How do you drain oil on a husqvarna model 61?

To drain the oil on a Husqvarna Model 61 chainsaw, first ensure the unit is off and cool. Locate the oil drain plug, typically found at the bottom of the oil reservoir. Use a suitable container to catch the old oil, then remove the plug to allow the oil to fully drain out. Once drained, replace the plug, and refill with fresh oil according to the manufacturer's specifications.
