Our Xiangjin brand aerial work vehicles need to be maintained and preheated in winter, especially when the temperature drops below zero.

The first step to preheat the aerial work vehicle is to turn on the engine; the second step is to hang up the power take-off device; the third step is to prop up the horizontal legs and open them, get on the vehicle after passing through, open the unloading valve, and preheat for another 10 minutes. The fourth step is to raise the arm 20 degrees, try not to extend the arm, make a steering movement, let the oil circulate, and preheat for five minutes. After turning, do two actions, lift and lower the arm, and do not make the amplitude too large, so that the oil circulates slowly for five minutes. The last important action is to flip the frame back and forth, repeating more than a dozen times.

Only when the aerial work vehicle is properly maintained can it be used for a longer time.
