Hey everyone, looking to get some help with a heeling issue on a bosch 4410l miter saw the head is not parallel to the rails. It burns on the right side of the blade and tears on the left. I rectified the issue by shimming between where the arbor housing mounts the head, but Im wondering if that is the correct method for resolving the issue. The fence is straight and square and the rail guides are tight. Thanks in advance for any light that can be shed. Cheers.
