I to have had this problem but the guy in the video showing how to do the lube job just happens to be in my woodworking club. He had me to take a T25 driver and adjust the center bolt on the top and bottom pivot arm where they come out the front of the saw. You have to make the adjustments while the saw is running. It will vibrate if it's to tight or to loose. Just keep adjusting till you find the sweet spot
