Hazard

In the assembly process of the steering cylinder, the hydraulic hose attachment position is improper. When the tires are tilted (leaning state) and the steering is turned sharply, the hydraulic hose may interfere with the leaning rod. Continued use in this condition can damage the hose, and in the worst case, the hose may rupture, causing hydraulic fluid leakage and resulting in loss of steering control.
