Note:
- A simultaneous maximum torque and maximum speed are not recommended.
- ∆Bar refers to true pressure difference between inlet port and outlet port.
- Continuous Rating means that the motor may be run continuously at these ratings.
- Intermittent operation refers to that the motor running time must not exceed 10% per minute under this condition.
*To assure the best orbital motor life, run it for approximately one hour at 30% of rated pressure before application to full load. Be sure this motor is filled with fluid before any load applications.

Tips: Troubleshooting of hydraulic orbital motor
| Failures | Reasons | Solutions |
| Hydraulic orbital motor temperature is too high | Overloaded | Load as required |
| The parts are damaged, especially the stator | Replace damaged parts | |
| Excessive noise | The hydraulic system has air | Exclude the air in the system according to the operation precautions |
| Overspeed | Adjust motor speed | |
| Parts are damaged | Replace damaged parts | |
| Oil leakage at the shaft end | Damaged or scratched sealing ring | Replace the sealing ring |
| Dirt or water in the input end causes the shaft to rust | Remove spline rust | |
| Excessive radial load | The radial load shall not exceed the specified value | |
| Excessive back pressure | Connect to external drain pipe | |
| Oil leakage on both sides of the stator | O ring is damaged | Replace the sealing ring |
| Dirt or burrs on the joint surface | Disassemble, clean and deburr | |
| Back cover bolts are not tight | Tighten the bolts | |
| Shaft does not rotate | Work device stuck | Check working device |
| System problem | Check the system | |
| Large radial axial load | Check installation | |
| Insufficient torque | The oil temperature is too high or the oil viscosity is too low | Enhanced cooling |
| The motor efficiency is reduced due to the wear of the rotor or the small linkage shaft | Replace worn parts |
