The one thing K40 owners Love to do is align their optical mirrors. To make the process a little easier here are a couple of guides to assist you.
- HP Perrson has a good guide on his site.
- Here is another guide put together by TimTheFloatingWombat, henceforth called the Floating Wombat Guide. If you use this guide I recommend using a sharpie marker to label your adjustment screws A,B,C as indicated in the guide, makes the adjustment recommendations easier to follow.
