don't oil...they told me they are self oiled whatever that means...I have 4 Husq...Lily 545, SE and EM10 and ER10...Only one that needs oiling is the EM10 which is their cheapest Embro machine I first bought and it's made in Asia...Not Sweden...It was really the first machine they tried having made elsewhere...So that I oil but anything they make in Sweden and most new machine don't need oil...
