If corrosion is detected on the tank, first clean the corroded area of oil and impurities. Use a specialized grinding tool to remove the corrosion layer and inspect the depth of the corrosion. If the tank itself has not been damaged, apply an anti-corrosion coating for repair. If corrosion is severe or cracks have appeared, discontinue use and consult a professional to assess whether welding repairs or replacement of tank components are necessary. If the tank is deformed, first inspect the location and extent of the deformation. Minor deformation can be slowly restored using specialized correction tools to avoid forced correction that could cause cracking. Severe deformation requires replacement of the damaged section to ensure structural stability after repair.

If leakage occurs at a connection interface, first close the relevant valves to stop fluid flow. Disassemble the interface components and inspect the seals for aging and wear. If any problems are found, replace them promptly. When reinstalling, ensure component alignment and evenly tighten the bolts to prevent uneven force from affecting the seal. If loose traction connection components are found, stop the vehicle and take safety precautions. Use specialized tools to tighten loose bolts, traction pins, and other components. Check for proper clearance. If any components are worn, replace them promptly to ensure a secure and reliable connection.

If the liquid level sensor displays an abnormal reading, first disconnect the power supply, disassemble the sensor, clean any debris and oil from the surface, check for loose connections, reconnect the wiring, and test. If the sensor still does not function properly, replace it. If the oil pump or valve is operating poorly, first close the fluid flow path, disassemble the components, clean any obstructions, and inspect internal components for wear and seizure. Replace any damaged parts and reassemble. After reassembly, test the operation to ensure smooth fluid flow.

If a tire problem occurs, first park the trailer tank steadily and check the tire pressure. Refill or release the air to the standard pressure. If the tire is excessively worn or damaged, replace it with a new tire to ensure even load distribution. If the suspension system vibrates violently, check the springs, shock absorbers, and other components for wear and tear. Replace any damaged components and adjust the suspension clearance to the proper level. If the brake system malfunctions, check the brake lines for leaks and brake pad wear. Repair any leaks, replace any worn brake pads, and test the braking to ensure sensitive and reliable braking.
