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 output torqure is more than 280N・m, it is highly recommended to use spline shaft.
4: Input pressure must be less than 21MPa (3045.80psi) at maximum.
5: Max.permissible back pressure is 10.3MPa (1493.89psi), but in the case of operating with more than1.8MPa(261.07psi), drain piping is required to protect oil sealing.
6: ΔP means differentical pressure.
