The best way to adjust windage is with the special tool mentioned in other posts here. It looks like a small "C" clamp. About $9 at guns shows. It's the same one used for the SKS.
For elevation, the front post screws up and down, just like the front post on the AR-15. The AK should come with a little tool kit. The kit fits into a metal capsule that fits into the spring loaded trap door in the end of the butt stock. In the tool kit is a flat metal blade about 2" long, that looks like a screw driver blade with no handle. The end opposite the screw driver blade has a small hole that fits down over the front sight post. Use that to turn the post to move it up and down. For leverage on that tool, use the cleaning jag from the tool kit that screws onto the cleaning rod. Put the screw driver blade on the front sight post, and then put the hole of the cleaning jag over the blade at a right angle, and use it to turn the blade.
The manual that you get with a modern AK is virtually worthless. Search the AK forums for the web site where you can download the US Army manual for the AK. I don't have it handy, but will see if I can find the site and post it later.
