Small excavators should be kept and maintained if they are not used in winter.

Small excavators should be kept and maintained if they are not used during the winter. The best performance can only be achieved when used again. The specific maintenance measures are as follows:

      1. Clean the dirt on the surface of the small excavator and check for loose fasteners.

      2. Check whether the antifreeze liquid level and oil level are normal, check whether the oil quality is normal, and check the antifreeze level of the fuel.

      3. If the weather is particularly cold, the small excavator has a long downtime, please drain the engine coolant. At the same time, in order to prevent the battery from feeding, the battery must be removed and placed in a warm place for storage.

      4. Start the engine running once every time. If the antifreeze liquid level and the oil level are lower than the normal oil level, please add it to normal before starting. In cold weather, put the key in the preheating position until the preheating light is on (multiple times to repeat the preheating), then start the engine, and after 5-10 minutes of idle running, operate the cylinders 5-10 times without load. The journey is small 5-10MM. Finally, the engine rotation speed is the highest, and each cylinder is operated 5-10 times, and the left and right rotations and the forward and backward movements are operated 3 times each time. Until the system temperature rises to 50-80 degrees, it can run normally. Continue to make all the working devices operate for 5-10 minutes and then stop the engine.

      5. Diesel should be replaced with -10 to -30 models. It depends on the area where it is located. The more northerly the area is, the more diesel is added. In addition, the diesel filter should be replaced. The oil should be replaced with the local thick. The engine oil and the oil filter are also replaced. The hydraulic system has to be replaced in time, and the conditional fuel tank should be kept warm.

      6. The heat dissipation system should carefully check whether the hose is aging and broken. If there is any problem, it should be replaced in time because these places are more prone to problems in winter. If there is a condition to provide hot water, the water tank should be heated every day to better start the engine, but be careful not to forget to release the water. The reason why antifreeze is not promoted is that it is not easy to start the engine by adding antifreeze in a particularly cold area.
