Several common wrong operation methods

　　1.The engine is running, the power take-off is located in the "on", lift handle is located in the "lift" position and lift the clutch. Suddenly make the power take-off, gear pump drive shaft and gear pump is subject to a large impact load, easy to cause early damage (generally occur more for the gear pump drive shaft damage). In the engine running at high speed, the carriage is fully loaded, the winter engine cold when the hydraulic oil viscosity is high, more prominent.

　　2.In the middle of the full lift suddenly lift handle to "down position", this is the carriage is not Xu Xu landing, but rushing down, which will bring a lot of impact to the frame, and even accidents will occur. Therefore, should try to avoid the above operation, such as special circumstances need to be careful operation, as far as possible to slow down the landing speed, do not violently carriage down to the bottom.

　　3.After unloading, do not take off the power take-off or forget to take off the power take-off and then drive, so that the car in the exercise, due to the power take-off operation. The so-called "small cycle" that is the gear pump operation hydraulic oil only in the pump high and low pressure circuit between the cycle. In this case, the temperature of the hydraulic oil rises quickly, easy to cause damage to the gear pump seals, and even occur gear pump "burn pump" phenomenon; in addition, when driving at high speed, the oil pump drive shaft will also be too high under the action of centrifugal force leads to early damage. More serious is the operation of the oil pump means that the hydraulic system has a power source, in the process of driving will be due to various reasons and the carriage lifting accident. Therefore, in order to ensure driving safety when unloading the car, should promptly disconnect the pickup, cut off the power of the gear pump, and then let the vehicle drive.
