve for the desired spray type (front spray, rear sprinkle, side spray, or rose spray), then start the engine, shift the transmission into gear, pull the take-up switch back to engage the gear and take power, then disengage the clutch, and the pump begins to operate, starting the sprinkling process. (2) Once the water in the tank is finished, the driver should promptly push the take-up lever forward to disengage the gear, stopping the operation of the sprinkler pump.
