Where can I get a copy of a Breville Express Cooker (EXC15) manual? I had a cooker given to me but alas no "how to use" instructions.

Hi I have the same model - I absolutely love it. The only problem is that the seal is broken and because Breville no longer supply parts I'm using it more as a slow cooker!
It's pretty simple to use:
The basics:
1. Pull the handles apart (note you must have the 'pressure lock - the only sliding knob on the lid) in the 'unlocked position'.
2. Set the temperature on Max (only until the meat, onions etc are brown, then turn down to 1 or 2- just enough to keep the orange button 'popped' on the top of the machine
3. turn the timer (bottom dial on the front of the cooker) to an hour (you can always turn the dial more if needed, but not reduce time) by the time you've browned meat & chopped veges, etc that will be about 10-15 gone. I've never had it pressure 'cooking for more than an hour for anything'
3. re timing - casserole takes about 40 min from when the orange button on top 'pops' up (ie. steam build up enough pressure to cook quickly)
4. don't over fill - there's a little cast iron bump about an inch from the 'top' inside the cooker - that's about the max.
5. if you're cooking meat dishes have the dial on the top 'pressure release dial' on 3 - lighter dishes (e.g. soups) have on 1 or two.
6. until you get use to it keep an eye on the orange button - you get to know what temp to put it on by how much steam is released - it it's hissing away, turn the temperature down.
7. makes great casseroles, rissotto, soups (even with dried beans, only about 40 min)
if you ever find a supplier for seals, post an answer!
