Okay, gotcha. Someone other than I should respond to this as well.
There should be four pedals (I believe). The outer ones control maching direction: if you have the two splitters in front of you going forward, you can make left and right turns with the pedals. (They're essentially brakes.)
The center two... I don't remember. I know one CAN be for auxiliary hydraulics, but don't remember the function of the other one.
Left joystick: I BELIEVE this one controls swing and boom movement. If you push left, you rotate left; if you push forward, boom goes down. Right joystick: bucket and stick. Forward = stick out; left=bucket curl. I'm not sure on that.
Of course, I didn't think that you would already try that and know that... so...
I don't have my 322B literature with me right now. However, your dealer should be able to provide that free to you, meaning you can figure out what the buttons do without getting an expensive manual. I'm pretty sure you won't find a manual online (I haven't).
Good luck.
