I have been unable to get the DEC KNOB to come lose on a 8” lx 200 Meade. Any ideas on what to do?

I forgot to say it has set up a couple of years. That is what was told. I just bought it it looks new. It was stored upstairs in a very nice home. The owner said the only reason for selling it was cause he hadn’t used it in two years. Hope that is not a bad thing.

I was able to get it lose by using a flat bottom punch on the ribs of the knob . I tapped it very lightly with a small brass hammer. It came lose on the third tap. Hope this helps everyone who has this problem . Everyone have great viewing . JW

My wife's ETX 90RA had a sticky dec knob. Upon taking the arms apart I found that the two knobs were both just screwed on to the ends of the shaft. I just grabbed both knobs and unscrewed them slightly (took alot of force with pliers). They work smoothly now. The AZ knob also was jumpy. I took it apart and saw that one plastic disc rode inside another. All kinds of oil, grease, graphite was tried to no avail. I finally rubber cemented (in case I needed to undo it) 3 tiny slivers of easy gliders onto the bottom disc spaced equally around. It is smooth as silk now.
