Is it leaking, or is it just the residual oil dripping from the clutch area after being used? Chain oil remains present within the chain cover rea as well as the chain and bar- this will slowly run off those surfaces and give the impression there is a leak. If. however oil is literally pouring out from underneath the machine when it is not in use and the reservoir is nearly empty each time you come to use is, then you have a leak. Maybe the oil supply line is damaged or come adrift, or more seriously, maybe to have damage to the oil tank itself.
