1. Whether it is large digging or small digging, try to walk as short as possible. If the long-distance walking distance is too long, it will damage the digging machine's walking wheel. When walking, try to make the road flat, especially when walking in constant time and adding uphill. You must use a slow gear, if necessary, use a hook to match, do not let the walk have too much compound which is very hurt walking.
 
2. The planetary gear box must be filled with gear oil. After the initial use, the gear oil should be replaced once every three months. After that, the gear oil should be replaced every one year according to different working conditions. After the running motor runs for a period of time, the rear cover of the gear box should be disassembled, and the wear of the gear box should be checked regularly for timely maintenance.
        3. During the operation of the traveling motor, the working condition of the system oil circuit and the motor gear oil should be checked frequently. If the system pressure is abnormally increased, the traveling motor leaks, abnormal temperature rise, vibration noise or abnormal pressure pulsation, stop immediately. Identify the cause and promptly overhaul.
 
       4. When the excavator's travel motor is weak or the system has abnormal conditions, it should stop immediately and check whether the leakage of the hydraulic motor is normal. If there is a large amount of leakage, the hydraulic motor is damaged and needs to be repaired or replaced.
 
       5. It is recommended to stop the excavator travel motor for 1-2 hours after continuous operation for 15 minutes.
 
6. The safety motor is set to drive the circuit of the traveling motor. For example, the hydraulic motor is a radial piston motor, the relief pressure setting value does not exceed 22 MPa, the hydraulic motor is a cycloidal hydraulic motor, and the overflow pressure does not exceed 17 MPa. The setting pressure of the motor relief valve can be up to about 35Mpa according to
