You might need to undo a couple of the heavy wires they use to hold the
big cable bundles in place.

HOWEVER..................

As I finally realized after tuning CS80s for many years, if you're just
doing the usual tuning procedure, you don't have to, and shouldn't raise
the card frame! All the trimmers are accessible with it down. You just
need a flashlight and to push the cable bundles up and out of the way.
Leaving the cards down should make the temperature change less, so the
tuning should hold better when you close up the lid.
