    (X) "FULL" mark

  2. Check the engine oil. Maintain the engine oil level between "ADD" mark (Y) and "FULL" mark (X) on engine oil level gauge (2). Do not fill the crankcase above "FULL" mark (X).


    NOTICE

    Operating your engine when the oil level is above the "FULL" mark could cause your crankshaft to dip into the oil. The air bubbles created from the crankshaft dipping into the oil reduces the oil's lubricating characteristics and could result in the loss of power.


  3. Remove engine oil filler cap (1) and add oil, if necessary. Clean the engine oil filler cap. Reinstall the engine oil filler cap.
