[sdiy] Casio FZ-1 keyboard maintenance

[Marcel Massana]

Hello,

I'm newbie to this list, so my apologies if it is not the best place to ask.

I have an old Casio FZ-1 sampler that I used to play more than 10 years ago
in my home midi studio. I used it mainly as a master kbd (actually a good
one: presure, velocity and after touch), but also made and played some
samples with it. I stoped making music for several reasons (studying, work,
marriage, sons, ...) but I recently retrieved it to actualize my studio.
Well, the fact is that some keys doesn't respond correctly, I supose it is a
problem of dust within its nechanism because the keyboard hasn't been used
in this lapse of time.

So, can anybody tell me what should I do to repair/clean by myself this
keyboard, or point me where can I find this information?

TIA,
