- 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: Usage of spline shaft is recommened if max. torque is more than 280N・m.
- 4: Input pressure must be less than 21MPa (3045.80psi) at maximum.
- 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 implement to protect oil seal.
- 6: ΔP means difference pressure.
