引言 | Introduction

正確的維護對于二手挖掘機的長期使用和性能至關重要。然而，很多操作人員在維護過程中容易犯一些常見錯誤。本文將介紹這些維護誤區，幫助您避免。

Proper maintenance is crucial for the long-term use and performance of used excavators. However, many operators often make common mistakes during maintenance. This article will highlight these mistakes and help you avoid them.

一、忽視日常檢查 | Neglecting Daily Inspections

1. 重要性 | Importance:日常檢查可以及時發現小問題，防止其發展成大故障。忽視日常檢查可能導致嚴重的設備損壞和高昂的維修費用。

Daily inspections can detect minor issues early, preventing them from becoming major failures. Neglecting daily checks can lead to serious equipment damage and costly repairs.

2. 建議 | Recommendations:制定并堅持日常檢查清單，確保每次操作前后都進行全面檢查。

Create and adhere to a daily inspection checklist to ensure comprehensive checks before and after each operation.

二、不正確的潤滑 | Incorrect Lubrication

1. 過度潤滑或缺乏潤滑 | Over-Lubrication or Under-Lubrication:過度潤滑會導致潤滑劑積聚和部件損壞，而缺乏潤滑則會增加摩擦和磨損。

Over-lubrication can cause lubricant buildup and component damage, while under-lubrication increases friction and wear.

2. 建議 | Recommendations:遵循制造商的潤滑指南，使用適量的潤滑劑，并定期檢查潤滑系統。

Follow the manufacturer's lubrication guidelines, use the right amount of lubricant, and regularly check the lubrication system.

三、忽視液壓系統維護 | Ignoring Hydraulic System Maintenance

1. 液壓油和濾清器 | Hydraulic Oil and Filters:忽視液壓油和濾清器的定期更換會導致系統性能下降和部件磨損。

Neglecting regular replacement of hydraulic oil and filters can lead to decreased system performance and component wear.

2. 建議 | Recommendations:定期更換液壓油和濾清器，確保液壓系統的高效運行。

Regularly replace hydraulic oil and filters to ensure efficient hydraulic system operation.

四、未能及時更換易損件 | Failing to Replace Wear Parts Timely

1. 影響設備性能 | Impact on Equipment Performance:易損件如鏟斗牙、密封件和膠管需要定期更換，否則會影響設備性能和安全。

Wear parts like bucket teeth, seals, and hoses need regular replacement; otherwise, they can affect equipment performance and safety.

2. 建議 | Recommendations:制定易損件更換計劃，根據使用情況及時更換易損件。

Create a wear parts replacement schedule and replace wear parts timely based on usage.

結論 | Conclusion

避免這些常見的維護誤區，可以延長二手挖掘機的使用壽命，確保設備的最佳性能和安全。

Avoiding these common maintenance mistakes can extend the lifespan of used excavators, ensuring optimal performance and safety.
