How to adjust, not change the bevel on a compound mitre saw

[rokosz]

This is the Hitachi saw in question: How do you adjust a Hitachi compound miter saw? (findanyanswer.com)

Before I chase the Hitachi site, I thought I'd start here.

The link has the obvious, user's manual, answer: When you _want_ to change the bevel for your desired cut.

I need to adjust the _unit_ because my unit when set to 90deg. is not cutting 90. And the bevel adjustment is at its max and won't go that tiny bit more. Its 90+ or - but not 90. No wonder my mitres have been so challenging.

Anybody know how to do it? I understand most of ya'll have probably never used the Hitachi. In general is the concept unusual/rare for saws? Seems like it would be a maintenance item (or a weekly check/adjusment) for a pro.
thanks!

When I followed the links in your post it appeared to address adjustments for squareness to table and fence. Am I missing something?

No, not really. that link is the typical link for practical use. I need the unit maintenance level doc. think I found it, but haven't tried yet: Adjustment Of Components; Bevel Angle Adjustment; Ball Bushing (Linear Bearing) - Hitachi C 12LSH Technical Data And Service Manual [Page 40] | ManualsLib

Yeah, I see what you mean. Maybe someone will pop up that's already been there.
