引言 | Introduction

在寒冷的冬季，二手挖掘机的维护尤为重要。本文将介绍冬季维护的关键步骤，确保您的设备在低温环境中正常运行。

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、预防结冰 | Preventing Freezing

1. 液压系统 | Hydraulic System:使用防冻液，确保液压油不会在低温下结冰。定期检查和更换液压油，保持系统畅通。

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. 冷却系统 | Cooling System:检查冷却液的防冻能力，确保其在低温下有效工作。必要时更换冷却液。

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

二、保持电池健康 | Maintain Battery Health

1. 电池检查 | Battery Inspection:定期检查电池状态，确保电压正常。清洁电池端子，防止腐蚀。

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

2. 电池保温 | Battery Insulation:在极寒环境下，使用保温套保护电池，防止电量流失和启动困难。

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

三、润滑和防锈 | Lubrication and Rust Prevention

1. 润滑系统 | Lubrication System:使用适合低温的润滑剂，确保所有活动部件在寒冷天气下正常运转。

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

2. 防锈处理 | Rust Prevention:在湿冷环境中，定期进行防锈处理，保护设备不受腐蚀。

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

四、操作前预热 | Pre-Operation Warming

1. 预热发动机 | Warm Up the Engine:启动前，让发动机空转几分钟，使其逐渐升温到工作温度，确保油液循环顺畅。

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

2. 检查系统 | System Checks:预热期间，检查所有系统是否正常运行，确认无异常情况。

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

结论 | Conclusion

通过遵循这些冬季维护步骤，您可以确保二手挖掘机在寒冷天气中保持最佳性能，避免因低温引发的故障。

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