引言 | Introduction

在購買二手挖掘機時，發現潛在隱患至關重要。本文將介紹一些實用的方法，幫助您識別和避免潛在的問題。

Identifying potential hidden issues is crucial when buying a used excavator. This article provides practical methods to help you recognize and avoid potential problems.

一、仔細檢查液壓系統 | Thoroughly Inspect Hydraulic Systems

1. 檢查泄漏 | Check for Leaks:檢查液壓軟管和接頭是否有泄漏跡象。泄漏可能表明系統存在問題，修復成本高。

Inspect hydraulic hoses and fittings for signs of leaks. Leaks may indicate system issues that can be costly to repair.

2. 監測液壓油 | Monitor Hydraulic Oil:液壓油的顏色和氣味可以反映系統的狀況。油液變黑或有異味可能預示著內部磨損或污染。

The color and smell of hydraulic oil can reflect the system's condition. Darkened oil or unusual odors may indicate internal wear or contamination.

二、檢查發動機狀況 | Check the Engine Condition

1. 啟動和運轉 | Start and Run the Engine:觀察啟動是否順利，發動機運轉是否平穩。如果有異常聲音或排煙顏色異常，可能存在發動機問題。

Observe if the engine starts smoothly and runs steadily. Unusual noises or abnormal exhaust color may indicate engine problems.

2. 檢查液位和泄漏 | Check Fluid Levels and Leaks:確保所有液位正常，檢查是否有漏油或其他液體泄漏的跡象。

Ensure all fluid levels are normal and check for signs of oil or other fluid leaks.

三、檢查電氣系統 | Inspect the Electrical System

1. 測試電池 | Test the Battery:檢查電池是否完好，連接是否緊密。電池電量不足可能影響設備性能。

Check if the battery is intact and connections are secure. Low battery power can affect equipment performance.

2. 檢查電氣組件 | Inspect Electrical Components:確保所有電氣組件正常工作，包括燈光、儀表和控制系統。

Ensure all electrical components are functioning correctly, including lights, gauges, and control systems.

四、進行實地操作測試 | Perform an On-Site Operation Test

1. 試駕設備 | Test Drive the Equipment:進行實際操作，觀察設備的反應和操控性。任何不正常的振動或噪音都可能是潛在問題的信號。

Conduct actual operation and observe the equipment's response and handling. Any unusual vibrations or noises could signal potential issues.

2. 測試所有功能 | Test All Functions:確保所有功能和附件正常工作，包括挖掘臂、鏟斗和旋轉系統。

Ensure all functions and attachments are working properly, including the boom, bucket, and rotation system.

結論 | Conclusion

通過這些檢查方法，您可以有效識別二手挖掘機的潛在隱患，確保購買到高質量的設備。

By following these inspection methods, you can effectively identify potential hidden issues in used excavators, ensuring you purchase high-quality equipment.
