- 1： Do not drive motor with max. torque or max. pressure in more than 6 seconds.
- 2： Recommended hydraulic oil: ISO-VG32 or same class.
- 3： If output torque exceeds 280N・m, it is highly recommended to use spline shaft.
- 4： Max. Input torque must be less than 21MPa (3045.80 psi).
- 5： Max. permissible back pressure is 7MPa (1015.27psi), but in the case of operating with more than 1.8MPa (261.07 psi), drain piping is required to protect oil sealing.
- 6： ΔP means differential pressure.
