1. Check the machine winding, motor cover temperature, motor vibration and internal noise. 

2. Check the wheel condition, whether it is complete or not.

3. For the rear bearings, check the bearing temperature and motor vibration.

4. Check the temperature of hydraulic couplers to avoid excessive temperature.

5. For the front bearing, check the bearing temperature and motor vibration.

6. Check the vibration value of reducer, the reducer temperature and internal noise.
