I have a 220/440 v single phase 2.2Kw ac motor driving the

hydraulic pump on a 3 tonnes Tecalemit car lift. It replaces a 1.5Kw 3 phase motor. Problem is that although same speed it is inclined to stall under load and seems to lack the power of the old 3 phase.
The motor is a GEC Kapak Stayrite D100L. The motor case has 9 wires coming out of it to 4 terminations in the connector box plus one to the capacitor. These are: terminal 1:black A3,F8,Unmarked live feed currently on this. Terminal 2: Black 22, Redunmarked. Terminal 3: Black A2 and A41, currently connected to the neutral feed. Terminal 4: one Black and one Red both unmarked.
Can you advise whether or not it is connected correctly to give maximum starting and running torque on 220 volt 50Hz please
