引言 | Introduction

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、液壓系統檢查 | Hydraulic System Inspection

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. 液壓油檢查 | 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、發動機檢查 | Engine Inspection

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. 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、電氣系統檢查 | Electrical System Inspection

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. 電氣組件檢查 | 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、機械部件檢查 | Mechanical Parts Inspection

1. 檢查磨損 | Check for Wear:檢查鏟斗、臂架和底盤是否有明顯磨損或裂紋。及時更換受損部件，防止問題惡化。

Inspect the bucket, boom, and undercarriage for signs of wear or cracks. Replace damaged parts promptly to prevent issues from worsening.

2. 潤滑檢查 | Lubrication Check:確保所有活動部件充分潤滑，減少摩擦和磨損。

Ensure all moving parts are adequately lubricated to reduce friction and wear.

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.
