Air compressor air filter and oil change
Compressors do need to have the oil changed usually based on hours of operation. Since it has been 10 years I would change the oil. The filter is hard to see in the photo. I usually blow air on my filters to clean them if working in dusty areas, Sawdust blows out easily dirt tends to build up. Shine a light in the filter can you see the light on the other side? If no time to replace. Maybe you will get another 10 years but I would change the oil a bit more often.
