After purchasing a second-hand excavator, regular maintenance and care are crucial to ensuring the long-term stable operation of the equipment. This article will introduce practical maintenance and care tips to help you extend the lifespan of your second-hand excavator and ensure it performs optimally in various construction projects.

一、日常检查与维护

Daily Inspection and Maintenance

1. 检查液压系统

• 每天检查液压油位，确保液压油充足且干净。定期更换液压油和滤芯，防止系统污染和磨损。

• Check the hydraulic oil level daily to ensure it is sufficient and clean. Regularly replace hydraulic oil and filters to prevent system contamination and wear.

2. 检查发动机

• 每天启动前检查发动机油位和冷却液液位，确保发动机在正常工作温度下运行。定期更换发动机油和空气滤芯。

• Check the engine oil level and coolant level before starting each day to ensure the engine operates at normal working temperature. Regularly replace engine oil and air filters.

3. 检查底盘

• 检查底盘部件，如履带、轮胎和悬挂系统，确保没有明显的磨损或损坏。及时更换磨损严重的部件。

• Inspect undercarriage components such as tracks, tires, and suspension systems to ensure there is no significant wear or damage. Replace severely worn components promptly.

二、定期维护与保养

Regular Maintenance and Care

1. 润滑

• 定期润滑所有运动部件，包括铰接点、臂架和铲斗，以减少摩擦和磨损，延长部件使用寿命。

• Regularly lubricate all moving parts, including pivot points, arms, and buckets, to reduce friction and wear, extending the lifespan of the components.

2. 清洁

• 定期清洁设备，特别是散热器、发动机舱和液压油箱，防止灰尘和杂物积聚，影响设备性能。

• Regularly clean the equipment, especially radiators, engine compartments, and hydraulic tanks, to prevent dust and debris buildup that could affect equipment performance.

3. 检查电气系统

• 定期检查电气系统的连接和电线，确保没有松动或破损。及时更换老化的电线和接头。

• Regularly inspect electrical system connections and wires to ensure there are no loose or damaged parts. Replace aging wires and connectors promptly.

三、季节性维护

Seasonal Maintenance

1. 冬季维护

• 在冬季，确保使用适合低温的液压油和发动机油。每天工作结束后排空液压系统中的积水，防止结冰损坏系统。

• In winter, ensure the use of hydraulic oil and engine oil suitable for low temperatures. Drain water from the hydraulic system daily after work to prevent ice damage.

2. 夏季维护

• 在夏季，定期检查和清洁散热器，确保散热良好。避免长时间高温作业，防止发动机过热。

• In summer, regularly check and clean radiators to ensure proper cooling. Avoid prolonged high-temperature operation to prevent engine overheating.

四、专业保养

Professional Maintenance

1. 定期专业检查

• 每年至少进行一次专业检查，由专业技师对设备进行全面检测和维护，发现潜在问题并及时解决。

• Conduct a professional inspection at least once a year, where professional technicians perform comprehensive checks and maintenance to identify and resolve potential issues.

2. 使用原厂配件
