Q Lift cylinder piston rod to shake during the lifting process
A
The problem should be judged that the hydraulic oil in the mailbox is not perfect, resulting in the liquid pump pressure problem. Then you need to identify the air from the hydraulic line to the cylinder piston section. The main solution to solve the problem is to increase the hydraulic oil, if it can not work normally, it is necessary to lift the cylinder back pipe to relax, and the cylinder rose to the top and then fall to the bottom, repeated operation can discharge the air in the hydraulic pipeline, in order to effectively solve the problem.

Q The steering wheel is inflexible when turning the steering wheel
A
The reason for this problem is that the steering steering spring breaks and the steering cylinder leaks. The solution is to turn the direction in place, and you feel that the direction is too light, and it can be clear that the positioning reed has a problem, and you can replace it. If you feel the steering wheel when there is a certain force of the steering wheel, but the steering wheel is very not flexible, and left or right can be 360 degrees of rotation, that is to say, the piston oil seal on the steering cylinder problems, leading to its internal leakage, need to replace the oil seal can be.
