1. Define your needs: Before buying, first define your needs, such as the model of the excavator, its functions and the environment in which it will be used.

2. Check the condition and performance: According to the condition and performance of the excavator to determine whether the vehicle meets your requirements. Pay special attention to the big arm and small arm whether there are cracks or welding marks, which may mean that the machine has been seriously damaged.

3. Price analysis: If there is a big difference between the simple price inquiry before the test drive and your mental expectation, then there is no need to try the machine again. There is a price range you can look at, e.g. 50,000 for 60-200 models as a cut-off point.

4. Check the nameplate information: The nameplate on the excavator usually contains information such as model size, manufacturer, brand logo, frame number, factory number, year of manufacture, etc., which will help you understand the condition of the equipment.
