Since there appears to be only one work port I suspect running the motor would supply oil to the lift & with motor off the handle would lower the load. If this is correct then you could plumb that port to a 4 way 3 position valve to control a double acting cylinder. You will need a way to connect the tank line to the reservoir below oil level though for this to work. You would not use the manual valve on the power unit.
