It´s got the Schaller JT590, presumably, so that´s a really nice Floyd. Basically the best stock/OEM trem of the era, and everyone used it even on high end builds when the OFR wasn´t available for manufacturers. One common thing to watch out for is wobbly pivot posts - just wrap them in some plumbers tape until they´re snug in the inserts. Other than that you can just clean it, dab a drop of machine oil on the knife edges and make sure everything is screwed down the right amount of tight.
The main fault with these is that the baseplate is too soft to maintain the threads for the intonation screws. These often strip, leading to tuning issues and eventually losing grip of the saddles. You could buy a new baseplate from Schaller (revised with hardened inserts for the threads at some point later on in the 90s) for like 35$ back in the day, but they´re more like 125$ these days and at that point you might just as well change the whole thing even if it´s more expensive. I refurbished dozens of them earlier, but these days I hesitate slightly when I see a guitar with one and do the math if it´s worth the extra expense. More often than not you can see that at least one saddle is way off the intonation pattern - pulled up hard to the screw - which is a sign that the baseplate is shot.
