First mitre saw. First mistake 6955-20 adjustment gone awry

[podric]

I have a new to me Milwaukee 6955-20.  This thing is a beast at 75lbs.  It isn't small either.

 

The miter bevel was stiff and Milwaukee told me there was no torque spec for it so I backed off the nut a little and loosened it up.

The miter bevel was also not dead center and so read the manual and went to do the adjustment.

I did not use the Milwaukee tool to hold the big red bevel brake arm release.  I used a screw driver.

 

The front 2 torx screws were backed off.  The first time they were backed off I could not move the adjustment screw much without resistance; maybe I should have forced it a bit?

I backed the 2 torx screws further off and the adjustment screw moved with greater range.  Still I was unable to do the minor adjustment on the bevel as the screw did nothing.

I tightened up the 2 torx screws on the front so I could try again later.

 

NOW: the bevel brake release does not stay in the detent search position and I can sense no positive action on the bevel detent.  When the lever does stay up it does not fall on a detent.

 

I am at a loss, I can see inside a little with the scope and can see from the back place but the mechanism is partially hidden from my view via  1" squarish metal plate on a part.

The milwakee rep said maybe tightening the brake cable would help but did not know for sure.

 

How do I get this saw back on track?
