引言 | Introduction

在寒冷的冬季，二手挖掘機的維護尤為重要。本文將介紹冬季維護的關鍵步驟，確保您的設備在低溫環境中正常運行。

Proper maintenance of used excavators during the cold winter months is crucial. This article provides key winter maintenance steps to ensure your equipment operates smoothly in low temperatures.

一、預防結冰 | Preventing Freezing

1. 液壓系統 | Hydraulic System:使用防凍液，確保液壓油不會在低溫下結冰。定期檢查和更換液壓油，保持系統暢通。

Use antifreeze to ensure hydraulic oil does not freeze in low temperatures. Regularly check and replace hydraulic oil to keep the system running smoothly.

2. 冷卻系統 | Cooling System:檢查冷卻液的防凍能力，確保其在低溫下有效工作。必要時更換冷卻液。

Check the antifreeze capability of the coolant to ensure it works effectively in low temperatures. Replace the coolant if necessary.

二、保持電池健康 | Maintain Battery Health

1. 電池檢查 | Battery Inspection:定期檢查電池狀態，確保電壓正常。清潔電池端子，防止腐蝕。

Regularly inspect the battery to ensure normal voltage. Clean the battery terminals to prevent corrosion.

2. 電池保溫 | Battery Insulation:在極寒環境下，使用保溫套保護電池，防止電量流失和啟動困難。

In extremely cold environments, use insulation covers to protect the battery, preventing power loss and starting difficulties.

三、潤滑和防銹 | Lubrication and Rust Prevention

1. 潤滑系統 | Lubrication System:使用適合低溫的潤滑劑，確保所有活動部件在寒冷天氣下正常運轉。

Use low-temperature lubricants to ensure all moving parts operate smoothly in cold weather.

2. 防銹處理 | Rust Prevention:在濕冷環境中，定期進行防銹處理，保護設備不受腐蝕。

Regularly apply rust prevention treatments in cold and damp environments to protect the equipment from corrosion.

四、操作前預熱 | Pre-Operation Warming

1. 預熱發動機 | Warm Up the Engine:啟動前，讓發動機空轉幾分鐘，使其逐漸升溫到工作溫度，確保油液循環順暢。

Allow the engine to idle for a few minutes before starting work to gradually warm up to operating temperature, ensuring smooth fluid circulation.

2. 檢查系統 | System Checks:預熱期間，檢查所有系統是否正常運行，確認無異常情況。

During warming up, check all systems to ensure they are operating normally and there are no abnormalities.

結論 | Conclusion

通過遵循這些冬季維護步驟，您可以確保二手挖掘機在寒冷天氣中保持最佳性能，避免因低溫引發的故障。

By following these winter maintenance steps, you can ensure your used excavator maintains optimal performance in cold weather, preventing failures caused by low temperatures.
