I've been trying to align my 3.5 year old 1022ZPRO for the last 4 days. I've finally realized the reason why I cannot get it aligned. I can align the blade to within .001" parallel to the left miter slot with the blade fully raised. But when I lower the blade 1/2 way, the back of the blade shift to the left .012"
Through trial and error, here's two things I've learned:
The weight of the motor has something to do with the back of the blade being pulled out of alignment when I lower the blade. If I remove the motor, the blade stays in alignment when it is lowered.
The blade is only pulled out of alignment when the saw is at 90 degrees or close to it. If I tilt the blade past say 25 degrees, the blade stays in alignment when I lower or raise the blade.
As it is, the best I can do is to split the difference in the .012" leftward heal shift. I have to adjust the blade at full height so that the back of the blade is shifted .006" to the right. That way when I lower the blade 1/2 way, the back of the blade is .006" to the left.This is still farther out of alignment than the spec'd < .004"
I'm not sure if the blade continues to shift the lower it get because the blade it too low to measure with my alignment tools.
I know there are not many parts to the contractor saw, but I cannot figure out what would be causing this issue. Is there any part that I need to replace? Is is there something that I can adjust to fix this strange shift of the blade when I lower it? Has anyone seen this type of shift before? Do you think .006" is as good as I'll get with a contractor saw? (The reason I ask is because the manual states the blade need to be within .004" parallel to the miter slot.)
Thanks,
