Turn the wheel from lock to lock (hard left to hard right) a few times to bleed the system.

As MacGyver said, Left to right a few times dont force it if it gets tight.
I installed the same thing last year and did just that as mentioned and perfecto, works great.

thats what I was told also.

Ok, here is a quick lession the way I understand it.
When the cylinder is bottomed out there is an extremely low amount of space between the bottom of the barell & the piston. When the piston is at full stroke one difection it sends all the fluid in that side back to the tank. The other side of the piston/barell is now full of fluid & air. When it travels its full stoke it will purge the fluid/air back to the tank also. There will be some air left, but air rises & that is why the tank is mounted higher than the rest of the system. Every time the system is cycled it purges a little more air untill all the trapped air is gone. Because fluid moves in 2 directions on each side of the pistion there is always a way for air to make its way back to the tank.
Like I said before, when I worked for CAT we never bled a hydraulic system. We'd change a cylinder, hook the hoses back up & cycle the system a few times then top off the tank.
I can't see any difference in what we are doing here with steering systems. It is a 2 way circuit unlike your brake system on your car.

I don't know how what volume of fluid is in the cylinders, but if you have a long length of hose (the hose holds more fluid than that side of the cylinder) the air may not reach back to the orbital (helm) where in enters the pressure/tank circuit. I would rather crack the lines at the cylinder top/bottom while you have someone turning the wheel until you get nothing but fluid. You'll know it, just be careful hydraulic fluid can cut you.

There is no system that self bleeds. Air in the system has to be completly removed from the system in order to get 100% slop free steering.YOU don't want any movement in the drive when traveling past 50 mph ! I have bled many systems with single and twin pumps on triples and it not easy but you better know what you are doing or take it to someone that knows ......
