Turn the drain plug valve 1/4 turn counterclockwise while gently pulling the valve away from the engine to open the oil drain valve. 4. Allow oil to drain into a suitable container. 5. Reverse STEPS 4-3 to close the oil drain valve and reinstall the drain cap. IMPORTANT: Used motor oil may cause skin cancer if repeatedly left in contact with the skin for prolonged periods. Although this is unlikely unless you handle used oil on a daily basis, it is still advisable to thoroughly wash your hands with soap and water as soon as possible after handling used oil. NOTE: Please dispose of used motor oil in a manner that is compatible with the environment. Check with your local municipality for proper disposal procedure. Do not throw it in the trash or pour it on the ground. 1 2 (a) (a) (b) 3 (a) Figure 6-1 8
