I can’t get my saw to oil
For model number 450
Hello Maria, Thank you for the question. You may need to turn up the chainsaw oiler adjustment. Turn it counterclockwise to increase the oil. Hold the machine up and start the throttle. There should be small oil drops as the chain spins. For more information, please provide the serial number and year of manufacture. We hope this helps.
