When you say take down manual take down how far. If it is complete disassembly then your better of taking it to a gunsmith. If you try it yourself and your not a smith then buy some antacids and take them first. You will need something to compress the springs with and alignment pins for reassembly. You will also need patience lots of patience. I learned how to work on that model from a schematic in an old gun parts catalog thats all we had. Let me know how it goes.
