How do I stop bar oil from leaking out of my Stihl 026?

you will always get a degree of oil which appears to be leaking from the underside of any chainsaw, but in reality this is just excess oil from the oil pump pipes which drains off when the pump has stopped when the machine is switched off- that is perfectly normal. If you are getting a continuous flow- even when the machine is not operating then you must have a hole in the oil feed pipe as the oil cannot continue to flow if the pump is not operational.
