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 φ1″ shaft is used, it is highly recommended to use motor under condition that output torque is less than 280N・m. If actuating with more than 280N・m, it is highly recommended to use spline shaft or φ32 shaft.
4: Max. input pressure must be less than 30.9MPa (4481.67psi).
5: Max.permissible back pressure is 7MPa (1015.27psi), but in the case of operating with more than1.8MPa(261.07psi), drain piping is required to protect oil sealing.
6: ΔP means differential pressure.
