Key switches problem

Hi Guys,

Happy Christmas to all.

I own an 18-year-old Monomachine that started to show some trouble after so many years of jams :slight_smile:

6 keys do not work so just wondering if there is any way I could gently remove them to try to clean the contact inside with contact cleaner? Or this is not advisable?

It is really impressive that this thing didn’t break for such a long time.

Thanks, guys.
