Siphon/pump method: Use a siphon, such as the Arnold Siphon Pump, to remove the oil directly from the oil fill tube and deposit it into an approved container.
Tilt method: Tilt the mower on its side, and use the dipstick tube as a drain. It’s best to wait until the mower runs out of fuel or the fuel is removed. A siphon can be used to transfer the fuel from the tank into an appropriate container.

Insert the pump/siphon tube into the dipstick tube until it reaches the bottom of the oil container.
Tilt method: Place an appropriate catch container under the dipstick tube. Also make sure that this is opposite the air cleaner so that oil doesn’t contaminate the air filter.
STEP 6: DRAIN THE OIL
Siphon method: Manually siphon out the oil. Be careful as the oil may be hot and could cause burns if it is too warm. Tilt the unit towards the side the dipstick tube is located to remove as much oil as possible.
Tilt method: Carefully tip the mower in the direction of each catch container. Keep tilting the mower, making sure the oil is going into the catch container. Hold in this position until the oil flow slows to just a drip. Make sure the mower is tilted air cleaner side up to prevent oil contaminating the air filter.
