There is a small hole in the side of the bar that allows the oil to flow into the groove in the bar. If the oilier hole is plugged with sawdust or dirt the oil will run down the side of the bar and out of the saw. There is a gasket that seals the oil reservoir. It is item #B14 on the parts diagrams. This gasket could be damaged allowing the oil to escape the reservoir. The gasket is part #965525002 and is available from I think these would be the most likely causes of your oil leak.

Good luck with your repair!
