The saw is equipped with an adjustable chain oiler. The oil pump, driven by the drive sprocket, will only pump oil when the engine is running at high enough speeds to engage the clutch and rotate the chain.

To adjust the oil pump, insert a screwdriver in the small notch beneath the clutch and drive sprocket. To increase the flow of oil, turn the screwdriver
The guide bar and saw chain need to be well lubricated during operation to prevent permanent damage from friction and heat. Be sure to check the oil supply to the bar and chain before use.
