Bring the machine up to normal operating temperature. Ensure the engine is off. Remove the oil fill cap, position an oil drain catch pan. Unscrew cap from oil drain tube, let drain. Remove oil filter, lubricate o-ring. Install oil filter and drain plug. Fill to recommended capacity with appropriate oil. Start the engine and run until oil pressure light extinguishes (3- 5 seconds). Turn off the engine. Verify oil level. Check for leaks. Clean any excess oil. With a paint pen or marker, write the current date and engine hours on the new oil filter for quick reference.
