a quick way to test if the oiler is putting out enough oil on the chain is to put a piece of clean cardboard or white paper down, start & run the saw a few inches above the paper/cardboard. You should see a light line of oil on the cardboard/paper. If ther is no evidence of it putting out oil take the saw to your Husqvarna dealer & have them check it out. You must first check to see that the oiler port on the saw & bar are clear of debris & the edge of the saw that the chain rides in is also clear of debris so the oil can ge to the chain.
