Clean the lines. They plug with dirt and sawdust. How do you fix a self oil er?
Open the control screw so that oil just pours out - make sure you have something under to catch the oil. Once it stops coming out, I would blow air into the chamber - don't overdo it. Then I would close the screw and put a little oil in, cover the hole with a rag and stick the air hose under the rag, open the screw a little, blow it, then open it all the way and continue blowing it out. You probably picked up some sawdust particles in the oil. Good luck, cutting season is almost here.
