What are the important safety precautions I should follow when operating the Craftsman M220?

Key safety precautions include: wearing long-sleeved shirts, long trousers, safety goggles, work gloves, and sturdy footwear; never operating in wet grass or on slopes steeper than 15 degrees; mowing across slopes, never up and down; keeping the area clear of children and pets; stopping the engine before cleaning or repairing; disconnecting the spark plug wire before any maintenance; and never leaving the mower unattended while the engine is running.
