Everyone wants to know how to better operate and maintain small excavators. However, there are many incorrect maintenance methods for small excavators, as each person's maintenance content is uneven, which can cause significant damage to the machine over time. Next, let's briefly organize it for your reference!
1. Clean the soil on the surface of the excavator and check if the fasteners are loose.
2.If mini excavators are not used in winter, they should be properly stored and maintained. Only by using it again can it better function;
3. Run the air conditioning system once a month, first warm up the cab, and then let the refrigerant circulate in the air conditioning system for a week, keeping the sealing ring of the air conditioning system with a certain thickness of oil film to prevent refrigerant leakage. Check if the electrical control switch of the excavator is normal;
4. The air filter cannot be disassembled. After dipping cotton yarn in diesel and igniting it, it can be placed in the intake pipe to start the ignition. In this way, the dusty air from the outside is directly sucked into the cylinder without being filtered during startup, causing abnormal wear of components such as pistons and cylinders, and also causing unstable operation of the diesel engine, damaging the machine.
5. The serious consequences of low-temperature load operation: it will cause severe wear and tear of the machine. Therefore, after the ignition of the diesel engine in winter, it should be idling at low and medium speeds for a few minutes, and then put into load operation after the cooling water temperature reaches 63 ℃.
