TRA001 height adjustment changes when locked
I have a table mounted TRA001 that I'm having a small issue with. After I set the bit height and lock it, I can see the adjustment knob start to slowly spin when I turn on the router. The bit height doesn't move since I have the router height locked. However, if on my test cut I found that I need to adjust the height slightly, when I unlock the router the router drops because the adjustment has turned. Has anyone else experienced this? I'm not sure what to do about it.
