Oil is important, but if the tools sit form years, that same oil can gum up. You may only need to dissemble, clean, oil, and reassemble.

Look on Ebay and Amazon for rebuild kits. Most cheaper air tool are fairly universal. I still have my old Chicago Pneumatic impact gun I got due to a broken hammer set. A $12 flea market kit and it 's been running for 27 years.
