首先要进行外观检查，查看设备是否有明显的损坏、腐蚀和磨损情况。仔细检查机身、底盘、工作装置和液压系统等部位，确保没有严重的结构性问题。
First, conduct a visual inspection to check for visible damage, corrosion, and wear. Carefully examine the body, chassis, working devices, and hydraulic systems to ensure there are no significant structural issues.

操作性能测试
Operational Performance Test

进行操作性能测试，检查挖掘机的发动机启动情况、液压系统工作状态、操作杆的灵敏度和响应速度等。确保设备在各个操作环节都能够正常运行。
Perform an operational performance test to check the engine start-up, the working condition of the hydraulic system, the sensitivity of the control levers, and the response speed. Ensure the equipment operates normally in all aspects.

历史记录查询

查询设备的历史记录，包括使用时间、维护保养记录、是否有重大维修和事故记录等。这些信息能够帮助您全面了解设备的使用状况和寿命。
Check the history records of the equipment, including usage time, maintenance records, significant repairs, and accident history. This information can help you fully understand the equipment's condition and lifespan.

四、价格谈判与合同签订
4. Price Negotiation and Contract Signing

在确定设备质量和性能符合要求后，进入价格谈判环节。了解市场行情，确保价格合理。签订合同时，要明确设备规格、交付时间、付款方式和售后服务等条款，保障双方权益。
Once the equipment's quality and performance meet your requirements, proceed to the price negotiation stage. Understand the market conditions to ensure a reasonable price. When signing the contract, specify the equipment specifications, delivery time, payment terms, and after-sales services to protect the interests of both parties.

五、设备交付与验收
