1 转向沉重t（1）若快转及慢转方向盘均沉重，并且转向无压力，则可能是油箱液面低，油液粘度太大，或阀体内单向阀失效造成的。首先检查液压油箱油位及液压油的粘度。如果油位低于标准高度，则要添加液压油；油液粘度太大，则应更换粘度合适的液压油。如果油位、粘度正常，则
1 Steering heavily (1) If the steering wheel is both heavy and slow, and the steering is non-stressed, it may be caused by low fuel level, too much oil viscosity, or failure of the check valve in the valve body. First check the hydraulic tank oil level and the viscosity of hydraulic oil. If the oil level is below the standard height, then add hydraulic oil; oil viscosity is too large, you should replace the appropriate viscosity of the hydraulic oil. If the oil level, the viscosity is normal, then
