- 1： Do not drive motor with max. torque/max. pressure in more than 6 seconds.
- 2： Recommended hydraulic oil: ISO-VG32 or same class.
- 3： If φ25.4 shaft is used, it is highly recommended to use motor under condition that output torque is less than 280N・m.
- 4： Max. input pressure must be less than 30.9MPa (4481.67psi) and do not exceed max. output torque.
- 5： Max.permissible back pressure is 7MPa (1015.27psi), but in the case of operating with more than 1.8MPa(261.07psi), drain piping is required to protect oil sealing.
- 6： ΔP means differential pressure.
