Excavators are versatile machines that can operate in a wide range of weather conditions, making them all-weather workhorses. Some are used in hot climates, while others operate in extreme cold. The maintenance and care for these machines vary depending on the working environment. In cold weather, the equipment faces more rigorous challenges than usual. How to better operate and maintain the machinery becomes a pressing concern for every user. However, due to the varying levels of maintenance expertise among mini excavator operators, many incorrect maintenance methods exist, which can cause significant damage over time. Below, let's explore the operation and maintenance of mini excavators in cold conditions, hoping to be helpful to all.

Usage and Maintenance of Mini Excavators

1. Clean off the dirt from the excavator's surface and inspect for any loose fasteners.

2. If a compact excavator is left unused during the winter, it should be properly stored and maintained to ensure its performance when put back into use.

3. Run the air conditioning system monthly to warm up the cab, then allow the refrigerant to circulate throughout the system for a complete cycle, maintaining a certain thickness of oil film at the sealant areas of the air conditioning system to prevent refrigerant leakage. Check if the excavator's electrical control switches are functioning properly.

4. Do not remove the air filter. Instead, use a cotton rag dipped in diesel fuel, ignite it, and place it inside the intake manifold as an ignition aid. During the starting process, the dust-laden air from outside will be directly吸入 the cylinder without passing through the filter, causing abnormal wear to parts such as the piston and cylinder. Additionally, this can lead to rough operation of the diesel engine, damaging the machinery.

5. Severe consequences of low-temperature load operations: It can cause severe wear on machinery. Therefore, after the diesel engine starts and catches fire during winter, it should idle at low to medium speed for a few minutes. Once the cooling water temperature reaches 63°C, then proceed with load operations.

Through the above introduction, you should now have a better understanding of "the use and maintenance of mini excavators, as well as maintenance video tutorials." The content provided by the editor of Baodiwo Heavy Industry is a list of precautions to consider when storing excavators during winter. As long as proper protection is in place, your equipment can perform exceptionally well in both cold and hot temperatures. We hope this information is helpful to you.
