The pilot reported that she lifted into a hover in preparation for takeoff and the helicopter began a pilot inducted oscillation due to heavy cyclic control forces. The pilot stated that she overcompensated on the controls and the helicopter rolled over. The pilot reported that during the run-up procedure she disengaged the hydraulic system to check the rotor tip path plane and forgot to reengage the system prior to lifting into a hover. The pilot said there was no mechanical malfunction or failure of any system.
