On this saw I don't think there is any adjustment on the chain and bar oiler. It is normal for these saws to leak a fair amount of oil back off of chain bar and sporocket after use. As long as it is cutting good for you I would not worry about it. It may help you some if you make sure that the chain,drive sprocket, and chain guide are kept clean so there is less build up of sawdust to gather oil. I am happier with a little too much oil as opposed to not enough as it will extend the life of your bar and chain. Thank you.
