Check out PDF page number 392 (Section 8.4) of the Series III service manual here…
http://www.fairlightus.com/Downloads/index.php?dir=Historical%2F
Complete with a picture showing how to do it!
There is also a Series II Service manual scanned, unfortunately the person who scanned this manual omitted the very page you need.
As far as I remember the IIX keyboard and III keyboard are pretty much identical except for the left hand control panel, the I/II/IIX had 3 sliders, the III have a pitch bend wheel, anyhow so the manual for the III should be good enough.

Subject: [Fairlight-CMI] cleaning inside music keyboard
Hi,
Anyone out there with experience in opening up the music keyboard of a
IIx ?
I tried to lift the top cover yesterday but just didn't dare to put
more force behind it.
I followed the route from the service manual but the top would only
move for about 50 mm or so.
I remember reading that it was hard to do but it must me possible...
Any tips or tricks here?
cheers,
David
