I recently found that the laser mark on the Parkside MPKZ mitre saw was no longer lining up with where the blade was cutting on the wood. I am unsure how it became out of alignment as it was once perfect but I needed to find a way to fix it.
After poking around for a few minutes I found that the laser itself is actually moveable and in my case, the screws that hold the laser in place were actually a little bit loose. In the image below, you will see the two screws. The laser can be pushed from left to right to align the laser up with the blade.
You will find that there is a small notch at the upper part of the plate that holds the laser in place. If you loosen the screws slightly, you will be able to slide the laser from left to right. If you line up the notch on this plate with the notch in the piece behind it, you should end up with a laser going down the center of the cutting surface and the blade will now cut down exactly where the laser is pointed.
