I just started having an issue with my 562xp. Put a chain I haven't used yet this year but it is sharp on. Saw throws some oil but as soon as I put it in the wood, it bogs down and the bar/ chain get very hot. Oil hole on bar is clear and the oiler is working fine. There is a build up of oil flowing out by the oiler with the bar on. The bar is has been pretty beat up and has a lot of wear on it. Is it time to replace my bar?
