How far did you have to push it? Did you engage the relief valves to put it in free wheeling position? The two relief valves under the handle "A" when pushed down with the handle allow the fluid to bypass, making it easier to push. When you lift the handle to release the valves for normal operation, one or sometimes both of the valves have a tendency to stick in the down position. Some cautious use of needle nose pliers and some WD40 will often free them up to raise to the operating position. Check to make sure the handle is up and the valve tips are raised in the relief valves.
If the free wheeling handle was not depressed and you pushed it, you may have gotten some air into the system. Check you fluid level and if you add any, make sure to use the relief valve "E" to keep air out of the system.
