tighten the screw that lets the jack down, grab the saddle, and pull it up slowly all the way. let it back down.. make sure the fluid is full, top off as needed.
do this a few times and the system should be bled and work.. if it doesn't work, then it's time to dig in and start replacing seals..
I should try that as well on my big jack, it likes to bleed down. It may be time to take it to the local hydraulics shop if that doesn't fix it.
Has anyone ever replaced the O-rings on a jack before?

Is it difficult? My Jack is leaking oil faster than I can buy it.
I have a torin big red jack from hf I think, and tried the "pull the saddle up from the bottom" trick that was recommended by novaderrik, and it worked! It was only moving on the last 15-20% of the stroke and I was getting ready to look for a replacement, now it lives on a bit longer.

I'll have to give that a shot too. I've got 2 dead jacks that I haven't had any luck fixing/adjusting regardless of net surfing advice.
There is a guy over on the Garage Journal forum who sells rebuild parts for most any hydraulic jack. He posted a pretty good thread specifically on how to rebuild imported jacks: http://www.garagejournal.com/forum/showthread.php?t=51105 There were also several threads on rebuilding US jacks like Walkers and Blackhawks.
