On my MTS 1200 (also a Termi with the same baffle arrangement) I use a large spring hook fitted round the cross piece in the baffle. I have a large adjustable wrench that I fit over the shank of the spring hook and then use it to tap the handle of the hook so that it behaves like a slide hammer and pulls the baffle out.
I've never had this trouble with my Scrambler because the baffle has never been fitted
