Check the oil level in sight gauge (2) while the engine is running at low idle. Maintain the oil level within the operating range while the engine is running. Note: The oil level varies significantly when the engine is stopped. The oil level will be considerably higher than the operating range. The oil level should be above the middle of the gauge before the engine is started.
If necessary, remove filler cap (1) and add oil. Clean the filler cap and install the filler cap.
