When there is a problem with the steering system, you need to conduct a preliminary inspection. You must first understand the situation. Don't rush to remove the steering gear. It should be a component that needs to be checked later. In the steering system, there are many other components. Cause a malfunction, so check other parts first.   First, check the steering wheel and tires of the electric forklift. When the steering gear is disengaged, whether the steering wheel and wheels rotate flexibly and without resistance, whether the tire size is appropriate, and whether there is damage. Then check the installation angle of the steering wheel of the electric forklift, that is, the front wheel positioning angle, check whether the tie rod system is abnormally loose or tight, and then check the ball joint and king pin. The next step is to check other places that have been replaced before, such as repairing the replaced tubing, whether the direction of the tubing is wrong, or whether the diameter of the replaced tubing is too small, and other restrictive factors. If this happens, you need to rearrange the twisted and bent tubing and replace the tubing that is different from the original state. The last step is to check the oil storage tank of the power steering of the small electric forklift to ensure that the oil reaches the correct level, check the transmission belt of the pump, and adjust the belt according to the parameter requirements.
