In today's increasingly competitive second-hand excavator market, repair and maintenance have become the focus of users. Our company is well aware of this and has established a strict management system for the repair and maintenance of second-hand excavators, committed to providing customers with reliable and efficient equipment. We bring you some practical tips for excavator repair and maintenance. In terms of daily inspection, before work every day, you must carefully check the appearance of the excavator, including whether the body, crawler, bucket, etc. are damaged. For example, pay close attention to whether the crawler is loose or broken, otherwise it may cause the crawler to fall off and delay the work.
At the same time, the oil and coolant levels must be ensured to be normal. Insufficient oil will seriously wear the engine, and insufficient coolant will easily cause the engine to overheat. The hydraulic oil level and oil temperature should not be ignored either, as they are crucial to the critical hydraulic system of the excavator. Regular maintenance is even more critical. Strictly replace the engine oil, oil filter, air filter and fuel filter in accordance with the manufacturer's regulations. Generally, the engine oil and oil filter are replaced every 250 hours, and the air filter is replaced every 500 hours. The hydraulic oil and filter element also need to be checked and replaced regularly, and it is recommended to be done every 2000 hours to maintain the excellent performance of the hydraulic system. For the pins, cylinders and other parts of the excavator, add grease on time to reduce wear. For example, the pins of the boom and dipper rod should be filled every 100 hours. Engine maintenance is also not sloppy. Keep the engine clean and regularly clean the dust and debris on the radiator to prevent overheating. Use high-quality fuel to avoid impurities from damaging the engine. The electrical system maintenance also needs to be taken seriously. Check the battery power and electrode cleanliness regularly to ensure sufficient power. At the same time, pay attention to whether the wires and plugs are loose or damaged to prevent short circuits and leakage. Especially in winter, replace the engine oil, coolant and hydraulic oil suitable for low temperatures in advance, and drain the water in the water tank after stopping to prevent the water tank from freezing and cracking.
Our company relies on such a strict maintenance system to ensure that every second-hand excavator can be delivered to customers in the best condition. Our persistent pursuit of quality is only to win your trust and provide a solid guarantee for your engineering career.
