Here's a link to the manual which will walk you through the disassembly process.
I'd also caution you to be careful. There's a tiny exposed spring that does tend to pop out. I once spent hours on my hands and knees with a flashlight to the ground looking for the shadow of that damn tiny little spring. I don't disassemble mine any more.
I've shot near 10,000 rounds since last doing more than running brass brushes and patches down the barrel and the action with no functional or accuracy problems (in fact I believe the accuracy has increased from when I used to do a full detail strip and clean after each session).
Good luck.
