Windows maintenance

Well, not on the PC but on the boat windows. After a while the handles get more and more difficult to operate and so after a few years i decided to take them apart. It is just a central screw and then you can take the handle apart. Clean the window and remove old grease, dirt etc. Then take out the o-ring of the handle and clean it as well. Then lubricate it with silicone grease and put everything back together. Tighten the screw slightly and the handle will work like a charm.
